Travel Medicine. The first three papers in this issue deal with a subject not previously addressed as a specific entity in the Journal. German investigators report on a study involving two regimens of halofantrine and 74 cases of acute falciparum malaria acquired in areas of Africa known to have drug-resistant parasites (see page 1). Treatments with drug administration on two days seven days apart was found to be more efficacious than with a single day treatment. This paper emphasizes the problems faced by clinicians dealing with the management of acute malaria in non-immunes who have a history of travel in areas endemic for drug-resistant malaria. Starting on page 6 is an interesting paper from Spain concerned with the diagnosis of three species of schistosomes from a cluster of patients who appeared in a traveller's clinic in Barcelona. All had visited the Dogon country in Mali and had been swimming in one or more rivers and streams.
