Spatio-temporal distribution of HIV-tuberculosis coinfection in brazilian macroregions, between 2003 and 2016

Tuberculosis (TB) remains a serious global health problem. Brazil is among the 22 countries prioritized by WHO (World Health Organization), occupying 20th position country with the highest rates of TB, and the 19th TB-HIV coinfection rates. This study aimed to analyze the spatio-temporal distribution of TB-HIV coinfection, in accordance with the rates of incidence and prevalence, and proportion of deaths by tuberculosis coinfected individuals in five regions of Brazil. It was an ecological study of spatial-temporal distribution, using secondary data from individuals notified by TB/HIV, over the age of 15 years, between 2003 and 2016. The identification of spatial-temporal clusters was performed by ArcGis 10.1, developed by ESRI. A total of 81.101 new cases of TB/HIV coinfection were reported, with an average of 8,29% of coinfection in patients with tuberculosis, having highest average incidence in the southern region (6.26 cases/100,000 inhabitants.), and the lowest in the mid-west region (2,53). The average incidence rate in Brazil was 3,7 cases/100.000 hab. Regarding the proportions of death, the highest average occurred in northern region with 5,9 deaths per 100 individuals coinfected, and the southern region showed the lowest proportion of death (2,36). In Brazil the average proportion of deaths was 4 per 100 patients coinfected. It is concluded that high incidence rates were identified, with a high proportion of deaths among people with TB-HIV showing differences between Brazilian regions, demonstrating the importance of national and regional programmers for the control of tuberculosis and HIV/AIDS and public health policies for reduction of cases.
