Japp, minns att de gjorde likadant innan vi skulle landa i Singapore (flög med Singapore Airlines). Det var ungefär 3 år sen, då SARS-epidemin härjade i Sydostasien.

As the SARS syndrome "appears to be spreading via air travel, the CDC advised travelers to postpone any non-essential travel to affected areas, which include China, Hong Kong, the Philippines, Singapore, Thailand, and Vietnam, according to WHO."26
What most travelers don't realize is that airlines routinely apply pesticides to airplanes, especially those on Asian routes. Airlines call their pesticide application "disinsection." A US Department of Transportation memo describes two methods of application: "Either spray the aircraft cabin, with an aerosolized insecticide, while passengers are on board or treat the aircraft's interior surfaces with a residual insecticide." 27
