Climate Changes and Vector-borne Diseases With an Emphasis on Parasitic Diseases: A Narrative Review

Background: The issue of climate change has currently become a critical concern for the global community as it affects the transmission and spread of a wide range of diseases. This study aims to examine the literature and scientific evidence concerning the impact of climate change on vector-borne diseases. Materials and Methods: In this review research, a comprehensive search and review of texts was conducted in various databases, including Google Scholar, PubMed, Scopus, and Web of Science. The MeSH framework was used as the search strategy for articles published from ۲۰۰۹ to ۲۰۲۲.  Results: The results showed that weather and environmental factors can have positive or negative effects on the growth rate, mortality, and reproduction of vectors of infectious diseases. Climate changes also affect the transmission of diseases based on an unknown mechanism. In addition, weather crises, such as floods and droughts impact pathogens, vectors, and hosts of diseases. Accordingly, many vector-borne diseases have a high potential for vulnerability to climate and weather conditions because of various animal vectors and hosts. Conclusion: The prevalence and incidence of vector-borne diseases are affected by climate changes, especially parasitic diseases caused by mosquitoes, which are among the diseases sensitive to climate conditions. Therefore, it is essential to understand the mechanism of the relationship between climate change and disease transmission. It is suggested to conduct studies to provide prediction models and temporal-spatial analysis of the impact of climate changes on infectious diseases and disease vectors.
