Arboviral diseases are generally spread through arthropods like mosquitoes, ticks, flies and bugs. These vectors and vector-borne diseases are abundant in tropical and subtropical countries. Tropical climate plays an important role in the distribution and abundance of these diseases by influencing the vector density, intensity, and temporal pattern of the vector activity. Along with these, a complex set of demographic, environmental, and social drivers such as increased global travel and trade, intensification of agriculture, climate change, rapid deforestation, unplanned urbanization, poor socioeconomic status, lack of personal hygiene and protection are the list of important contributing factors for the transmission of arboviral diseases in India.
