Malaria is a disease caused by an infection with plasmodium parasite, which is only transmitted by the female Anopheles mosquitoes.
The parasites are spread through the bite of an infected female anopheles mosquito. These female mosquitoes need human blood to provide nutrients for their eggs which they lay in small water bodies like puddles.
The symptoms of malaria usually appear in a week. The early symptoms that could be seen are fever, headache and vomiting. Other symptoms include muscle pain and cough. According to WHO, if malaria is not treated within 24 hours, it could progress to a more severe illness which may lead to death.
