On Thursday, the Iowa Department of Public Health (IDPH) announced the first case of West Nile virus (WNV) infection reported in 2021, an older adult (aged 61 years to 80 years) from Montgomery County.
“Humans get infected with West Nile virus through a mosquito bite and being outside means there’s a risk for West Nile virus infection. But we have easily accessible preventive tools like insect repellent, that can help keep Iowans safe from mosquito bites, which lowers the risk of West Nile infection” said IDPH Medical Director & State Epidemiologist Dr. Caitlin Pedati.
IDPH reminds all Iowans take the following steps to reduce the risk of exposure to West Nile virus:
- Use insect repellent with DEET, Picaridin, oil of lemon eucalyptus or IR3535.
- Always read the repellent label and consult with a health care provider if you have questions when using these types of products for children.
- For example, oil of lemon eucalyptus should not be used on children under 3 years of age and DEET should not be used on children less than 2 months of age.
- If possible, avoid outdoor activities between dusk and dawn, when mosquitoes are most active.
- Wear long-sleeved shirts, pants, shoes and socks outdoors whenever possible.
- Eliminate standing water around the home because that’s where mosquitoes lay eggs. Empty water from buckets, cans, pool covers and pet water dishes. Change water in bird baths every three to four days.
In 2020, 3 Iowans were diagnosed with West Nile virus, with zero deaths.
According to the CDC, WNV is the leading cause of mosquito-borne disease in the continental United States. It is most commonly spread to people by the bite of an infected mosquito. Cases of WNV occur during mosquito season, which starts in the summer and continues through fall. There are no vaccines to prevent or medications to treat WNV in people. Fortunately, most people infected with WNV do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms. About 1 out of 150 infected people develop a serious, sometimes fatal, illness.
