The Iowa Department of Health and Human Services on Friday announced that a Buena Vista County resident is infected with the first case of West Nile virus this year.
The resident is a middle age adult between the ages of 41 and 60. The case was confirmed through a test at the State Hygienic Lab.
West Nile virus in humans is caused by a mosquito bite. The risk can be lowered by applying insect repellent, avoiding outdoor activities between dusk and dawn, wearing long-sleeved shirts, pants, shoes, and socks outdoors whenever possible, and eliminating standing water around the home.
Six Iowans were diagnosed with West Nile virus last year. None of those cases resulted in deaths.
