Poor parts of Africa, Asia and Oceania are the ones who suffer and getting perpetually killed by this disease, not just malaria, even dengue, yellow fever, etc which have may have cause by mosquito. Why it keeps happening is that because they don't have really help from the Government about proper health care and education on how and what to do to avoid this. People, specially on poor status, mostly rely on their homemade or even herbal treatment that we knew will not help them at all. Malaria is a curable disease.
