Recommendations for drugs to prevent malaria differ by country of travel and can be found in Chapter 2, Yellow Fever Vaccine & Malaria Prophylaxis Information, by Country. Recommended drugs for each country are listed in alphabetical order and have comparable efficacy in that country. The usual dosage for malaria prevention in adults is 500 mg once a week. The chloroquine dose in children is based on the child's weight. Children either receive about 8.3 mg per kg of body weight about 3.8 mg per pound of body weight or the adult dose, whichever is less. Malaria prevention consists of a combination of mosquito avoidance measures and chemoprophylaxis. Although very efficacious, none of the recommended interventions are 100% effective. Mosquito Avoidance Measures Because of the nocturnal feeding habits of Anopheles mosquitoes, malaria transmission occurs primarily between dusk and dawn.
