The WHO International Health Regulations give guidance on prevention of<unk> . Mosquito control programmes also recommend procedures for aircraft coming from endemic areas and for the receiving<unk> s, including the surrounding of area. Routine aircraft disinsection of aircraft has been shown to reduce mosquitoes on aircraft. Insecticide can also be sprayed on the ground. However, these procedures are not totally efficient and they vary from country to country. Most mosquitos on aircraft do not carry malaria. The few that do are relatively inefficient invaders. In addition, further natural protection is offered by constraints of the hosting country's climate. A list of<unk> s at risk has been proposed. International sanitary regulations require the area of<unk> s and the perimeter of around the<unk>  to be made free of Aedes aegypti and Anopheles mosquitos. However, the application of disinsection varies from country to country.
