Malaria and COVID-19 prevalence in a population of febrile children and adolescents living in Libreville.

Background: Patients with acute febrile illness need to be screened for malaria and coronavirus disease 2019 (COVID-19) in malaria-endemic areas to reduce malaria mortality rates and to prevent the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Objectives: To estimate the frequency of children and adolescents with COVID-19 and/or malaria among febrile patients attending for malaria diagnosis.

Method: This cross-sectional study was conducted in a sentinel site for malaria surveillance during the SARS-CoV-2 pandemic (Omicron variant), from October 2021 to December 2021 in Gabon.

Variations of Glossina sp. and trypanosome species frequency within different habitats in a sleeping sickness focus, Gabon.

Introduction: Knowledge of the infectious status of the Glossina is an indicator of risk of resurgence of Human African Trypanosomiasis (HAT). Environmental conditions have an impact on the density and diversity of both vector and Trypanosoma. The aim of the study was to determine the diversity and the infection rate of Glossina as well as the diversity of trypanosome species within habitats of an old HAT focus, in Gabon.
