Space-Time Trend of Arboviruses in Health Regions of Bahia: Na Ecological Study During the Covid-19 Pandemic

Abstract

Objective: To analyze the temporal trend of Dengue, Zika and Chikungunya rates in the Health Regions of the State of Bahia (RSEBA) from March 2020 to June 2021.   Theoretical reference: Arboviruses are considered a group of emerging and re-emerging zoonoses that cause serious consequences for the health of the population, generating concern for health authorities. With the impacts generated by the Covid-19 pandemic, it was postponed, requiring efforts for this health emergency. Therefore, studying the spatio-temporal trend of arboviruses becomes necessary to analyze the dynamics of the number of arbovirus cases registered in the health regions of the state of Bahia.   Method: The spatial distribution of average rates by Health Region (RS) in Bahia will be investigated and trend analysis will be carried out using simple linear regression with PraisWinsten correction.   Results and discussion: The possible findings raise the hypothesis that the fluctuations in the time series evaluated are associated with the Covid-19 pandemic and the consequent underreporting of cases   Implications of the research: As there is a lack of research in the literature that evaluates the rates of arbovirus cases in time and space, considering them as health regions, it is possible to affirm that our findings can offer the scientific community and/or public health investors subsidies to direct public policies that optimize actions on the part of these agents, taking into account the health region most affected by these diseases.
