Idaho Reports First Human West Nile Virus Case of the Year in Washington County
Washington County, Idaho – In a news release from the Idaho Department of Health and Welfare, it was announced that the first human case of West Nile virus (WNV) in the state has been identified. The infected individual, who is a resident of Washington County and over the age of 50, was hospitalized but is now recovering and being discharged home.
This year, WNV activity in mosquitoes has been detected in nine counties in Idaho, with seven of them located in the south and southwest areas of the state. Additionally, mosquitoes carrying the virus have been found in neighboring Malheur County, Oregon.
West Nile virus is transmitted through mosquito bites and can cause severe illness in some individuals. Symptoms often include fever, headache, body aches, nausea, swollen lymph glands, and a skin rash. In severe cases, particularly in individuals over the age of 50, hospitalization and even death can occur.
Dr. Leslie Tengelsen, the state public health veterinarian, urges Idahoans to take proactive measures to protect themselves and their families from mosquito bites. This includes using insect repellent, wearing protective clothing, and eliminating standing water around homes and gardens where mosquitoes can breed.
Last year, three human cases of West Nile virus were reported in Idaho, with activity detected in seven counties. Although the number of cases can be difficult to predict, as not all cases seek testing, an average of 11 cases have been reported each year in the last five years.
To minimize the risk of infection, it is advised to avoid mosquitoes, especially between dusk and dawn when they are most active. Additionally, individuals should cover exposed skin, apply EPA-approved insect repellent, and repair or replace damaged window screens to insect-proof their homes. It is important to reduce standing water on properties by eliminating items that can collect water, such as outdoor toys and pots.
While West Nile virus does not usually affect domestic animals like dogs and cats, it can cause severe illness in horses and certain bird species. Although there is no vaccine available for humans, horse owners are encouraged to vaccinate their animals annually.
