20-Aug-23

World Mosquito Day is a worldwide health-contingency event observed on the 20th of August every year for the past 126 years.

During this day, various local and global communities gather around to raise awareness about the increasing populations of mosquitos, the factors enhancing them, the diseases they contract, along with means to thwart them.

History of World Mosquito Day

World Mosquito Day, it was on this day that Dr Ronal Ross discovered the association between malaria and mosquito. Surgeon-Major Ronald Ross of the Indian Medical Service in 1897 reported that he had found what appeared to be malarial pigment in mosquitoes which he had observed on the blood of persons infected with crescentic parasites.

While other researchers assumed the role of mosquitoes as only transmitters and proceeded in searching and studying the cytology of potential malarial organisms in human blood, it was Ross who finally connected the two in finding the mosquito.

He began to work with these vertebrate hosts and their plasmodia when he was stationed in Rajputana, a period between his serving in Secunderabad and Kolkata.
