The environmental factors like Rainfall, Temperature and humidity promote the spread of malaria.
Explanation:
Malaria is caused by Plasmodium and vector of this organism is mosquitoes. Mosquitoes carry them in their body as passive vectors because they don’t get infected by plasmodium.
Female anopheles mosquito is a carrier of malarial plasmodium. Stagnant water during the rainy season makes those water as a breeding pool for mosquitoes. Also, humidity and rain triggers breeding of mosquitoes. If the infected mosquitoes bite a person, he gets affected with malaria. This is most common in tropical countries during the monsoon.
