The first U.S. case of the mosquito-borne virus Chikungunya has been reported in Florida.
The virus was first detected in the Carribean seven months ago and since then, more than 200 American travelers to that area have brought the virus home.
However, the case in Florida marks the first time mosquitoes in the United States are thought to have infected someone who did not travel.
Symptoms include fever and joint pain.
While it is rarely fatal, it can be debilitating.
The Centers for Disease Control and the Florida Department of Health are working to learn how this patients got the virus and whether there are any additional cases.
