Why is malaria far more common in regions with stagnant water bodies (puddles, water tanks, open drains)?
AStagnant water provides breeding sites for the female Anopheles mosquito, which is the carrier of the malarial parasite
BPlasmodium grows directly in stagnant water
CStagnant water dilutes antibiotics in the soil
DStagnant water carries the bacterium that causes malaria
Answer & Solution
Correct answer: A. Stagnant water provides breeding sites for the female Anopheles mosquito, which is the carrier of the malarial parasite
Malaria is caused by a Plasmodium parasite, but the parasite is transmitted to humans by female Anopheles mosquitoes. These mosquitoes lay their eggs in still water. So controlling stagnant water (covering tanks, draining puddles) — together with mosquito nets and repellents — is the most effective community-level prevention.
