EASTERN OREGON – The Central Health District in Idaho recently confirmed two cases of West Nile Virus infection among humans in both Canyon County and Ada County. A description of the specific infections and potential symptoms (as provided by the Central Health District) is as follows:

“Idaho’s first two human West Nile virus (WNV) infections this year were identified in a female Canyon County resident who is over the age of 60 and a male Ada County resident who is also over the age of 60 on Monday, Aug. 26. The Canyon County person was hospitalized with the infection but has been discharged. So far this year, WNV activity has been detected in six Idaho counties, three of them in Southwest District Health’s and Central District Health’s regions.

WNV is spread by the bite of an infected mosquito and can lead to severe disease in some people.

Symptoms of WNV infection often include fever, headache, body aches, nausea and, sometimes, swollen lymph glands or a skin rash. Infection can result in severe illness, especially in people 50 years or older, leading to hospitalization and even death. Talk to your healthcare provider about testing for WNV to confirm your illness.”

While no confirmed human infections of West Nile Virus have occurred in Eastern Oregon so far this year, there remains a risk of infection in some areas. Canyon County Idaho does border a portion of Malheur County Oregon. Baker County has also reported several confirmed cases of West Nile Virus present in local mosquito pools this summer, with the latest such confirmation around August 16. Malheur County also confirmed it’s first case around August 2. Union County Vector Control has not confirmed any cases of West Nile Virus among local mosquitos this year so far.

Oregonians and Idahoans alike are urged to take precautions and preventative measures when dealing with mosquitoes this year. As further recommended by the Central Health District:

“Cover up exposed skin when outdoors and apply DEET or other EPA-approved insect repellent to exposed skin and clothing. Carefully follow instructions on the product label, especially for children.
Insect-proof your home by repairing or replacing damaged screens.
Reduce standing water on property. Check and drain toys, trays or pots outdoors that can hold water.
Change bird baths, static decorative ponds, and animal water tanks weekly to reduce suitable mosquito habitats.”
