Dengue is one of the most significant mosquito-borne viral diseases affecting human populations worldwide and represents a major public health concern in tropical and subtropical countries, including India. The principal vector responsible for transmission of dengue virus is Aedes aegypti, a highly adaptive mosquito species commonly found in urban and peri-urban environments. Rapid urbanization, population growth, climate variability, poor sanitation, and increased human mobility have contributed substantially to the expansion of mosquito populations and increased dengue incidence in India. Aedes aegypti possesses several biological and behavioral characteristics including anthropophilic feeding habits, daytime biting activity, and adaptation to artificial water containers, which facilitate efficient disease transmission. The increasing burden of dengue cases in India has generated major challenges for healthcare systems and disease control programs. The present review summarizes available information regarding the biology and pathogenic significance of Aedes aegypti, mechanisms of dengue transmission, epidemiological trends of dengue in India, and major environmental factors associated with disease spread. The review further discusses current prevention strategies and future perspectives for effective vector management and disease control.
