How will an increase in extreme weather events impact the incidence of dengue ?: A Systematic Review

Abstract

Dengue fever (DF) is a mosquito-borne infectious disease which occurs in over 126 nations (Li et al., 2022)
DF is caused by an RNA virus of the Flavivirus genus (Hossain et al., 2022), and is transmitted primarily via Aedes aegypti or sometimes Aedes albopictus (Li et al., 2021)
Female mosquitoes lay eggs on or next to the water surface and feed on blood by biting humans and transmit the virus when infected (Christofferson and Mores., 2016, Chan and Johansson., 2012 and there is a lag period (Kao et al., 2023)
Dengue is a particularly climate sensitive disease (Cheng et al., 2021)
Many studies have analysed climatic variables (mainly temperature, rainfall and relative humidity) and DF (Cheng et al., 2021); however, few have analysed the impacts of extreme weather events (EWEs)
This study analyses the literature on the impact of heatwaves, tropical cyclones (TCs), extreme rainfall, extreme humidity and floods on DF incidence
