[Indigenous, introduced and airport malaria in Europe]

Abstract

Mainly due to P. vivax, the autochtonous malaria - sometimes caused by P. malaria, scarcely by P. falciparum - is spread in the whole Europe until the 18th century, decreasingly during the second part of the 19th century, while the latest documented cases were noticed in Macedonia, 1974. In France malaria spontaneously disappeared in 1943 on the mainland, and after, DDT house-spraying, in Corsica, 1959-60 (in spite of a temporarily reintroduction run in 1970). Malaria is now eradicated from Europe officially since 1975. Since 1969, approximatively 60 cases of autochtonous "airborne or airport malaria" have been officially reported from various European countries : Belgium, Germany, Italy, Netherlands, United Kingdom, Spain, Swiss, and France. Most of the 23 cases run into France were due to P. falciparum and appeared during summer. All patients were living, working or both, in the vicinity of an international airport or harbour (2 cases). Few of theses cases queerly involved a second-step carriage of Anopheles. The illness is usually severe and case fatality rate is therefore high, because of the subject's absence of premunition and no history of tropical travel, and then, the infection may be unfortunately misdiagnosed. According to the International Health Regulations, disinsection of aircrafts must be systematically done and even enhanced as soon as possible. On the other hand some of new methods for the aircraft disinsection and improved international vector control must be developped.
