Abstract

Objective: To assess actions directed toward prevention of vertical transmission of HIV. Methods: Epidemiological and documental study with 1,364 seropositive pregnant women notified in the Notifiable Diseases Information System over ten years.

Results: The number of notified cases of seropositive pregnant women increased during the 10-year period; 41.72% of women used antiretroviral therapy in the prenatal period and 84.53% of women did prenatal care The prevalence of cesarean delivery was 63.12%; 67.01% of parturients used antiretroviral during labor and 71.48% of children started therapy within the first 24 hours of life. Conclusion: Actions directed toward prevention of vertical transmission of HIV are partly effective because less than the half of infected pregnant women used antiretroviral therapy in the prenatal period.
