Avoid the Sting of Mosquito-Born Illnesses

To protect yourself from mosquito-borne illnesses such as Zika virus disease and West Nile virus infection, use insect repellent that contains one of these active ingredients: DEET, picaridin (KBR 3023), oil of lemon eucalyptus (OLE—only for people older than 3 years old), para-menthane-diol (PMD), 2-undecanone, and IR3535. Do not use insect repellent on babies younger than 2 months of age. Only apply insect repellent to surfaces that are directly exposed to air—such as exposed skin and the surface of your clothing—Do not apply insect repellent underneath clothing. If you are planning to travel internationally, talk with a health care provider familiar with travel medicine 4–6 weeks before your trip. Ask about the risks of mosquito-borne illness and how to stay safe.
