Molecular surveillance of Plasmodium falciparum histidine-rich protein 2/3 gene deletions in Mozambique, 2023.

Background: Rapid diagnostic tests (RDTs) based on the detection of Plasmodium falciparum histidine rich protein 2 (PfHRP2) are widely used for the diagnostic of P. falciparum in Africa. However, deletions of the pfhrp2 and pfhrp3 genes can lead to false negative test results and compromise appropriate case management.

High SARS-CoV-2 Exposure in Rural Southern Mozambique After Four Waves of COVID-19: Community-Based Seroepidemiological Surveys.

Background: Mozambique was one of many African countries with limited testing capacity for SARS-CoV-2. Serosurveys, an alternative to estimate the real exposure to understand the epidemiology and transmission dynamics, have been scarce in Mozambique. Herein, we aimed to estimate the age-specific seroprevalence of SARS-CoV-2 in the general population of the Manhiça District, at four time points, for evaluating dynamics of exposure and the impact of vaccination.
