Begin 1-2 days before travel, daily during travel, and for 7 days after leaving. Factors that affect local malaria transmission patterns can change rapidly and from year to year, such as local weather conditions, mosquito vector density, and prevalence of infection.

Chloroquine is an inexpensive, globally available drug that has been in widespread human use since 1945 against malaria, autoimmune and various other conditions. Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of Plasmodium falciparum not being cured by administration of chloroquine being reported in the 1950s. Chloroquine is an aminoquinoline used for the prevention and therapy of malaria. It is also effective in extraintestinal amebiasis and as an antiinflammatory agent for therapy of rheumatoid arthritis and lupus erythematosus. Chloroquine is not associated with serum enzyme elevations and is an extremely rare cause of clinically apparent acute liver injury. 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 phosphate or hydroxychloroquine sulfate can be used for prevention of malaria only in destinations where chloroquine resistance is not present see Maps 3-09 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. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat.
