CBS News reports that the mosquito-borne chikungunya virus, usually found in the Caribbean, may be heading for the United States. “The virus has been reported as close to the U.S. mainland as Puerto Rico and the U.S. Virgin Islands,” though it is important to note that these cases have originated outside of the United States. The virus causes high fevers, joint pain and swelling, headaches and a rash and pain can persist even after other symptoms disappear. Experts say that we may see a rise in cases due to the upcoming mosquito season. “No treatment or cure exists for the chikungunya virus. Doctors can treat individual symptoms, but then can only wait for the illness to pass,” which usually takes about one week. Experts advice the public to apply insect repellent and to wear long sleeves and pants whenever possible.
