On August 3, the Iowa Public Health Department reported the state's first death from West Nile in 2018 was an 81-year-old man who lived in central Iowa. In North America, that means that mosquito season - extending from the late spring through the fall - is West Nile season.
The Health Unit is urging the public to take steps to prevent mosquito bites.
Another mosquito trap has tested positive for West Nile in Oxford County.
The Health Department wants to remind the public that the virus is present and has been around for many years. Symptoms, which include fever, nausea, headache and muscle aches, may last from a few days to a few weeks.
"The elderly and those with certain chronic medical problems, including problems with their immune systems, are more susceptible".
Cover up with light-colored clothes, long sleeves and trousers when outdoors or while in areas where mosquito activity is high.
Use effective insect repellent such as DEET or Picaridin.
They are most active at dawn and dusk and will bite humans as well as other mammals and birds.
- Residents should also take the time to eliminate mosquito breeding sites by removing any standing water from their property.
