Symptoms
Most people infected with chikungunya virus will develop some symptoms.
Symptoms usually begin 3–7 days after being bitten by an infected mosquito.
The most common symptoms are fever and joint pain.
Other symptoms may include headache, muscle pain, joint swelling, or rash.
Chikungunya disease does not often result in death, but the symptoms can be severe and disabling.
Most patients feel better within a week. In some people, the joint pain may persist for months.
People at risk for more severe disease include newborns infected around the time of birth, older adults (≥65 years), and people with medical conditions such as high blood pressure, diabetes, or heart disease.
Once a person has been infected, he or she is likely to be protected from future infections.
