Chikungunya Virus is carried by infected mosquitoes. It causes high grade fever and severe joint pain that starts suddenly. It can also cause headache, muscle pain and rash. Chikungunya(CHIK) does not often result in death, but the symptoms can be disabling, and some people may get severe complications. There is no specific medication available to treat CHIK. There is no vaccine to prevent CHIK. Avoiding mosquito bites is the key to avoid chikungunya fever (CHIK).


Why should I be concerned about CHIK?

  • CHIK can be extremely painful and prevent those infected from performing regular daily tasks.
  • A recent outbreak in Italy revealed the chance for a similar event in the US.

How is CHIK spread?

The virus is spread by bites from infected Aedes mosquitoes. If a person is infected and bitten by a mosquito, that mosquito may later spread the virus by biting another person.


What are the Symptoms?

  • Sudden onset of high grade fever (102F or 40C)
  • Severe joint pain mainly in the arms and legs
  • Muscle pain
  • Headache
  • Back pain
  • Rash (50% of cases may develop rashes)


Symptoms appear on average 3 to 7 days after being bitten by an infected mosquito.

Most patients feel better after a few days or weeks. Some people may develop longer-term joint pain.

Complications are rare, but more common in:

  1. Infants (<1 year)
  2. Elderly (>65 years)
  3. People with other chronic conditions such as: diabetes, hypertension, etc.

*** Extra caution should be taken by people in these groups to avoid mosquito bites***


How is CHIKV treated?

There are no specific medicines for this virus. However, using medicines (other than aspirin) to lower your fever and joint pain may help. Consult a health care provider.


How can I avoid becoming infected?
AVOID MOSQUITO BITES! The following will help to reduce your chances of being bitten:

  • Wear long-sleeved shirts and long pants.
  • Use mosquito repellent on exposed skin including: DEET, picaridin, IR3535 and oil of lemon eucalyptus.
  • Ensure window/door screens are intact.
  • Use A/C when available to make households less hospitable to mosquitoes.
  • Wear permethrin-treated clothing to repel and kill mosquitoes.


How can I protect my community?

Aedes mosquitoes live in a wide range of habitats across the US. Standing water is needed for mosquito eggs to develop into adults. Preventing standing water prevents Aedes mosquitoes. Standing water can collect in tires, flower pots, cans, wading pools, drain pipes and any other open containers.

Cooperate with your area’s mosquito control program, if spraying occurs.


What should I do if I have symptoms?

  • Record your symptoms and see a doctor.
  • Protect yourself against further mosquito bites.
  • If you are sick with CHIKV, avoiding bites will help to protect others from getting sick.
