Overview In 2019, a novel coronavirus emerged called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19). Initially identified in Wuhan, China, COVID-19 spread internationally and became a global pandemic. Most pediatric COVID-19 cases were milder than in adults, but in the early Spring of 2020, a new inflammatory syndrome emerged in children who had evidence of prior SARS CoV-2 infection, called Multisystem Inflammatory Syndrome in Children (MIS-C). As of March 2021, there were approximately 2,592,619 cases of COVID-19 in people under 18 in the United States and 300 deaths. Of all American cases, 2.1% were in children aged 0 to 4 years old, and another 10.2% were in those aged 5 to 17. Prevalence varies by age, with estimates ranging from 17% for children under 2 years old to 25% of children ages 6 to 10 years old, and 23% in 10 to 14 years old. The severity of the disease is generally lower for children, with only 1% to 5% of pediatric cases qualifying as severe versus to 10% to 20% in adults. This finding is thought to reflect the lower levels of angiotensin-converting enzyme 2 expression in alveolar cells, which is the mechanism by which SARS-CoV-2 enters cells. Being older than 12 years and having a high initial C-reactive protein (CRP) are risk factors for admission to a pediatric intensive care unit, and high CRP, leukocytosis, and thrombocytopenia are risk factors for organ dysfunction. Viral load and young age, specifically children under 1 year of age, are other risk factors for more severe disease. This study describes the features, diagnosis, and treatment of pediatric COVID-19 and MIS-C based on the data available at the time of publication.

Neurological manifestations of SARS-CoV-2 infection in hospitalised children and adolescents in the UK: a prospective national cohort study
Overview The spectrum of neurological and psychiatric complications associated with paediatric SARS-CoV-2 infection is poorly understood. This study aimed to analyse the range and prevalence of these complications in hospitalised children and adolescents. A national cohort study was conducted in the UK using an online network of secure rapid-response notification portals established by the CoroNerve study group. Patients were excluded if they did not have a neurological consultation or neurological investigations or both or did not meet the definition for confirmed SARS-CoV-2 infection (a positive PCR or respiratory or spinal fluid samples, serology for anti-SARS-CoV-2 IgG, or both). Individuals were classified as having either a primary neurological disorder associated with COVID-19 (COVID-19 neurology group) or PIMS-TS with neurological features (PIMS-TS neurology group). The denominator of all hospitalised children and adolescents with COVID-19 was collated from National Health Service England data. This study identified key differences between those with a primary neurological disorder versus those with PIMS-TS. Compared with patients with a primary neurological disorder, more patients with PIMS-TS needed intensive care, but outcomes were similar overall.

Overview
HIV disease is caused by infection with HIV-1 or HIV-2, which are retroviruses in the Retroviridae family, Lentivirus genus. Human immunodeficiency virus (HIV) is a blood-borne virus typically transmitted via sexual intercourse, shared intravenous drug paraphernalia, and mother-to-child transmission (MTCT), which can occur during the birth process or during breastfeeding. The patient with HIV may present with signs and symptoms of any of the stages of HIV infection. No physical findings are specific to HIV infection; the physical findings are those of the presenting infection or illness. Examples of manifestations include acute seroconversion manifests as a flulike illness, consisting of fever, malaise, generalized rash, generalized lymphadenopathy is common and may be a presenting symptom. This course covers the screening, diagnosis, medication and management of Aids.

COVID-19 among dentists in the United States A 6-month longitudinal report of accumulative prevalence and incidence
Overview In 2020, the Centers for Disease Control and Prevention and the American Dental Association released COVID-19 infection control interim guidance for US dentists, advising the use of optimal personal protection equipment during aerosol-generating procedures. The aim of this longitudinal study was to determine the cumulative prevalence and incidence rates of COVID-19 among dentists and to assess their level of engagement in specific infection control practices. US dentists were invited to participate in a monthly web-based survey from June through November 2020. The proportion of dentists tested for COVID-19 increased over time, as did the rate of dentists performing aerosol-generating procedures. Enhanced infection prevention and control strategies in the dental practice were reported by nearly every participant monthly, and rates of personal protection equipment optimization, such as changing masks after each patient, dropped over time. US dentists continue to show a high level of adherence to enhanced infection control procedures in response to the ongoing pandemic, resulting in low rates of cumulative prevalence of COVID-19. Dentists are showing adherence to a strict protocol for enhanced infection control, which should help protect their patients, their dental team members, and themselves. COVID-19 infections among practicing dentists will likely remain low if dentists continue to adhere to guidance.

