Variaciones en el vector del dengue en el contexto del cambio climático. Una revisión de la literatura

Abstract

Abstract: Worldwide, dengue has increased alarmingly, being one of the main causes of death in some Asian and Latin American countries. Dengue is an arbovirus transmitted to humans by the bite of Aedes mosquitoes, and is a disease sensitive to climate change. The objective of this study was to offer an updated review of the literature on the variations in the dengue vector in the context of the climatic changes that have occurred. The PubMed, Virtual Health Library and Google Scholar search engines were used. The selected articles were observational, which documented, in recent years, an increase in dengue transmission and vector density. The climatic factors most related to these changes were temperature and precipitation. However, such climatic changes have had a varied effect, both positive and negative, on dengue transmission and vector density. It is notorious that some publications found a predominance of transmission in rural areas and outside the home.
