Reviewed by Yoshinori Abe, MD

Internal Medicine

Chikungunya virus does not spread directly from person to person. It is transmitted primarily through the bite of infected mosquitoes, most commonly Aedes aegypti and Aedes albopictus species. When a mosquito bites someone infected with the virus, it can then pass it to others through subsequent bites.

If you've been bitten by mosquitoes and are experiencing symptoms like fever, joint pain, rash, or fatigue, it's important to understand what may be causing them. Taking a free, instant, online symptom check can help you identify possible conditions and guide you on the right next steps—whether that means monitoring at home or seeking medical care.

Key Points:

Transmission Method: Chikungunya virus is spread by mosquitoes, not by direct contact between people.
Mosquito Role: The virus is transmitted when a mosquito bites an infected person and then bites someone else.
