A high risk of West Nile Virus is present across Iowa, with mosquito surveillance showing activity levels not seen in over two decades. The Polk County Public Health Department urges Iowans to take precautions against mosquito bites.
To protect yourself, consider the following steps:
– Use EPA-registered bug spray
– Wear long-sleeved shirts, pants, and socks when outside
– Treat clothing with permethrin
– Remove standing water around your home to limit breeding sites
Most people infected with West Nile Virus experience no symptoms. However, one in five develop a fever, headache, or body aches, while about one in 150 face serious illness impacting their nervous systems, which can be fatal.
Older adults and immunocompromised individuals are most at risk of severe disease from the virus.
