What is chikungunya?
Chikungunya is an illness caused by a virus that spreads through mosquito bites. The most common symptoms of chikungunya are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash.
Who is at risk?
Travelers who go to Africa, Asia, parts of Central and South America, and islands in the Indian Ocean, Western and South Pacific, and Caribbean are at risk. The mosquito that carries chikungunya virus bites primarily during the daytime, both indoors and outdoors, and often lives around buildings in urban areas.
What can travelers do to prevent chikungunya?
There is no vaccine or medicine to prevent chikungunya. The only way to prevent chikungunya is to prevent mosquito bites. Preventing bites can be difficult, but it is important, as you can get sick after just one bite. Follow these steps to reduce the chances that you will be bitten by mosquitoes during your trip.
Prevent mosquito bites:
- Wear long-sleeved shirts and long pants.
- Use EPA-registered insect repellents with one of the following active ingredients: DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone. Find an EPA-registered insect repellent that’s right for you.
- Always follow product directions and reapply as directed.
- If you are also using sunscreen, apply sunscreen first and insect repellent second.
- When using insect repellent on children
- Do not use products containing oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD) on children under 3 years old.
- Do not apply insect repellent to a child’s hands, eyes, mouth, cuts, or irritated skin.
- Adults: Spray insect repellent onto your hands and then apply to a child’s face.
- Use permethrin-treated clothing and gear (such as boots, pants, socks, and tents). You can buy pre-treated clothing and gear or treat them yourself.
- Treated clothing remains protective after multiple washings. See the product information to find out how long the protection will last.
- If treating items yourself, follow the product instructions carefully.
- Do not use permethrin directly on skin.
- Stay and sleep in screened or air-conditioned rooms.
- Use a bed net if the area where you are sleeping is exposed to the outdoors.
