Padrão sazonal dos casos de malária e a relação com a variabilidade hidrológica no Estado do Amazonas, Brasil

Abstract: Introduction: Malaria is an infectious disease of high transmission in the Amazon region, but its dynamics and spatial distribution may vary depending on the interaction of environmental, socio-cultural, economic, political and health services factors. Objective: To verify the existence of malaria case patterns in consonance with the fluviometric regimes in Amazon basin. Method: Methods of descriptive and inferential statistics were used in malaria and water level data for 35 municipalities in the Amazonas Sta… Show more

“…Another limitation is the fact that the time of day spent in each locality was not accounted for, which can affect the probability for malaria infection, due to vector activity preferences. Seasonality attributed to malaria transmission dynamics may display an important influence in this study, as reported in the literature [3,31,32,34,37].…”

“…The Alto Juruá, as a whole, is highly receptivity to malaria, since most of the population lives at the forest fringes. This forest is seasonally flooded, creating favourable breeding conditions for the malaria vector [34]. Fish farming also contributes to a high abundance of vectors in both urban and peri-urban areas.…”

“…On the other hand, the municipalities of Humaitá and Carauari (with mean yearly peaks in April) and Borba and Eirunepé (meanly yearly peaks in May) showed peaks in malaria cases in the first half of the year. Wolfarth-Couto et al 30 explain that peaks in malaria cases can also occur before August in regions where the rainfall and hydrological regime are anticipated naturally, thus leading to different seasonality patterns in malaria cases.…”

“…Lagged coherences on the annual scale of variability in which malaria cases occur on average one to four months after the peak river water levels are consistent with Wolfarth-Couto e al. 30 , who state that distinct hydrological regimes are important in the variable seasonality of malaria cases by shifting the river water flooding.…”

“…E também tem ação sobre outras zonas da América do Sul e Central, sendo a sua distribuição relacionada a quantidade de salinidade na água dessas regiões. (HIWAT, 2011;Baia-da-Silva, Djane Clarys, et al;WOLFARTH-COUTO, 2020) Por mais que este tema seja de relevância para a saúde pública no mundo, muito ainda deve ser analisado e estudado, no que diz respeito às quantidades de casos notificados, variação do clima e das zonas de florestas e os impactos que isso trazem sobre os próprios ciclos dos mosquitos vetores da malária sobre os indivíduos dessas regiões.…”
