The article discusses research that examined the association of hepatitis E virus (HEV) prevalence with HIV infection in sub-Saharan Africa, focusing on pregnant Malawian women. Topics covered include the seroprevalence of hepatitis E during pregnancy, the rate of new HEV infections 2 years after delivery, and HEV prevalence in HIV-exposed children in the endemic area.

To avoid overdiagnosis, accuracy in the identification of true malaria cases is of critical importance. Samples (either whole blood, dried blood spots or plasma/serum) collected at the time of clinically diagnosed malaria episodes in a cohort of Malawian HIV-infected mothers and their children were retrospectively tested with the enzyme-linked immunosorbent assay (ELISA) for HRP-2 (histidine- rich protein 2) detection. There were 55 and 56 clinically diagnosed cases of malaria in mothers and children, respectively, with samples available for testing. Rates of laboratory-confirmed episodes were 20% (11 of 55) in mothers and 16.1% (9 of 56) in children. Hemoglobin was lower in children with confirmed malaria compared to those with clinical malaria diagnosis. The results of our study support the widespread use of rapid diagnostic tests.
