A study recently accepted for publication, funded in part by CPO’s International Research and Applications Project (IRAP), reviews the current research on the transmission dynamics of two mosquito-borne diseases, dengue and chikungunya, in a rapidly changing climate and suggests avenues for future study. In recent years, there has been an alarming uptick in the number and geographic spread of mosquito-borne diseases. The places where mosquitoes can thrive due to the temperature and precipitation of the area are shifting and growing as global temperatures rise and precipitation becomes more variable. Past studies have investigated interactions between parts of the climate system and phenomena that occur on different timescales, which affect the environmental suitability for disease transmission. Other studies were concerned with ecological interactions and the geography of mosquito populations. Authors of the review recommend that future research look into diurnal temperature variations, the influence of the urban heat island effect, and interactions between climate-related factors and non-climate factors such as socioeconomic status. Such future studies are pivotal in protecting human health by developing early warning systems, building a better response effort, and increasing overall preparedness for outbreaks of mosquito-borne diseases.
