Imported malaria and use of malaria chemoprophylaxis by travelers--Kentucky, Maryland, and United States, 1993-1994.

Malaria surveillance has been maintained in the United States since indigenous transmission was interrupted in the late 1940s. Most reported cases in this country are acquired during international travel or occur among persons who resided in malaria-endemic countries. During 1993-1994, the number of reported cases increased in Kentucky and Maryland. This report summarizes the investigations of these cases and compares findings with national data from 1993, which indicate many travelers who acquired malaria infection failed to take appropriate chemoprophylaxis.
