Great efforts have been made in the last few years in order to implement the prevention of mother-to-child transmission (PMTCT) program in Equatorial Guinea (GQ). The aim of this study was to evaluate the rates of mother-to-child HIV transmission based on an HIV early infant diagnosis (EID) program.


A prospective observational study was performed in the Regional Hospital of Bata and Primary Health Care Centre Maria Rafols, Bata, GQ. Epidemiological, clinical, and microbiological characteristics of HIV-1-infected mothers and their exposed infants were recorded. Dried blood spots (DBS) for HIV-1 EID were collected from November 2012 to December 2013. HIV-1 genome was detected using Siemens VERSANT HIV-1 RNA 1.0 kPCR assay.


Sixty nine pairs of women and infants were included. Sixty women (88.2%) had WHO clinical stage 1. Forty seven women (69.2%) were on antiretroviral treatment during pregnancy. Forty five infants (66.1%) received postnatal antiretroviral prophylaxis. Age at first DBS analysis was 2.4 months (IQR 1.2-4.9). One infant died before a HIV-1 diagnosis could be ruled out. Two infants were HIV-1 infected and started HAART before any symptoms were observed. The rate of HIV-1 transmission observed was 2.9% (95%CI 0.2-10.5).


The PMTCT rate was evaluated for the first time in GQ based on EID. EID is the key for early initiation of antiretroviral therapy and to reduce the mortality associated with HIV infection.
