During the very hot 1994 summer, six new cases of airport malaria have been observed in and around Roissy-Charles-de-Gaulle airport. Four patients were regular or occasional airport employees. The two other cases were inhabitants of a city at 7 km. Entomological investigations suggest that cars of airport employees served to disseminate anophelines outside the airport areas. The six cases were very severe. One patient died. Apparently, W.H.O. recommendations on aircraft disinsecting procedures have not been fully followed. There is obviously a threat for areas near the airports.
