Sir Ronald Ross

World Mosquito Day is observed every year on August 20 to commemorate Sir Ronald Ross's discovery in 1897 that Anopheles mosquitoes transmit the malaria parasite to humans.

Back in 1897, nobody knew that mosquitoes could transmit diseases but it was British doctor Sir Ronald Ross who discovered on 20 August, 1897 that malaria is transmitted between humans. It was this discovery that led to the observance of 20 August as World Mosquito Day.