General Anxiety in Dental Staff and Hemodynamic Changes over Endodontists’ Workday during the Coronavirus Disease 2019 Pandemic: A Prospective Longitudinal Study
Overview The aim of this study was to assess general anxiety levels in endodontists and dental assistants related to different conditions during the pandemic and lockdown and to evaluate hemodynamic changes in endodontists’ heart rate (HR), blood pressure, and blood oxygenation during their workday. Anxiety levels in endodontists and dental assistants were recorded weekly during the state of alarm declared because of the coronavirus disease 2019 pandemic. Hemodynamic parameters were monitored using a sphygmomanometer for HR and blood pressure and a pulse oximeter for oxygen saturation.
Measurements were taken before and after each root canal treatment as well as on arrival at the clinic and at the end of the working day. Rest data, recorded every Saturday, served as a control. Endodontists perceived higher anxiety levels of anxiety during anaesthesia inoculation and dental assistants during the dental unit’s disinfection and equipment material. There was a significant increase in the cardiovascular response in all endodontists in the clinic registrations compared with rest data. Values were higher in the strict confinement period and significant for HR when arriving at the clinic.
Levels of general anxiety were higher during the first weeks. The chief perceived factors related to anxiety in endodontists and dental assistants were the risk of contagion and protection measures. Higher HR and blood pressure levels were registered during the workday, especially when arriving at the clinic.

Occupational health practices among dental care professionals before and during the COVID-19 pandemic
Overview The COVID-19 pandemic has posed a substantial burden on dental care professionals. While dentistry is known as one of the most exposed and high-risk professions, dental care professionals are indeed at even greater risk. The aim of this study was to assess knowledge, attitudes, occupational health practices, personal protective equipment usage, and mental stressors during COVID-19 pandemic among dental care professionals. Ongoing training on infection control, occupational health practices, and PPE usage can prevent the transmission of COVID-19 among dental care professionals and the public. Lack of adequate personal protective equipment (PPE) is a burden for applying occupational health practices in dental clinics and present a risk to the public. COVID-19 may contribute to developing psychological stress and disrupt healthy work-life balance among dental professionals.

Overview Oral healthcare professionals are at increased risk of infection by SARS-CoV-2. The aim of this study was to evaluate the prevalence of COVID-19 in a population of workers who provided services during the COVID19 pandemic at a dental care and educational institution in the Buenos Aires Metropolitan Area. This was a descriptive, cross-sectional study including 358 workers who provided essential services during the first 180 days of the COVID-19 pandemic at the Dental Hospital at Buenos Aires University School of Dentistry (FOUBA). Following epidemiological data, these workers underwent diagnostic testing for COVID-19 (1- nasal or throat swab tests; 2- blood test for enzyme-linked immunosorbent assays [ELISA]; 3- commercial rapid serology test). Three diagnostic tests were implemented. Rapid tests were performed on 290 subjects, with 255 negative results For this sample of dentists, dental assistants and nonclinical personnel, the weighted prevalence of COVID-19 was 4%.

Is there an association between oral health and severity of COVID-19 complications?
Overview The new coronavirus SARS-CoV-2 was first detected in late 2019 and has quickly developed into a global pandemic. Age is one of the highest risk factors for developing severe symptoms of COVID-19, the disease caused by infection with SARS-CoV-2. Thus, individuals over the age of 65 and those living in long-term care facilities are especially vulnerable to morbidity and mortality due to infection with SARS-CoV-2. However, persons with chronic lung disease, moderate to severe asthma, severe obesity, diabetes, chronic kidney disease, and liver disease are also at high risk for severe COVID-symptoms.
Most patients with severe complications from COVID-19 have underlying conditions such as obesity, diabetes, and hypertension. In parallel, there is growing evidence for a link between periodontitis and non-oral systemic diseases. The oral cavity is also a reservoir for respiratory pathogens, and patients with periodontal disease are more likely to develop hospital-acquired pneumonia than healthy individuals. This study therefore hypothesizes that improving oral health could decrease the severity of COVID-19 symptoms and reduce the associated morbidity.

