Implication of heat islands on dengue incidence in urban areas: a systematic review
Journal Title: Journal of Public Health and Development - Year 2025, Vol 23, Issue 1
Abstract
Urban heat island is known to adversely affect microclimate in an area which includes temperature, rainfall, relative humidity and wind velocity. These climatic changes may influence the transmission of dengue and density of Aedes spp due to their effect on the life cycle of Aedes spp which is the primary vector for dengue. This review aims to analyse existing literatures on urban heat islands and its implication on dengue incidence. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) has been used as guide for the review involving resources from three databases (Scopus, Web of Sciences, ScienceDirect). 13 articles were reviewed following the systematic review process involving the articles identification, screening, eligibility and quality appraisal. Review found that urban heat islands can be described as area with high temperature, low vegetation coverage and high percentage of built-up areas which can be associated to high dengue incidences. Higher temperature in the urban areas was also found to influence dengue transmission and may contribute to the Aedes mosquito density which is the vector that transmitted dengue viruses among the population. It is suggested that more study to be conducted to determine the implication of urban heat island on dengue incidence particularly using indicator such as urban heat island intensity (UHII), daytime and nighttime temperature, population density and socioeconomic characteristics as the study variables with the study focuses on the urban cities with higher risk of dengue transmission.
