Malaria can never be eradicated
21 September 2012
Malaria can never be eradicated for the following reasons:
1. Mosquito is smart as resistance grows among them towards insecticides.
2. Plasmodium parasites develops drug resistance.
3.Even if vaccine is developed and human beings are protected, extra human reservoir will continue to harbour and transmit parasites. The zoonotic species P. knowlesi, prevalent in Southeast Asia, causes malaria in macaques but can also cause severe infections in humans.
4. Last but not the least, there are natural habitats of larvae in tropical areas e.g.Rain forests, in urban areas in construction sites etc. and water tables of irrigated lands in rural areas.
