    Information in these tables is updated regularly.4. Several medications are available for chemoprophylaxis. When deciding which drug to use, consider specific itinerary, length of trip, cost of drug, previous adverse reactions to antimalarials, drug allergies, and current medical history.

    Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. Chloroquine phosphate or hydroxychloroquine sulfate can be used for prevention of malaria only in destinations where chloroquine resistance is not present see Maps 3-9 and 3-10 and the Yellow Fever & Malaria Information, by Country section later in this chapter. Prophylaxis should begin 1–2 weeks before travel to malarious areas.

    This risk estimate is based largely on cases occurring in US military personnel who travel for extended periods of time with unique itineraries that likely do not reflect the risk for the average US traveler.6. All travelers should seek medical attention in the event of fever during or after return from travel to areas with malaria.5.

    Chloroquine is the drug of choice for treating most patients with malaria caused by P. vivax, P. ovale, P. malariae and chloroquine-sensitive strains of P. falciparum. However, due to the development of resistance, chloroquine is ineffective against most strains of P. falciparum in South America, Africa and Asia. Chloroquine resistant or resistance unknown Atovoquone-proguanil. Artemether-lumefantrine. Quinine sulfate plus doxycycline, tetracycline, or clindamycin Mefloquine. All areas should be considered chloroquine-resistant unless specifically noted as chlorquine-sensitive below. See CDC Yellow Book for country-specific details Plasmodium falciparum malaria in Haiti is considered chloroquine susceptible, although resistance transporter alleles associated with chloroquine resistance were recently detected. Among 49 patients with falciparum malaria, we found neither parasites carrying haplotypes associated with chloroquine resistance nor instances of chloroquine treatment failure.
