The dynamics of drug resistance in Plasmodium falciparum.
Drug resistance of Plasmodium falciparum is not a recent phenomenon, but it became a major problem when the parasite became resistant to chloroquine, the cheapest and initially the most effective antimalarial compound that could be used for treatment and suppression. In some areas this problem is compounded by resistance to the first line of alternative drugs, and rapid loss of sensitivity to the next line. The dynamics of drug resistance are regulated mainly by drug related selection pressure and intensity of malaria transmission. Mass drug administration in its various forms, and insufficient treatment are obviously the most important motors of selection.
