(CHIKV) is transmitted to people by mosquitoes. The virus causes high fever and severe joint pain that start suddenly. It can also cause headache, muscle pain and rash.CHIKV 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 CHIKV and there is not a vaccine to prevent CHIKV. Avoiding mosquito bites is the key to avoid CHIKV.
