Chikungunya is a virus spread to people by mosquito bites. Mosquitoes become infected when they feed on a person already infected with the virus. Infected mosquitoes can then spread the virus to other people through bites. Most people infected with chikungunya will develop some symptoms. The most common symptoms of infection are fever, joint pain and swelling. Others may include headache, muscle pain or rash that can last for a week or longer. These symptoms can be severe and disabling. The best way to prevent getting infected is to protect yourself and your family from mosquito bites.
