Abstract

In many developing countries, mothers' awareness remains a challenge despite the scaling up of antenatal care and programs preventing mother-to-child (MTC) HIV transmission. The present study was done in Libreville, Gabon where all antenatal care (delivery included) is free of charge. Here we assessed the timing of antenatal antiretroviral (ARV) prophylaxis initiation, HIV-exposed infants' age at their first postnatal HIV check visit and investigated the association between mothers' awareness or knowledge on their ARV therapy and infants' HIV infection. We interviewed HIV-positive mothers on their first and subsequent laboratory visits to investigate infants' HIV status and tested infants for HIV RNA and antibody between 2012 and 2014. We established that (1) of 718 HIV-positive mothers, only 6% were fully aware and knew what ARV treatment they were on during pregnancy; (2) half of the women (54%) start their antenatal ARV prophylaxis initiation during the second trimester of pregnancy; (3) 64% of HIV-exposed infants had their first HIV infection screening between birth and three months of age; (4) the overall prevalence of HIV infection in infants born from infected mothers was 8.9%; and (5) infants born from mothers uncertain about taking prophylactic ARV therapy were 13.3 times more likely to be infected by HIV than infants born from mothers certain about taking prophylactic ARV therapy. In conclusion, the study showed that despite free antenatal care, early access and adherence to components of MTC, HIV transmission preventive care remains unsatisfactory.
