At what altitude would you get malaria?

You wouldn't get malaria at any altitude. Malaria is a disease caused by a parasite that is transmitted through the bites of infected female Anopheles mosquitoes. Mosquitoes are unable to fly at high altitudes, so malaria is not found in areas that are above a certain elevation. The exact elevation at which malaria transmission stops varies depending on the species of mosquito and the local climate, but it is generally considered to be around 2,500 meters (8,200 feet) above sea level.
