World Mosquito Day is observed on August 20 each year to raise awareness about the diseases spread by mosquitoes. This day commemorates the discovery made by Sir Ronald Ross in 1897, which revealed that mosquitoes are responsible for transmitting malaria. The day serves as a reminder of the importance of mosquito control and prevention measures. Various organizations and health agencies use World Mosquito Day to educate the public about the risks associated with mosquito-borne diseases, such as dengue fever, Zika virus, and West Nile virus. Activities often include community events, educational campaigns, and discussions on effective strategies to reduce mosquito populations and protect public health.
