Abstract

Objective: To analyze the temporal trend and spatial distribution of HIV mother-to-children transmission in Santa Catarina, 2007-2017. Methods: Mixed ecological study with data from the Notifiable Diseases Information System. Linear regression was performed for time series analysis and the mean rates in the period and annual mean percentage changes in the rates of HIV-infected pregnant women were calculated; of children exposed to HIV during pregnancy; and seroconversion of children exposed to HIV/AIDS during pregnancy, in addition to data geoprocessing. Results: There were 5,554 pregnant women living with HIV, with a rate of 5.6 pregnant infected. The mean seroconversion rate was 13.5/100,000 live births (95%CI 6.8;20.1) and showed a decreasing trend (APC=-99.4%; 95%CI-99.9;-93.1). The seroconversion rate was more expressive in small towns. Conclusion: The rate of HIV-infected pregnant women was stable in the period, whereas the number of children infected with HIV by vertical transmission decreased.