Overview The coronavirus family is a group of zoonotic viruses with some recognized reservoirs particularly some bats. A novel coronavirus emerged in the province of Wuhan (China) in December of 2019.The number of infected patients with serious respiratory infection quickly spread around the world to become a global pandemic. The clinical presentation and viral pathogenesis of the coronavirus disease named COVID-19 indicated that the virus is transmitted from person to person through infected droplets entering the respiratory mucosa. Close contact with infected individuals particularly in crowded environments has characterized the rapid spread of the infection. Clinical manifestations of the viral infection have mentioned the presence of some ocular findings such as conjunctival congestion, conjunctivitis and even corneal injury associated with the classical COVID-19 infection. Some animal models of different coronaviruses eye infection shave described the viral pathogenesis through tear and conjunctival sampling. On the other hand, we are recommended protective measure to prevent contagion and limit the spread of the virus in health care professionals and contact lenses wearers.

Coronavirus Disease 19 (COVID-19): Implications for Clinical Dental Care
Overview: The recent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its associated coronavirus disease has gripped the entire international community and caused widespread public health concerns. Despite global efforts to contain the disease spread, the outbreak is still on a rise because of the community spread pattern of this infection. This is a zoonotic infection, similar to other coronavirus infections, that is believed to have originated in bats and pangolins and later transmitted to humans. Once in the human body, this coronavirus (SARS-CoV-2) is abundantly present in nasopharyngeal and salivary secretions of affected patients, and its spread is predominantly thought to be respiratory droplet/contact in nature. Dental professionals, including endodontists, may encounter patients with suspected or confirmed SARS-CoV-2 infection and will have to act diligently not only to provide care but at the same time prevent nosocomial spread of infection. Thus, the aim of this article is to provide a brief overview of the epidemiology, symptoms, and routes of transmission of this novel infection. In addition, specific recommendations for dental practice are suggested for patient screening, infection control strategies, and patient management protocol. Acknowledgement

Severe Distress – COVID 19
Overview
Since the emergence of the 2019 novel coronavirus (SARS-CoV-2) infection in December 2019, the coronavirus disease 2019 (COVID-19) has rapidly spread across the globe. The clinical spectrum of patients with COVID-19 ranges from asymptomatic or mild symptoms to critical disease with a high risk of mortality.
Coronavirus disease 2019 (COVID-19) is the illness associated with the novel coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus was initially noted during an outbreak of respiratory illness in the population of Wuhan, the capital of Hubei province, China. The first cases were seen in November 2019, with COVID-19 quickly spreading throughout the city. The World Health Organization (WHO) was notified of the outbreak on December 31, 2019. The cases continued to spread outside of the area and then across the world. COVID-19 was reported as a global health emergency by the end of January 2020. As the worldwide case numbers increased, the WHO declared on March 11, 2020, that COVID-19 had reached the pandemic stage. The virus is now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease it causes is called coronavirus disease 2019 (COVID-19). In March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic.

Status of Vaccination Against Hepatitis B Among Dental Assistants of Multan
Overview:
Direct contact of dental health care workers (and doctors) with patients makes them prone to get infection with hepatitis B and other communicable disease. Dentists are profoundly at risk of getting infected from patient's saliva and blood. Stick Injuries with needle or other sharp instruments used during medical procedures and blood transfusion have the risk to transfer hepatitis B among the medicinal services specialists. It is important to prepare for safety measures to avoid cross infection with Hepatitis B.4 Dental assistants work closely with patients, under the guidance of a dental surgeon. It is an ethical duty of an employee to protect the patient and health care assistant from cross infection contamination.6 Immunization against Hepatitis B should be mandatory for every health care worker.
The objective of this study was to find out the status of vaccination against of Hepatitis B virus among dental assistants of Multan.
It was concluded that lack of motivation was the main reason for not receiving vaccination. Self-reported rate of hepatitis B vaccination among Dental Assistants of Multan was low. Lack of motivation was the main impediment.

COVID-2019 -A comprehensive pathology insight
Overview Corona virus disease-2019 (COVID-19) caused by severe acute respiratory syndrome corona virus-2 (SARS CoV- 2), a highly contagious single stranded RNA virus genetically related to SARS CoV. The lungs are the main organs affected leading to pneumonia and respiratory failure in severe cases that may need mechanical ventilation. Occasionally patient may present with gastro-intestinal, cardiac and neurologic symptoms with or without lung involvement. Pathologically, the lungs show either mild congestion and alveolar exudation or acute respiratory distress syndrome (ARDS) with hyaline membrane or histopathology of acute fibrinous organizing pneumonia (AFOP) that parallels disease severity. Other organs like liver and kidneys may be involved secondarily.
Currently the treatment is principally symptomatic and prevention by proper use of personal protective equipment and other measures is crucial to limit the spread. During the pandemic there is paucity of literature on pathological features including pathogenesis, hence in this review we provide the current pathology centred understanding of COVID-19. Furthermore, the pathogenetic pathway is pivotal in the development of therapeutic targets.

