Pregnant women who are infected with the Human Immunodeficiency Virus (HIV) are particularly vulnerable to severe and recurrent infections with Human Herpesvirus 2 (HHV-2). Neonatal transmission of HHV-2 has been associated with malformations and neurological sequelae in infants, which makes it very important to perform antenatal monitoring for genital herpes. In the study, 134 pregnant women infected with HIV were tested for HHV-2 IgM and IgG using an enzyme-linked immunosorbent assay (ELISA) and had HHV-2 DNA analyzed by Real Time Polymerase Chain Reaction (qPCR). Fisher's exact test was applied to analyze the epidemiological dates (p < 0.05). A total of 59.7% of the pregnant women infected with HIV had HHV-2 IgG and 3.75% of them showed HHV-2 viremia. HHV-2 IgM was found in 6% of the pregnant women and 25% of them had HHV-2 viremia. The risk factors associated with HHV-2 seropositive were age under 20 and a CD4/CD8 ratio > 1. Our study found high HHV-2/HIV coinfection prevalence and HHV-2 viremia among patients with recurrent and primary genital infection, reinforcing the need of prevention and control of HHV-2 infection in order to avoid this virus transmission.
