Prevalencia y diagnóstico temprano del virus de inmunodeficiencia humana por transmisión vertical durante el periodo 2015-2016 en la Región Sanitaria VI de la Provincia de Buenos Aires

Vertical transmission is a relevant pathway for the acquisition of human immunodeficiency virus (HIV) infection. This can occur during pregnancy, at the time of delivery, or during breastfeeding. All newborns born to seropositive mothers have IgG antibodies, which are received through the placenta and remain in their blood for 18 months of life, not involving infection, and the diagnosis must be made through the analysis of viral particles. The effectiveness of vertical transmission depends on several factors, the most important being the amount of virus circulating in the maternal blood. According to the Office of AIDS and Sexually Transmitted Diseases of Argentina (DSyETS), HIV transmission should be diagnosed early (at the time of the first sample) for immediate therapeutic application and prevention of the disease. Objective: To determine the prevalence of vertical transmission of HIV during the 2015-2016 period and to evaluate the adherence to the time of sampling of the first sample in the diagnosis, as recommended by the DSyETS, with the aim to improve the early diagnosis of vertical transmission. Results and conclusions: The vertical HIV transmission rate obtained during the period evaluated was 6.38 %, with an increase in HIV transmission in 2016 (11.11%) compared to 2015 (4.48%). Results also showed that 12.77 % of newborns born to HIV-positive mothers were studied to diagnose vertical HIV transmission within 72 hours of life, 26.60 % before 30 days of life, and 60.64 % after one month of life. The percentage of newborns diagnosed early is expected to increase,
