title: Chemoprophylaxis and malaria in American servicemen returning from Vietnam.
abstract: Information relating to chemoprophylaxis and malaria in 49 men who served with the United States Armed Forces in Vietnam and who developed overt malaria after departure from Vietnam indicated that: 1) compliance with intended chemoprophylactic regimens was far optimal; 2) a history of recent prophylactic ingestion of chloroquine was not a reliable indicator of infection with chloroquine-resistant Plasmodium falciparum: 3) reported ingestion of half or more of an intended terminal chemoprophylactic regimen was associated with a prolongation of the time that elapsed before initial post-departure episodes of vivax malaria; and 4) such partial compliance with intended terminal chemoprophylaxis may have been associated with a decreased incidence of second post-departure episodes of vivax malaria.
