There are two main species of mosquitoes of the genus Aedes (Aedes aegypti and Ae. albopictus) capable of transmitting dengue and other arboviruses such as Zika, chikungunya, and yellow fever. The present study aimed to characterize data on arboviruses and their correlation with the population density of vectors, climatic and socio-environmental factors in the city of João Pessoa-PB. We selected districts in the neighbourhood that integrate two distinct strata organized and grouped according to the Survey of the Rapid Index of Ae. aegypti (LIRAa) in the municipality of João Pessoa-PB. Stratum I, composed of districts with low quality life indicators, while stratum II grouped neighborhoods with better indicators. In these strata, epidemiological data were compared with the population density of vectors, climatic and socioeconomic factors from 2015 to 2017. It was found that Stratum II presented a strong correlation between the Building Infestation Index and the climatic variables related to precipitation and relative humidity. According to epidemiological data, Stratum I presented a higher number of dengue, Zika and chikungunya notifications, with significant difference (p = 0.001) in relation to Stratum II. Results indicated thatthe Breteau and building infestation indices are considered high; these data indicate that the population presents a higher probability of risk of arbovirus outbreak, mainly in periods of greater rainfall due to the accumulation of water in artificial reservoirs.
