If you are traveling abroad, you
should be aware that in some countries, aircraft passenger compartments are sprayed
insecticide while passengers are on board. This is done to prevent bringing in
mosquitoes and other insects from one country to another. The World Health Organization
has found these procedures to be safe, but they may make certain health conditions
worse. These include allergies, asthma, and certain respiratory disorders.
Countries where this process
generally takes place include those in Latin America, the Caribbean, Australia, and
South Pacific regions. For more information about these procedures, contact your travel
agent or airline.
