ABSTRACT
OBJECTIVE: To analyze the temporal trend and spatial distribution of mother-to-child HIV transmission in Santa Catarina between 2007 and 2017. METHODS: This was a mixed ecological study with data from the Notifiable Health Conditions Information System. Linear regression was performed for time series analysis and the mean rates in the period and mean annual percentage changes in the rates of HIV-infected pregnant women were calculated, 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 records of HIV-infected pregnant women, with a rate of 5.6 pregnant women per 1,000 live births. The mean seroconversion rate was 13.5/100,000 live births (95%CI 6.8;20.1) and it showed a falling 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 through mother-to-child transmission decreased.

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.
Objetivo: Estimar la tendencia temporal y distribución de casos de VIH por transmisión vertical en Santa Catarina, 2007-2017. Métodos: Estudio ecológico mixto con datos del Sistema de Información de Enfermedades de Declaración Obligatoria. Se utilizó regresión lineal para análisis de series de tiempo y se calcularon las tasas medias en período y los cambios porcentuales medios anuales en las tasas de mujeres embarazadas infectadas por el VIH; de niños expuestos al VIH; y seroconversión de niños expuestos al VIH/SIDA durante el embarazo, además geoprocesamiento de datos. Resultados: Había 5.554 gestantes infectadas por el VIH, con tasa de 5,6 gestantes/1.000 nacidos vivos. La tasa media de seroconversión fue 13,5/100.000 nacidos vivos (IC95% 6,8;20,1) y mostró tendencia decreciente (APC=-99,4%; IC95%-99,9;-93,1). La tasa de seroconversión fue más expresiva en los municipios pequeños. Conclusión: Hubo una estable tasa de mujeres embarazadas infectadas por el VIH, mientras que el número de niños infectados por el VIH disminuyó.
Objetivo: Analisar a tendência temporal e distribuição espacial dos casos de transmissão vertical do HIV em Santa Catarina, de 2007-2017. Métodos: Estudo ecológico misto com dados do Sistema de Informação de Agravos de Notificação. Realizou-se regressão linear para análise de série temporal e calcularam-se as taxas médias no período e variações percentuais médias anuais das taxas de gestantes infectadas pelo HIV; de crianças expostas ao HIV na gestação; e de soroconversão das crianças expostas ao HIV/aids na gestação, além do geoprocessamento dos dados. Resultados: Foram registradas 5.554 gestantes infectadas com HIV, com taxa de 5,6 gestantes/1.000 nascidos vivos. A taxa média de soroconversão foi de 13,5/100.000 nascidos vivos (IC95% 6,8;20,1) e apresentou tendência decrescente (APC=-99,4%; IC95% -99,9;-93,1). A taxa de soroconversão foi mais elevada em municípios de pequeno porte. Conclusão: A taxa de gestantes infectadas pelo HIV foi estável e houve diminuição de crianças infectadas pelo HIV por via vertical.
ABSTRACT
The western mesoregion of the state of Santa Catarina (SC), Southern Brazil, was heavily affected as a whole by the COVID-19 pandemic in early 2021. This study aimed to evaluate the dynamics of the SARS-CoV-2 virus spreading patterns in the SC state from March 2020 to April 2021 using genomic surveillance. During this period, there were 23 distinct variants, including Beta and Gamma, among which the Gamma and related lineages were predominant in the second pandemic wave within SC. A regionalization of P.1-like-II in the Western SC region was observed, concomitant to the increase in cases, mortality, and the case fatality rate (CFR) index. This is the first evidence of the regionalization of the SARS-CoV-2 transmission in SC and it highlights the importance of tracking the variants, dispersion, and impact of SARS-CoV-2 on the public health systems.
