Background: For the last 5 years UNAIDS reports no reduction in new HIV infections in Latin America (LA) remarking an insufficient advance to the aim to significantly reduce HIV transmission by 2020. Nevertheless, the report shows marked disparities among countries and in many cases lack of data. The objective of our study was to monitor the trends of HIV epidemics in LA by independent data collection of number and demographic characteristics of new cases admitted to care from 2013 to 2017.
Methods: We collected data from 42 public and private HIV centers from capital cities and provinces in 42 HIV Care Centers from 11 countries in LA. All selected centers reported complete data from 2013 to 2017. Gender, age and CD4 at admission among other baseline characteristics were registered. Transfers in from other centers were excluded of the analysis. Ponderation was made by type of center; RT, OR and heterogeneity by MCMC and GLMER
Results: 48,179 new cases were admitted in 5 years increasing from 7,271 in 2013 to 11,945 in 2017. Women represented 21.7% of new cases in 2013 decreasing to a 16.9% in 2017. Distribution by age in new cases in women remained stable along time but presentation to care at younger ages steadily increased among men during in the 5 years reported. In 2013 34.5% of new cases in men were younger than 29 years old. By 2017 this group of age represented 46.7% of new cases as shown in Graph 1.
Conclusions: Our data in a representative sample of 11 LA countries show a significant increase in HIV transmission among young men in LA and should be taken as an alert to urgently intensify prevention strategies in this principal key population in LA. Unprotected sexual practices in young men should be focused as a priority for prevention strategies.
