BRITOS, Milena. Implication of climate change on the appearance of the risk of dengue transmission by Aedes aegypti and its adaptation to local environmental conditions. A systematic review. Rev. Soc. cient. Parag. [online]. 2022, vol.27, n.1, pp.120-137. ISSN 2617-4731.

Abstract: Climate change is global warming, a consequence of the production of greenhouse gases and produces excess heat in the lower layers of the atmosphere. These changes in the climate can lead to alterations in the life cycles of several species such as Ae. aegypti mosquitoes, considered an important disease transmission vector. The objective of this work was to carry out a brief systematic search of articles related to the possible relationship between climate change and the appearance of the risk of transmission of dengue fever by Ae. aegypti and its adaptation to local environmental conditions. For this, a systematic search was carried out in three different databases: Scopus, Google Scholar and CICCO (Springer link, Scielo, DOAJ). Three key questions were taken from which the search keywords and logical sentences were derived. A flowchart was obtained showing how the search number was reduced from 651 to 27 cientific articles. Factors such as urbanization, lack of basic services, and variations in temperature, environmental humidity, and precipitation can increase the risk of epidemics at a global level, since various insects, especially Ae. aegypti change to adapt to local environmental conditions.

Palavras-chave : climate change; epidemics; epidemiological risk; environmental variables; Aedes aegypti.
