Molecular surveillance of hepatitis E virus in wastewater in Yaoundé, Cameroon.

Background: Hepatitis E virus (HEV) is a zoonotic pathogen mainly transmitted through contaminated food or water in sub-Saharan countries, highlighting the need for environmental surveillance. This study aimed to assess the burden and molecular characterization of HEV in environmental wastewater.

Method: A community-based surveillance was conducted in Yaoundé, Cameroon, using untreated wastewater samples collected monthly from January to December 2023 from hospitals, residential sewage systems, markets, and plant watering points.

First molecular detection of five gastroenteritis viruses in untreated wastewater and impact of seasonal change on their distribution in Cameroon.

Background: Wastewater-based epidemiology has emerged as a valuable tool for surveilling food- and waterborne disease outbreaks. However, wastewater-based epidemiology remains poorly understood in sub-Saharan Africa. The current study investigated the prevalence of five human enteric viruses and the effect of seasonality on their distribution.

Seroprevalence of SARS-CoV-2 antibodies and associated risk factors during the second wave of infection in a university community in Cameroon.

Background: The COVID-19 pandemic has caused a public health emergency in all sectors of society, including universities and other academic institutions in Cameroon. However, little is known concerning the real prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections among student communities during the second wave of infection in Cameroon. This study aimed to estimate SARS-CoV-2 antibodies seroprevalence among participants in a university community in Cameroon.
