Jan 18th, 2023 - In a Policy Forum piece, Dr. Nicola Low and colleagues define the research agenda for Mpox virus and transmission through sexual contact.

Dec 1st, 2022 - Despite reports of confirmed human infection following ocular exposure with both influenza A virus (IAV) and SARS-CoV-2, the dynamics of virus spread throughout oculonasal tissues and the relative capacity of virus transmission following ocular inoculation remain poorly understood. Furthermore, the impact of exposure route on subsequent release of airborne viral particles into the air has not b...

Dec 1st, 2022 - Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the acute respiratory disease coronavirus disease 2019 (COVID-19), which has resulted in millions of deaths globally. Here, we explored the mechanism of host cell entry of a luciferase-ZsGreen spike (SARS-CoV-2)-pseudotyped lentivirus using zebrafish embryos/larvae as an in vivo model. Successful pseudovirus ...

Nov 11th, 2022 - The Ebola Virus Disease (EVD) remains a global public health concern with multiple outbreaks over the last five years. This scoping review aimed to synthesize the current state of knowledge on awareness, education, and community mobilization programs on EVD prevention. A comprehensive search strategy was executed in October 2021 across eight databases (APA PsycInfo, CINAHL, Cochrane CENTRAL, Em...

Nov 9th, 2022 - Carbapenemase-producing Enterobacterales (CPE) is an increasing public health concern; these bacteria are highly transmissible in hospital environments and the number of patients with these multidrug-resistant bacteria is rising. Healthcare workers caring for patients colonized with CPE offer insight into care delivery and processes in the hospital setting. The aim of this review was to explore...

Nov 8th, 2022 - Influenza is responsible for more than 5 million severe cases and 290,000 to 650,000 deaths every year worldwide. Developing countries account for 99% of influenza deaths in children under 5 years of age. This paper aimed to determine the dynamics of influenza viruses in African transmission areas to identify regional seasonality for appropriate decision-making and the development of regional p...

Nov 8th, 2022 - Children requiring multiple blood transfusions are at high risk of transfusion-transmissible infections (TTIs). Lao People's Democratic Republic is a low-resource setting where donor blood screening faces challenges. This study aimed to determine the burden of TTIs in children in Vientiane Capital. 300 children with transfusion history and 300 controls were recruited. In addition, 49 newly diag...

Nov 2nd, 2022 - Influenza A viruses (FLUAV) cause respiratory diseases in many host species, including humans and pigs. The spillover of FLUAV between swine and humans has been a concern for both public health and the swine industry. With the emergence of the triple reassortant internal gene (TRIG) constellation, establishment of human-origin FLUAVs in pigs has become more common, leading to increased viral di...

Nov 1st, 2022 - Background: Bat flies (Diptera: Hippoboscoidea: Nycteribiidae and Streblidae) are increasingly appreciated as hosts of "bat-associated" viruses. We studied straw-colored fruit bats (Eidolon helvum) and their nycteribiid bat flies (Cyclopodia greefi) in Nigeria to investigate the role of bat flies in vectoring or maintaining viruses. Methods: We captured bats and bat flies across northern Nigeri...

Oct 21st, 2022 - Coronavirus disease 2019 (COVID-19) asymptomatic cases are hard to identify, impeding transmissibility estimation. The value of COVID-19 transmissibility is worth further elucidation for key assumptions in further modelling studies. Through a population-based surveillance network, we collected data on 1342 confirmed cases with a 90-days follow-up for all asymptomatic cases. An age-stratified co...

Oct 21st, 2022 - Given the increasing frequency of infections due to extended-spectrum β-lactamase (EBSL)-producing Klebsiella pneumoniae in humans over recent decades, infection control against this pathogen is of high importance. In this study, the transmission mode of ESBL-producing K. pneumoniae in neonatal intensive care units (NICU) was investigated. We collected K. pneumoniae isolates from patients admit...

Oct 15th, 2022 - Hospital transmission of SARS-CoV-2 has proved difficult to control, with healthcare-associated infections troublesome throughout. To understand factors contributing to hospital transmission of infections, which is necessary for containing spread. An outbreak of 56 staff and patient cases of COVID-19 over a 31-day period in a tertiary referral unit is presented, with at least a further 29 cases...

Oct 12th, 2022 - Elimination of hepatitis B virus (HBV) is a striking challenge for countries with high or moderate disease burden. Therefore, using China as a practical case to share experiences for similar countries may accelerate the achievement of the WHO 2030 target of 90% reduction in HBV-related incidence. We aim to evaluate the impact of national HBV immunization strategies in China; and the feasibility...

Oct 10th, 2022 - Interleukin (IL)-1β is a key innate cytokine that is essential for immune activation and promoting the inflammatory process. However, abnormal elevation in IL-1β levels has been associated with unwanted clinical outcomes. IL-1β is the most extensively studied cytokine among the IL-1 family of cytokines and its role in pathology is well established. During the course of human immunodeficiency vi...

Sep 30th, 2022 - Hepatitis A is a vaccine-preventable disease typically acquired through fecal-oral transmission. Hepatitis A virus (HAV) infection rates in the United States declined approximately 97% during 1995-2015 after the introduction and widespread pediatric use of hepatitis A vaccines (1). Since 2016, hepatitis A outbreaks have been reported in 37 states, involving approximately 44,650 cases, 27,250 ho...
