First Confirmed Human Case of West Nile Virus In South Central Idaho

Twin Falls, Idaho ( KMVT-TV / KTWT-TV ) - Several counties in southern Idaho have mosquitoes which have tested positive for West Nile Virus, but now the first confirmed human case of West Nile Virus in south central Idaho has been reported, according to the South Central Public Health District. This has prompted health officials to remind people to “Fight the Bite” of mosquitoes.

“The adult male, in his forties, is recovering at home and was not hospitalized. Due to the nature of his work and the fact that he travels throughout the state, it is very difficult to pinpoint exactly where he was bitten by an infected mosquito,” said Logan Hudson, SCPHD nurse. “This is a great reminder to the public that West Nile cases typically peak in mid-August or early September, just in time for students returning to school, early hunting season, and other late summer outdoor activities, so everyone should take extra precautions.”

Four out of five people infected with West Nile show no symptoms. If an infected person does show symptoms, they might experience fever, headaches, body aches, fatigue, nausea, vomiting, eye pain, and occasionally swollen lymph glands or a skin rash. Symptoms will usually show up two to 14 days after the bite of an infected mosquito. In severe infections, the central nervous system could be affected.

Public Health officials remind individuals to take charge in protecting themselves and their families from mosquito bites. Some tips are to drain any standing water on your property that may attract mosquitoes, avoid being outside at dawn or dusk, wear long sleeves and pants when outside, use a mosquito repellent with an EPA-registered active ingredient, and make sure that door and window screens are in good condition to keep mosquitoes from getting in your home.

If someone is experiencing West Nile symptoms, they should get in contact with their local health care provider. More information can also be found at or
