Travel & Dengue Outbreaks

How to reduce your risk while visiting areas with dengue

International travelers’ risk of dengue infection can vary dependant on transmission in the area as well as exposure to mosquitoes. You are at greater risk when an outbreak or epidemic is occurring. If your hotel or resort does not have air conditioning or windows and doors with secure, intact screens you may be at higher risk. You should take precautions like using repellent and killing any visible mosquitoes. CDC recommends repellents containing DEET, picaridin, oil of lemon eucalyptus or IR3535 as the active ingredient. Repellent can be applied to exposed skin and/or clothing. Clothing impregnated with permethrin is another option (pre-treated or you can treat yourself). Some spatial repellent/insecticide products (mosquito coils, plug-in or butane powered devices), may assist in reducing the risk of mosquito around you.
