HIV infection can be acquired through perinatal transmission. The risk of acquiring this infection has been increased in recent years because the epidemic has taken a heterosexual pattern, which has caused a growth in the number of infected women and a potential risk for perinatal transmission. Objective: To determine the risk factors associated with vertical transmission in newborns to HIV-positive mothers at the Care Center for Patients with Sexually Transmitted Infections and AIDS (CAPACITS) in Veracruz, Mexico. Material and methods: We conducted a retrospective cohort study of a population of HIV-positive mothers and their newborns, who sought care at the CAPACITS of Veracruz between 2007 and 2012. The records of controlled mothers and their children were analyzed using descriptive and inferential statistics. Results: The study was performed in 50 women. The variables studied were: associated factors in mothers and associated factors in newborns. Concerning the antiretroviral treatment in the sample of mothers, nine (18%) did not take any treatment; two of their children became infected. In the case of treated mothers, none of their children became infected. Considering the infection-related variables in the product, the main factor for the spread of the infection to the children was a mother without treatment schedule and, in second place, a CD4 count < 200 cells/mm³. Conclusions: The results of our study predict that the positivity of the newborn depends on the maternal antiretroviral treatment.