Prevalence of SARS-CoV-2 infection in general practitioners and nurses in primary care and nursing homes in the Healthcare Area of León and associated factors
Overview To evaluate the prevalence of and factors associated with SARS-CoV-2 infection in general practitioners and nurses from primary care centres and nursing homes in the Healthcare Area of León (Spain). The work centre, type of profession, COVID-19 infection, level of exposure, compliance with preventive measures, isolation (if required) and diagnostic tests carried out were collected. The determination of infection was made by differentiated rapid diagnostic test (dRDT), using a finger-stick whole-blood sample. The association of variables with infection was assessed by multivariable non-conditional logistic regression. No statistically significant differences were observed by sex, type of professional, level of exposure or compliance with preventive measures. The prevalence of SARS-CoV-2 infection in this group is low. A high number of professionals remain susceptible to SARS-CoV-2 infection and therefore protective measures should be taken, especially for professionals working in nursing homes.

Preventing infectious diseases for healthy ageing: The VITAL public-private partnership project
Overview Prevention of infectious diseases through immunisation of the growing ageing adult population is essential to improve healthy ageing. However, many licenced and recommended vaccines for this age group show signs of waning of the protective effect due to declining immune responses (immunosenescence) and decreasing vaccine uptake. Today’s major challenge is to improve vaccine effectiveness and uptake and to deploy efficient vaccination strategies for this age group. The Vaccines and Infectious diseases in the Ageing population (VITAL) project, with partners from 17 academic & research groups and public institutes as well as seven industry collaborators, aims to address this challenge. The ambition is to provide evidence-based knowledge to local decision makers. Using a holistic and multidisciplinary approach and novel analytical methods, VITAL will provide tools that allow the development of targeted immunisation programs for ageing adults in European countries. The project is based on four pillars focussing on the assessment of the burden of vaccine-preventable diseases in ageing adults, the dissection of the mechanisms underlying immuno-senescence, the analysis of the clinical and economic public health impact of vaccination strategies and the development of educational resources for healthcare professionals.

Ways in which healthcare interior environments are associated with perceived safety against infectious diseases and coping behaviours
Overview
Global pandemic outbreaks are a cause of fear. Healthcare workers (HCWs), especially those fighting the pathogens at the front line, are at higher risk of being infected while they treat patients. In addition, various environmental fomites in hospitals, which may carry infectious agents, can increase the risk of acquiring an infectious disease.
To deliver the best healthcare practice, it is critical that HCWs feel safe and protected against infectious diseases. The aim of this study was to improve understanding of HCWs’ hand hygiene (HH) behaviours and perceptions of infectious diseases from a psychological perspective.
This study found that an increase in the number of HH stations at convenient locations would increase HH compliance and perceived safety against infectious diseases among HCWs. In response to the current research gap in psychological aspects associated with HH, this study found that HCWs’ coping behaviours can be predicted by their perceived likelihood of contamination and perceived vulnerability.

Clinical Practice Guidelines: Fever and Sepsis
Overview
Feverish illness in young children usually indicates an underlying infection and is a cause of concern for parents and carers. Despite advances in healthcare, infections remain a leading cause of death in children under the age of 5 years. Fever in young children can be a diagnostic challenge for healthcare professionals because it is often difficult to identify the cause. In most cases, the illness is due to a self-limiting viral infection. However, fever may also be the presenting feature of serious bacterial infections such as meningitis and pneumonia. A significant number of children have no obvious cause of fever despite careful assessment. These children with fever without apparent source are of concern to healthcare professionals because it is especially difficult to distinguish between simple viral illnesses and life-threatening bacterial infections in this group.

