In Person
Plasmodium falciparum malaria, the most severe form of this disease, usually occurs in persons traveling without prophylaxis or with inadequate prophylaxis. Most cases of malaria occur in missionaries, long-term expatriates, and immigrants who have returned to the country of their origin to visit friends and family (VFR travelers). Failure to take adequate malaria prophylaxis may occur for economic reasons or due to the mistaken belief that prolonged residence in high risk areas leads to immunity. Practical prevention strategies and the self treatment of malaria are discussed.
