First case of West Nile virus in Iowa reported for 2024

HARRISON COUNTY, Iowa – The Iowa Department of Health and Human Services (HHS) has officially registered the first case of West Nile virus in Iowa for 2024, according to an announcement Thursday evening.

The agency said the case was reported in Harrison County in a person between the ages of 61 and 80 and was confirmed after testing at the state hygiene laboratory.

In 2023, 17 Iowa residents were diagnosed with West Nile virus, one of which was fatal.

According to the HHS, the West Nile virus can be transmitted to humans primarily through mosquito bites.

For this reason, the use of mosquito repellent measures is recommended, including:

• Using an insect repellent containing DEET, picaridin, lemon eucalyptus oil, para-menthanediol, 2-undecanone or IR3535
• If possible, wear long-sleeved shirts, pants, shoes and socks outdoors
• Know where standing water can accumulate
• Eliminate standing water, as this is where mosquitoes are most likely to breed.

According to the HHS, lemon eucalyptus oil and paramenthandiol should not be used on children under three years of age and DEET should not be used on infants under two months of age.

If you also use sunscreen, apply sunscreen first and then the insect repellent.

Some people are not even aware that they are infected with the virus. Some people experience only mild symptoms, such as fever or a mild headache. However, for others, symptoms can be more severe, including disorientation and muscle weakness.

Most infected people recover on their own. However, if symptoms such as disorientation, sudden weakness or severe headaches occur, a doctor should be consulted immediately.
