Chikungunya fever

Chikungunya (say "chick-un-GOON-ya") fever is an illness caused by a virus that is carried by mosquitoes.

You're more likely to get this illness if you travel to parts of the world where it's more common. This includes parts of Africa, Europe, and Asia, and islands in the Indian and Pacific oceans. More recently, it has also been found in the Caribbean and the Americas.

Travelers can spread this illness. They may go on a trip and get bitten by a mosquito that has the virus. Then they get sick and come home. And if they are bitten again, they can spread the virus to mosquitoes in their home areas.

The main symptoms are fever and very painful joints. The joint pain is often in the hands and feet. Symptoms usually start within a week after the bite.

Some people also have a headache, muscle pain, swollen joints, or a rash.

Your doctor will ask about your symptoms and any recent travel. The doctor may order a blood test to confirm that you have chikungunya fever.

There is no treatment for this illness. Symptoms usually go away on their own after about a week.

Treating your symptoms may help you feel better.

• Take medicine to reduce the pain and fever. Over-the-counter medicines, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve), usually help.
• Get extra rest.
• Drink plenty of fluids.

If your pain is very bad, your doctor may prescribe stronger pain medicine. A few people have joint pain that lasts for months or even years.

Antibiotics won't help, because this illness is caused by a virus, not bacteria.
