Chikungunya: epidemiologia e distribuição espacial dos casos de Chikungunya, no município de Palmas - TO no período de (2015-2022)

Abstract

Chikugunya is an arboviral disease transmitted by female mosquitoes of the genus Aedes ssp, characterized by fever, polyarthralgia, and polyarthritis. It is considered a public health problem in Brazil and has shown significant growth in recent years, where in the year 2022 its incidence rate was 62.% per 100,000 inhabitants in Brazil. The study aims to analyze the spatial and temporal dynamics of Chikungunya cases in the municipality of Palmas, Tocantins, in the period from 2015 to 2021. It is a descriptive quantitative ecological epidemiological study that will address the analysis of spatial correlation of Chikungunya rates with social aspects in the city of Palmas - To in the period of 7 years. It will include all the population who were diagnosed with Chikungunya in the period 2015-2022, registered in the Notificasus database. Sociodemographic, clinical and laboratory data and pre-existing comorbidities will be evaluated. Social vulnerability and social vulnerability index (IVS) data will also be collected, and in relation to climatic factors, data will be collected through the National Institute of Meteorology (INMET). Incidence rates (TI) and mortality rates (TM) will be calculated, the projection of trend and concentration of cases will be performed through Kernel analysis and Moran analysis for global spatial autocorrelation. MINITAB 19 software will be used for data manipulation and analysis to perform the temporal analysis of cases with a 7-day moving average. The trend analysis will be performed by the Prais Winsten test. With the development of this research it is expected to provide data and subsidies for the development of actions and strategies for dealing with Chikungunya in Palmas - TO.
