First human case of West Nile in Idaho

BOISE (AP) — Officials with the Idaho Department of Health and Welfare say a southern Idaho woman has tested positive for West Nile virus, becoming the first known person to come down with the mosquito-borne illness this year.

The Twin Falls woman is in her 40s and has recovered from the illness. She had traveled to Valley County shortly before she got sick, so health officials aren't sure where she contracted the illness.

Mosquitoes in Ada, Canyon and Payette counties have tested positive for the virus so far. Symptoms include fever, head and body aches, nausea, vomiting and sometimes a rash. The virus can cause severe illness in older people or those with weakened immune systems.
