State health officials say 19 Texans have now come down with the mosquito-borne illness known as Chikungunya.
Of those, eight cases are in North Texas.
But so far none of the cases have originated in this area. All eight contracted the virus somewhere else and were diagnosed back home.
Chikungunya virus causes high fever and severe joint pain that start suddenly. It can also cause headache, muscle pain and rash. Chikungunya 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 Chikungunya and there is not a vaccine. Avoiding mosquito bites is the key to avoid Chikungunya.
