More states report cases of mosquito-borne chikungunya virus

TAMPA, Fla., (Reuters) – A painful, mosquito-borne viral illness has surfaced across the United States, carried by recent travelers to the Caribbean where the virus is raging.

Health officials in North Carolina, Nebraska and Indiana this week reported the first confirmed chikungunya cases in those states, along with Tennessee, which has suspected cases.

Chikungunya has rapidly spread in the Caribbean in recent months, sending thousands of patients to hospitals with painful joints, pounding headaches and spiking fevers.

Florida’s 25 cases account for the majority reported in the United States, according to state health officials and the U.S. Centers for Disease Control and Prevention.

The cases in the continental United States have not been transmitted by local mosquitoes, which would raise the threat.

“It will be more difficult for the virus to establish itself here,” said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University Medical Center in Nashville, Tennessee.

Along with new reports, the CDC is monitoring chikungunya in Arkansas, California, Connecticut, Maryland, Minnesota, Nevada, New York, Virginia, Puerto Rico and the U.S. Virgin Islands.

Symptoms surface within three to seven days after a bite from an infected mosquito and typically dissipate within a week. There is no vaccine, and the virus is not deadly. Medications can help treat high fevers.
