World Mosquito Day 2026
World Mosquito Day is observed on August 20 each year to raise awareness about the dangers of mosquito-borne diseases such as malaria, dengue, Zika, yellow fever, and chikungunya. The day commemorates the discovery made by Sir Ronald Ross in 1897, who established that female Anopheles mosquitoes transmit malaria. It serves as a reminder of the ongoing efforts to control mosquito populations, prevent disease transmission, and advance research for effective treatments and vaccines. Organizations worldwide use this day to promote mosquito control measures and educate communities on protection against mosquito bites.
