Physicians should be prepared to provide prophylactic medications for travelers to malarious areas and to treat patients with malaria. Chloroquine hydrochloride is the suppressive agent of choice for treatment of mild infections due to all species of malaria except for those due to chloroquineresistant strains of Plasmodium falciparum. For treatment of severe infections with P falciparum and for treatment of all infections due to chloroquineresistant strains of P falciparum, quinine is the suppressive agent of choice. Chloroquine is also the prophylactic agent of choice for most travelers. To prevent infection with P vivax or P ovale, primaquine must also be given. A RBC glucose-6-phosphate dehydrogenase level should be obtained before administration of primaquine. For prophylaxis of chloroquine-resistant strains of P falciparum, no completely satisfactory regimen is presently available in the United States.
