Mosquito-borne virus making its way into the U.S.
A virus that has sickened tens-of-thousands of people in the Caribbean is starting to trickle into the United States. The virus, chikungunya, is spread by mosquitoes, and is notable for causing severe joint pain.
Rhode Island health officials report two confirmed cases in their state. They involve people who had traveled to the Dominican Republic, and then returned home last month. And, in Tennessee, another patient tested positive for the virus, after visiting the Caribbean. More cases are suspected, but not yet confirmed.
The chikungunya virus causes high fevers and joint pain, but it's rarely fatal. There is no vaccine and the main treatment is pain medication.
