West Nile virus activity in Iowa is unusually low so far this summer, a good sign for those looking to spend the last weeks of school break outdoors. According to the Iowa Department of Health and Human Services (HHS), 14 mosquito samples have tested positive for West Nile virus in Iowa. These samples were collected from surveillance sites across the state. So far in 2024, no human cases have been reported. In 2023, Iowa recorded 17 human cases, including one death. West Nile virus is primarily transmitted to humans through the bites of infected mosquitoes. Iowans are advised to use insect repellents containing DEET, Picaridin, oil of lemon eucalyptus, or other repellants to reduce the risk of bites. Iowans can also alter their behavior to avoid mosquitoes, such as avoiding outdoor activities from dusk to dawn, wearing long-sleeved clothing, and eliminating standing water around homes to reduce mosquito breeding sites.
