Yakima, WA – The Yakima Health District reports Washington State’s first detection of West Nile virus in a mosquito sample this year.
The district cited a report from the Washington State Department of Health Public Health Laboratories that a positive sample was collected from Hisey Park in Granger.
Last year, 10 mosquito samples in Yakima County tested positive for the virus. The last reported human case in the county was in 2021.
While no human, bird, horse, or other animal cases have been reported in Washington this year, officials stress the need for preventive measures.
“Now that West Nile virus has been detected in local mosquitoes, it’s important that everyone take steps to protect themselves from mosquito bites. Wearing insect repellent, covering exposed skin, and eliminating standing water around your home are simple but effective ways to reduce the risk of infection.” said Melissa Sixberry, Director of Disease Control, Yakima Health District.
Most infected people do not show symptoms, but some may experience fever, headache and body aches. Severe cases can lead to encephalitis or meningitis, especially in individuals over 60 or with certain health conditions.
There is no vaccine for West Nile virus in humans. However, horse owners can consult veterinarians about available vaccines to protect their animals.
