U.S. health officials issue travel advisory for St. Martin

U.S. health officials issued an advisory on Wednesday about travel to the Caribbean island of St. Martin due to concerns about a mosquito-borne virus. The Centers for Disease Control and Prevention, or CDC, said in a statement it was tracking reports of the chikungunya virus, which has surfaced among some residents of the French side of St. Martin. An infection from the virus is rarely fatal, the CDC said. The CDC said it was the first time the virus, which is transmitted by the same mosquitoes that spread the dengue virus, has been reported among non-travelers in the Western Hemisphere.
