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. Plaquenil drug test Chloroquine crystal structure High-grade drug resistance of P. vivax has been documented from the Island of Papua both Indonesian and Papua New Guinea and across the Indonesia archipelago, Thailand, Myanmar, Horn of Africa, and Brazil. 96,101 The mechanism of resistance and genetic basis of chloroquine resistance in P. vivax appears to be different from that underlying resistance to P. falciparum. 102 Polymorphism at codon 76, which causes chloroquine resistance. Results Chloroquine was the most common anti-malarial used according to surveys from 14 of 21 countries analysed, predominantly in West Africa. Chloroquine phosphate or hydroxychloroquine sulfate Plaquenil can be used for prevention of malaria only in destinations where chloroquine resistance is not present see Chapter 2, Yellow Fever Vaccine & Malaria Prophylaxis Information, by Country. 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.

The global database on antimalarial drug efficacy and resistance was initiated in 2000 to centralize data and facilitate reporting on the status of antimalarial drug efficacy in malaria endemic countries. Secondary patterns of dispersal from these surrounding areas contributed to the wider dissemination of chloroquine resistance throughout South and Southeast Asia. Countries where resistance to artemisinins or to ACT partner drugs is reported need to intensify malaria control in order to reduce the burden of the disease, and delay or prevent the spread of resistance. Prevention and containment activities need to build on, expand and accelerate ongoing national efforts to control and eliminate malaria.
