The development of chloroquine as an antimalarial drug and the subsequent evolution of drug-resistant Plasmodium strains had major impacts on global public health in the 20th century. In P. falciparum the cause of the most lethal human malaria, chloroquine resistance is linked to multiple mutations in PfCRT, a protein that likely functions as a transporter in the parasite’s. In Southeast Asia, however, some malaria parasites have developed resistance to artemisinin-based drugs. Although artemisinin usually kills all malaria parasites, the use of a combination of drugs – as opposed to one – helps ensure that any parasites that remain will be killed by the other drug before the resistant parasites can spread.
