High level of HIV false positives using EIA-based algorithm in survey: Importance of confirmatory testing.

The Mozambique Indicators of Immunization, Malaria and HIV/AIDS (IMASIDA) survey was conducted in 2015 and used a two Enzyme Immunoassay (EIA) (Vironostika HIV-1/2 and Murex HIV-1/2) based algorithm to determine the HIV status of the consented participants. The Mozambique Ministry of Health, with support from the US Centers for Disease Control and Prevention (US CDC), added Bio-Rad Geenius™ HIV-1/2 Supplemental Assay to the IMASIDA HIV testing algorithm to confirm all specimens that were found to be reactive on one or both EIAs. In total 11690 specimens were collected to estimate the proportion of HIV positive samples.

High Burden of HIV Infection and Risk Behaviors Among Female Sex Workers in Three Main Urban Areas of Mozambique.

This is the first integrated biological and behavioral survey among female sex workers (FSW) in Mozambique. Using respondent-driven sampling, 400, 411 and 429 FSW were enrolled respectively in Maputo, Beira and Nampula in 2011-2012. Estimates were produced using RDSAT 7.

Serologic and molecular typing of human T-lymphotropic virus among blood donors in Maputo City, Mozambique.

Background: Screening for human T-lymphotropic virus-1/2 (HTLV-1/2) infection is not performed in blood banks in Mozambique. The aim was to determine the prevalence of HTLV-1/2 among blood donors of the Maputo Central Hospital Blood Bank and measure the coinfection rate of HTLV-1/2 with human immunodeficiency virus (HIV), hepatitis B virus (HBV), and syphilis.

Study Design And Methods: A total of 2019 consecutive blood donors were screened for HTLV-1/2 antibodies, HIV-1/2 antibodies, hepatitis B surface antigen (HBsAg), and rapid plasma reagin (RPR) for syphilis.
