Aedes aegypti, infectious disease, global health, climate change, South America


Tropical infectious diseases such as dengue, chikungunya, and Zika affect millions of people annually in all regions of the world. The disease burden propagated by these arboviruses has rapidly increased in recent decades due to the range expansion of their shared vector, the Aedes aegypti mosquito. The IPCC has predicted a global increase in temperatures of 1.4-5.8°C over the next century; understanding how that will affect the vector capacity of the Aedes aegypti is essential for public health planning. This paper examined findings from a systematic map of the current state of research on this increasingly important influence on infectious disease in South America. The objectives were to: (1) assess the geographical regions represented, and (2) identify potential gaps in the existing literature. We searched the PubMed database for studies published between January 1, 1980, and March 6, 2020, that evaluated the relationship between temperature and Aedes aegypti populations. Out of 83 articles included in the analysis, only 10 focused on South America. In addition, there was inequal representation in the South American countries studied in the captured literature.