Overview
Tuberculosis (TB) (see the image below), a multisystemic disease with myriad presentations and manifestations, is the most common cause of infectious disease–related mortality worldwide. Although TB rates are decreasing in the United States, the disease is becoming more common in many parts of the world. In addition, the prevalence of drug-resistant TB is increasing worldwide. Classic clinical features associated with active pulmonary TB in elderly individuals with TB may not display typical signs and symptoms. The absence of any significant physical findings does not exclude active TB. Classic symptoms are often absent in high-risk patients, particularly those who are immunocompromised or elderly. It is important to isolate patients with possible TB in a private room with negative pressure.

Overview The reported incidence of viral pneumonia (see the image below) has increased during the past decade. In part, this apparent increase simply reflects improved diagnostic techniques, but an actual increase appears to have also occurred. Depending on the virulence of the organism, as well as the age and comorbidities of the patient, viral pneumonia can vary from a mild, self-limited illness to a life-threatening disease. This course is divided into 3 parts covering the aspects of Pneumonia leading into the much dreaded COVID 19 The influenza viruses are the most common viral cause of pneumonia. Primary influenza pneumonia manifests with persistent symptoms of cough, sore throat, headache, myalgia, and malaise for more than three to five days. Respiratory syncytial virus (RSV) is the most frequent cause of lower respiratory tract infection in infants and children and the second most common viral cause of pneumonia in adults.
Parainfluenza virus (PIV) is second in importance only to RSV as a cause of lower respiratory tract disease in children and pneumonia and bronchiolitis in infants younger than 6 months. PIV pneumonia and bronchiolitis are caused primarily by the PIV-3 strain. The signs and symptoms include fever, cough, coryza, dyspnea with rales, and wheezing.

| | Malaria | Malaria
Overview Malaria is a potentially life-threatening disease caused by infection with Plasmodium protozoa transmitted by an infective female Anopheles mosquito. Patients with malaria typically become symptomatic a few weeks after infection, though the symptomatology and incubation period may vary, depending on host factors and the causative species. Most patients with malaria have no specific physical findings, but splenomegaly may be present. In patients with suspected malaria, obtaining a history of recent or remote travel to an endemic area is critical. Asking explicitly if they travelled to a tropical area at any time in their life may enhance recall. Maintain a high index of suspicion for malaria in any patient exhibiting any malarial symptoms and having a history of travel to endemic areas.
It is also important to determine the patient's immune status, age, and pregnancy status; allergies or other medical conditions that he or she may have; and medications that he or she may be using.

Evaluating Point-of-Care HIV Screening in Dental Hygiene Education Settings: Patient, Faculty, and Student Perspectives
Overview Although HIV screening is needed at a wider range of sites, dentists have shown reluctance to incorporate screening in their practices, but dental hygiene settings may be better suited for such screenings. The aim of this mixed-methods study was to determine the feasibility and acceptability of point-of-care (POC) HIV screening in dental hygiene education community settings from the patient, faculty, and student perspectives.
After training, dental hygiene students and faculty at a Canadian dental school offered POC HIV screening to patients as part of routine dental hygiene care over 36 weeks at four sites in 2015-16. Of the 199 patients offered screening, 78 agreed; no positive results were found. Of the 199 patients, 97 completed an 11-item survey (49% response rate), with 80 (82%) agreeing HIV screening was within the scope of practice of a dental professional.
Of the 57 patients who were screened, 48 (84%) agreed POC HIV screening should be part of regular dental check-ups, and 52 (91%) perceived dental settings were appropriate sites for screening. The main reasons for patients’ agreeing to screening were that it was free and convenient, and the results were delivered quickly. Those who refused screening had been tested recently or did not perceive themselves at risk for HIV. In two focus groups with 12 dental hygiene students, one focus group with five faculty members, and individual interviews with five other faculty members, participants agreed on the importance of offering POC HIV screening in the dental setting as a public health service. Faculty members thought students were well prepared and increased in confidence with testing. Students expressed a desire to offer screening throughout their careers and to educate patients about the importance of HIV testing.

A modified anthrax toxin-based enzyme linked immunospot assay reveals robust T cell responses in symptomatic and asymptomatic Ebola virus exposed individuals
Overview
Ebola virus (EBOV) caused more than 11,000 deaths during the 2013 ± 2016 epidemic in West Africa without approved vaccines or immunotherapeutic. Despite its high lethality in some individuals, EBOV infection can produce little to no symptoms in others. A better understanding of the immune responses in individuals who experienced minimally symptomatic and asymptomatic infection could aid the development of more effective vaccines and antivirals against EBOV and related filoviruses.
The West African Ebola virus (EBOV) outbreak is the largest on record with over 28,000 reported symptomatic cases and more than 11,000 deaths. We developed a simple and inexpensive modified anthrax toxin based ELISPOT assay to detect and characterize the T cell responses elicited by prior exposure to EBOV. Our data show robust T cell responses to several EBOV proteins in individuals who experienced both severe and asymptomatic EBOV infections. These results provide further evidence that EBOV transmission events can go undetected. We also show that the seropositive asymptomatic individuals have stronger T cell responses compared to survivors, which has important implications for vaccine development.

