State records first case of mosquito-borne virus

SIOUX FALLS (AP) — State health officials say South Dakota has recorded its first case of a mosquito-borne virus that has been spreading in the U.S. from the Caribbean.

State epidemiologist Lon Kightlinger tells the Sioux Falls Argus Leader that the chikungunya virus has been diagnosed in someone who was visiting the island of St. Lucia in July.

Kightlinger says the victim is an adult, but would release no other details. The victim was diagnosed in South Dakota after returning from vacation.

Chikungunya virus is rarely fatal. Infected people typically suffer fever, severe joint pain and swelling, muscle aches, headaches or rash.

Patients usually recover in about a week, although some people suffer long-term joint pain. There is no vaccine and no specific treatment.
