✦ Synopsis

Abstract

The feasibility and implications of the use of the polymerase chain reaction (PCR) assay in studies of HIV1 mother to child transmission in Africa were investigated. Uncultured leukocyte blood cells (PBL) obtained in Brazzaville (Congo) from newborns and infants (mean age = 27 weeks) of infected mothers were tested. HIV1 DNA sequences were identified in the PBL of six of eight newborns and 14 of 23 babies born to HIV1‐positive mothers. In addition two of four babies, who at birth had been seropositive and subsequently were seronegative, were HIV1 DNA positive by PCR. This study demonstrates directly, therefore, a high rate of HIV1 transmission in Africa; it also indicates that PCR should be used for such epidemiological studies.