Evidence for increasing densities and geographic ranges of tick species of public health significance other than Ixodes scapularis in Quebec, Canada
Overview
Climate change is driving emergence and establishment of Ixodes scapularis, the main vector of Lyme disease in QueÂbec, Canada. As for the black-legged tick, I. scapularis Say, global warming may also favor northward expansion of other species of medically important ticks. The aims of this study were to determine (1) current diversity and abundance of ticks of public health significance other than I. scapularis, (2) sex and age of the human population bitten by these ticks (3), and the seasonal and geographic pattern of their occurrence.
Of the 862 people bitten by these ticks, 43.3% were I. cookei ticks removed from children aged < 10 years. These findings demonstrate the need for surveillance of all the tick species of medical importance in QueÂbec, particularly because climate may increase their abundance and geographic ranges, increasing the risk to the public of the diseases they transmit.

Simultaneous Detection of Key Bacterial Pathogens Related to Pneumonia and Meningitis Using Multiplex PCR Coupled With Mass Spectrometry
Overview
Pneumonia and meningitis continue to present an enormous public health burden and pose a major threat to young children. Among the causative organisms of pneumonia and meningitis, bacteria are the most common causes of serious disease and deaths. It is challenging to accurately and rapidly identify these agents.
Using the BP-MS method, we could accurately identify the expected bacteria without cross-reactivity with other pathogens. For the 11 target bacterial pathogens, the analytical sensitivity of the BP-MS method was as low as 10 copies/reaction. To further evaluate the clinical effectiveness of this method, 204 nasopharyngeal swabs from hospitalized children with suspected pneumonia were tested using this method.
We used real-time PCR and nested PCR to confirm positive results, with identical results obtained for 81.4% (136/167) of the samples. The BP-MS method is a sensitive and specific molecular detection technique in a multiplex format and with high sample throughput. Therefore, it will be a powerful tool for pathogen screening and antibiotic selection at an early stage of disease.

Community perspectives on HIV, violence and health surveillance in rural South Africa: a participatory pilot study
Overview
South Africa faces a complex burden of disease consisting of infectious and non–communicable conditions, injury and interpersonal violence, and maternal and child mortality. Inequalities in income and opportunity push disease burdens towards vulnerable populations, a situation to which the health system struggles to respond. There is an urgent need for health planning to account for the needs of marginalized groups in this context. Objectives were to develop a process to elicit the perspectives of local communities in the established Agincourt health and socio-demographic surveillance site (HDSS) in rural north–east South Africa on two leading causes of death: HIV/AIDS and violent assault, and on health surveillance as a means to generate information on health in the locality.
The groups identified a range of social and health systems issues including risky sexual health behaviors, entrenched traditional practices, alcohol and substance abuse, unstable relationships, and debt as causative. Participants also explained how compromised patient confidentiality in clinics, insensitive staff, and a biased judicial system were problematic for the treatment and reporting of both conditions. The discussions provided information not available from other sources on the social and health systems processes through which access to good quality health care is constrained in this setting.

QTc interval prolongation during favipiravir therapy in an Ebolavirus-infected patient
Overview
Life-threatening arrhythmia may be induced by corrected QT (QTc) interval prolongation. Several antimicrobial drugs have been associated with QTc interval prolongation. Favipiravir is an inhibitor of the RNA-dependent RNA polymerase of many RNA viruses, including influenza viruses, arenaviruses, phleboviruses, hantaviruses, flaviviruses, enteroviruses, and noroviruses. Favipiravir has also been used in the recent epidemic of Ebolavirus (EBOV) in West Africa. To date, no significant effects of favipiravir on the QT/QTc interval have been detected. We report a case of QTc interval prolongation during favipiravir therapy in an EBOV-infected patient treated at our institution.
In conclusion, we suggest that favipiravir administered at high doses, together with the cofactors discussed above, may have contributed to inducing a QTc interval prolongation in our EBOV patient. If feasible, ECG monitoring could be advisable during high-dose favipiravir therapy, especially when patients experience electrolyte disturbances and concomitant use of drugs with QTc-prolonging potential. Encephalitis or central nervous system (CNS) pathology may have a role in prolonging QT interval. Acknowledgement

