Accordingly, WHO noted that DDT should remain a tool for controlling malaria . DDT is the most affordable and most effective pesticide for controlling malaria-carrying mosquitoes. Since malaria is largely a disease among impoverished nations, affordability greatly impacts their ability to protect themselves. Limited use of DDT for public health has continued to be effective in areas where it is used inside homes and because it often causes mosquitoes to avoid the homes altogether - avoiding the exposure that promotes resistence. Similarly, increased use of pesticides becomes a greater need as the malaria parasite itself develops resistance to medicine.
Physicians use drug therapy to cure malaria.
However, as there are a limited number of effective drugs available, certain strains of Plasmodium are becoming increasingly resistant to those drugs. Thus, drug resistance is a growing problem. Furthermore, even in areas where anti-malarial drugs are still effective, treating a case of the disease can consume over a quarter of a very poor family's income. The drugs used to treat malaria include quinine, pyrimethamine, sulfadiazine, chloroquine phosphate and chloroquine sulfate, mefloquine, and tetracycline. Some malaria-causing parasites have become resistant to these drugs.
