Two cases of falciparum malaria acquired in Britain

Two cases of severe falciparum malaria contracted in the United Kingdom occurred in residents of Sussex, living 10 and 15 km from Gatwick airport. One patient was the landlord of a public house much frequented by aircrew, and the other was the wife of a worker at the airport, who travelled close to the public house on the probable date she contracted her infection. Transmission was most probably due to the bite of an infected imported tropical anopheline mosquito transported in a vehicle from the aircraft to the site of transmission during the very hot and humid weather of July 1983. Prevention of further cases depends on increased diligence in "blocks-away" destruction of insects in aircraft flying from endemic areas, but there is a need for more study of acceptable alternative ways of delivering the insecticide. This "airport malaria" is well recognised on the continent, and physicians should be aware of its existence in those who have not travelled abroad but live or work near international airports.