Ebolaviruses: New roles for old proteins
Overview
In 2014, the world witnessed the largest Ebolavirus outbreak in recorded history. The subsequent humanitarian effort spurred extensive research, significantly enhancing our understanding of ebolavirus replication and pathogenicity. The main functions of each ebolavirus protein have been studied extensively since the discovery of the virus in 1976; however, the recent expansion of ebolavirus research has led to the discovery of new protein functions. The international containment effort spurred extensive research that is enhancing.
These newly discovered roles are revealing new mechanisms of virus replication and pathogenicity, whilst enhancing our understanding of the broad functions of each ebolavirus viral protein (VP). Many of these new functions appear to be unrelated to the protein's primary function during virus replication. Such new functions range from bystander T-lymphocyte death caused by VP40-secreted exosomes to new roles for VP24 in viral particle formation. This review highlights the newly discovered roles of ebolavirus proteins in order to provide a more encompassing view of ebolavirus replication and pathogenicity.

Overview
Gastrointestinal (GI) bleeding is a leading cause of death in dengue. This study aims to identify predictors for GI bleeding in adult dengue patients, emphasizing the impact of existing co-morbid disease(s). Of 1300 adults with dengue virus infection, 175 (mean age, 56.5±13.7 years) patients with GI bleeding and 1,125 (mean age, 49.2±15.6 years) without GI bleeding (controls) were retrospectively analyzed.
Our study is the first to disclose that end stage renal disease and previous stroke, with additional co-morbidities, were strongly significant associated with the risk of GI bleeding in patients with dengue virus infection. Identification of these risk factors can be incorporated into the patient assessment and management protocol of dengue virus infection to reduce its mortality. Our study emphasizes that, in addition to older age and thrombocytopenia , end stage renal disease and previous stroke, with additional co-morbidities, are important clinical predictor of GI bleeding in adult patients with DENV infection. More studies, particularly prospective studies are required to validate these findings for better generalization of their clinical utility.

Structure and assembly of the Ebola virus nucleocapsid
Overview
Ebola and Marburg viruses are filoviruses: filamentous, enveloped viruses that cause haemorrhagic fever1. Filoviruses are within the order Mononegavirales2 which also includes rabies virus, measles virus, and respiratory syncytial virus. Mononegaviruses have non-segmented, single-stranded negative-sense RNA genomes that are encapsidated by nucleoprotein (NP) and other viral proteins to form a helical nucleocapsid (NC). NC acts as a scaffold for virus assembly and as a template for genome transcription and replication. Insights into NP-NP interactions have been derived from structural studies of oligomerized, RNA-encapsidating NP3–6 and cryo-electron microscopy (cryo-EM) of NC7–12 or NC-like structures11–13. There have been no high-resolution reconstructions of complete mononegavirus NCs.
Here, we have applied cryo-electron tomography and sub-tomogram averaging to determine the structure of Ebola virus NC within intact viruses and recombinant NC-like assemblies. These structures reveal the identity and arrangement of the NC components, and suggest that the formation of an extended alpha-helix from the disordered C-terminal region of NP-core links NP oligomerization, NC condensation, RNA encapsidation, and accessory protein recruitment.

Establishing Ebola Virus Disease (EVD) diagnostics using GeneXpert technology at a mobile laboratory in Liberia: Impact on outbreak response, case management and laboratory systems strengthening Overview
The 2014-16 Ebola Virus Disease (EVD) outbreak in West Africa highlighted the necessity for readily available, accurate and rapid diagnostics. The magnitude of the outbreak and the re-emergence of clusters of EVD cases following the declaration of interrupted transmission in Liberia, reinforced the need for sustained diagnostics to support surveillance and emergency preparedness. We describe implementation of the Xpert Ebola Assay, a rapid molecular diagnostic test run on the GeneXpert platform, and the subsequent impact on EVD outbreak response, case management and laboratory system strengthening.
During the 18 months of operation, the laboratory tested a total of 9,063 blood specimens, including 21 EVD positives from six confirmed cases during two outbreaks. Collaboration between surveillance and laboratory coordination teams during this and a later outbreak in March 2016, facilitated timely and targeted response interventions. This model of a mobile laboratory equipped with Xpert Ebola test, staffed by local laboratory technicians, could serve to strengthen outbreak preparedness and response for future outbreaks of EVD in Liberia and the region.

