Rain can increase the transmission of dengue in several ways. It creates breeding grounds for Aedes mosquitoes, which transmit the virus, as they lay eggs in standing water. Rain can also flush out existing mosquito larvae, leading to new breeding sites. Additionally, heavy rainfall can displace infected mosquitoes, potentially spreading dengue to new areas. To reduce dengue transmission during rainy seasons, it's essential to eliminate standing water, use mosquito nets or repellents, and wear protective clothing to prevent mosquito bites.
Dengue is a mosquito-borne viral disease transmitted by an infected Aedes mosquito. An increase in the amount of rainfall leads to an increased number of breeding sites for Aedes mosquitoes such as water-clogged and damp areas, and water getting collected in coconut shells. The increased number of mosquitoes leads to increased dengue disease transmission.

It is an indirect relationship between rain and dengue. During rainy season, water gets clogged in empty cans, sinks etc. These are excellent spots for mosquitoes to breed. This is major reason for propagation of mosquitoes, especially the aedes aegypti, which transmits Dengue fever.
