HIV/AIDS epidemic in a western border municipality of Rio Grande do Sul, Brazil: evolution, HIV cascade of care and lethality

Abstract

Objective: To analyze the characteristics and trends of HIV/AIDS epidemic in Uruguaiana, Rio Grande do Sul, between 2005 and 2015 through indicators related to infection and the cascade of care of people living with HIV/AIDS (PLWHA). Methods: Descriptive study performed with data from the Health Information Systems of the Ministry of Health. Historical sets of indicators related to detection of HIV/AIDS cases and deaths were developed, comparing with national and state data from 2005 to 2015. Also, the cascades of care for PLWHA were elaborated for the municipality between 2013 and 2015. Results: AIDS detection rates of Uruguaiana were higher in comparison to the country and state, the same happened with the mortality and lethality indicators, which varied between 35.1 and 17.7 deaths/100,000 inhabitants and 6.5 and 2.7 deaths/100 inhabitants, respectively. The cascades of care for PLWHA showed an increase in individuals diagnosed with HIV in the period (from 1,125 to 1,527). The main gap occurred between the “diagnosed” and “connected” categories, expanding over time (78, 48 and 43.4%, respectively). There was a low proportion of individuals in the “undetectable viral load” category in the three years, ranging from 32 to 22.9%. Conclusion: Indicators of detection, mortality, and lethality due to HIV/AIDS are high in Uruguaiana, with an increase in the number of people diagnosed with HIV and decrease in their link with health services, suggesting the need for advances in strategies to attract and link PLWHA to the health care network.

“…Quanto ao alcance da meta 90-90-90 dos indivíduos em TARV e com supressão viral, nosso estudo apresentou percentuais inferiores ao proposto pela meta, alinhado com pesquisa realizadas por Rossi et al (2020) [20] e Davoglio et al (2021) [25] os quais evidenciaram resultados inferiores ao esperados de supressão viral.…”

HIV and AIDS in the state of Paraná, Brazil, 2007-2022: trends and spatiotemporal distribution

“…The economic, demographic, and social dynamics of the coastal region are influenced by the dynamism of the Port of Paranaguá, and other factors such as the location of the state's major roadways, high fluctuating population density, mobility, seasonal labor migration, and tourism are elements that can contribute to the propagation and maintenance of HIV 34,37 . These characteristics, also recognized in border regions, represent critical points facilitating multiple casual partners, unprotected sexual relations, drug concentration, and sexual exploitation 38 . This implies implementing prevention strategies tailored to the local context, taking into account the population-specific characteristics within the context of combined HIV prevention 39 .…”

“…However, with the implementation and free offer of ART by the Unified Health System (SUS) it was possible to evidence a reduction in mortality caused by the disease (Castro et al, 2020). In this sense, studies are needed to monitor the trend of infection and analyze the quality of care in each municipality (Davoglio, Gandin, & Mocellin, 2021).…”