Characterization of Influenza Virus Pseudotyped with Ebolavirus Glycoprotein
Overview
We have produced a new Ebola virus pseudotype, E-S-FLU, that can be handled in biosafety level 1/2 containment for laboratory analysis. The E-SFLU virus is a single-cycle influenza virus coated with Ebolavirus glycoprotein, and it encodes enhanced green fluorescence protein as a reporter that replaces the influenza virus hemagglutinin. Infection of cells with the E-S-FLU virus was dependent on the Niemann-Pick C1 protein, which is the well-characterized receptor for Ebola virus entry at the late endosome/lysosome membrane. The E-S-FLU virus was neutralized specifically by an anti-Ebolavirus glycoprotein antibody and a variety of small drug molecules that are known to inhibit the entry of wild-type Ebola virus.
To demonstrate the application of this new Ebola virus pseudotype, we show that a single laboratory batch was sufficient to screen a library of 1,280 pharmacologically active compounds for inhibition of virus entry. The E-S-FLU virus is a new tool for Ebola virus cell entry studies and is easily applied to high throughput screening assays for small-molecule inhibitors or antibodies. Acknowledgement

Soil-transmitted helminth infection, loss of education and cognitive impairment in school-aged children: systematic review
Overview
Cardiovascular evidence of an adverse influence of soil transmitted helminth (STH) infections on cognitive function and educational loss is equivocal. Prior meta-analyses have focused on randomized controlled trials only and have not sufficiently explored the potential for disparate influence of STH infection by cognitive domain. We re-examine the hypothesis that STH infection is associated with cognitive deficit and educational loss using data from all primary epidemiologic studies published since 2016. Cognitive function was defined in four domains (learning, memory, reaction time and innate intelligence) and educational loss in two domains (attendance and scholastic achievement). Sub-group analyses were implemented by study design, risk of bias (ROB) and co-prevalence of Schistosoma species infection. Influential studies were excluded in sensitivity analysis to examine stability of pooled estimates. Despite the empirical debate regarding the cognitive benefit of de-worming for STH, the current ethical, clinical and health policy environments remain strongly skewed in favor of de-worming for child growth, prevention of anaemia and potentially avoidance of preventable cognitive deficits

Ebola Virus Disease: Clinical Review.
Overview
Ebola transmission may occur as a result of close contact with body fluids of infected patients. The incubation period for Ebola after infection is said to be 5-9 days, with a range of 1-21 days in 95% or more of patients,2 3 with the patients not considered infectious until they develop symptoms.
This article is therefore a clinical review whose objective is to investigate what makes the differential diagnosis of Ebola broad. This article therefore examines the causes of the Ebola virus as we as the pathophysiology of this infection. This article equally went further to examine the infection prevention and control measures are used to curb the spread of Ebola from one country to another.
The hypothesis here was that there is high likelihood of infected people travelling, thus, all countries are expected to have tested and practiced protocols ready for screening and managing Ebola patients. Of course the article also outlined some of the clinical features as well as the symptoms of the virus.

Synergies, tensions and challenges in HIV Prevention, treatment and cure research.
OVERVIEW
The ethical concerns associated with HIV prevention and treatment research have been widely explored in South Africa over the past 3 decades. Because HIV cure research is relatively new to the region, significant ethical and social challenges are anticipated.
In-depth interviews were conducted on a purposive sample of fourteen key informants in South Africa. Audiotaped interviews were transcribed verbatim with concurrent thematic analysis. The perspectives of HIV clinicians, researchers and activists were captured.
Participants described a symbiotic relationship between cure, treatment and prevention research necessitating collaboration. Assessing and managing knowledge and expectations around HIV cure research emerged as a central theme related to challenges to constructing ‘cure’ - how patients understand the idea of cure is important in explaining the complexity of cure research especially in the South African context where understanding of science is often challenging.
It was encouraging to note the desire for synergy amongst researchers and clinicians working in the fields of prevention, treatment and cure. Translation of complex HIV cure science into lay language is critical. It is hoped that knowledge and resource sharing in the context of collaboration between research scientists working in cure and those working in treatment and prevention will accelerate progress towards cure.
