Two more humans tested positive for the West Nile virus in Idaho, in addition to the Ada County woman who tested positive for the virus last month.
The first new case is a female in her 50s from Payette County, and the second case is a man in his 20s from Owyhee County.
West Nile virus is a potentially serious illness that is usually spread to animals and humans through the bite of an infected mosquito. It does not spread from person to person.
In August, a woman older than 65 contracted West Nile near Marianne Williams Park, on Barber Valley Drive in Boise.
Never miss a local story.
Most people infected with the illness do not show symptoms. People with symptoms may experience fever, headaches, body aches, fatigue, nausea, vomiting and sometimes swollen lymph glands or a skin rash that typically occurs two to 14 days after the bite of an infected mosquito.
“About one in 150 people infected with West Nile virus develop severe illness such as encephalitis (inflammation of the brain) or meningitis (inflammation of the linings of the brain and spinal cord),” said Jennifer Tripp, Program Manager for Southwest District Health, in a news release. “These more severe infections are marked by a rapid onset of a high fever, headache, neck stiffness, body aches, disorientation and tremors.”
In response to elevated populations of active adult mosquitoes and recent testing, aerial spraying will take place in parts of Payette County, weather permitting, between 7:30 p.m. and midnight. For more information on this spraying, please contact the Payette County Mosquito Abatement District at 208-642-6835.
Owyhee County does not have a mosquito abatement district.
