• Learn how to prevent mosquito bites.
o Use Environmental Protection Agency-approved repellents during travel to and after returning from areas with frequent or continuous dengue transmission.
o Wear loose-fitting, long-sleeved pants and shirts.
• Control mosquitos at home indoors and outdoors.
o Use air conditioning and window screens, when possible, to lower risk for mosquito bites indoors.
o Dump and drain containers that hold water to reduce mosquito egg-laying sites in your home and neighborhood.
• Seek medical care if you have a fever or have dengue symptoms and live in or traveled
to an area with dengue outbreaks.
• If you plan international travel to an area with frequent or continuous dengue
transmission, protect yourself from mosquito bites during and after your trip.
