Chikungunya is a viral disease transmitted by the bite of infected mosquitoes such as Aedes aegypti and Aedes albopictus. It can cause high fever, muscle and muscle aches, and headache. While chikungunya does not often result in death, joint pain associated with the disease may persist for months or years and may become a cause of chronic pain and disability. There is no specific treatment for this infection and no vaccine to prevent it.
