Arapahoe County has identied its rst case of a person being infected with West Nile virus for the 2023 season, the county announced Aug. 3.

West Nile virus is the leading cause of mosquito-borne disease in the continental United States, according to the Centers for Disease Control and Prevention. e virus is commonly spread to people by the bite of an infected mosquito.

Most people infected with West Nile virus do not have symptoms, according to the Colorado Department of Public Health and Environment. However, some infected people can develop a serious and potentially deadly illness.

Given that there are no vaccines to prevent — or medications to treat — West Nile virus in people, health o cials are urging residents to take precautions at all outdoor locations to prevent mosquito bites.

Arapahoe County recommended the following steps to limit exposure to the virus:

Wear an insect repellent that is approved by the Environmental Protection Agency, such as one that includes the ingredient “DEET.”

Arapahoe County said these repellents are proven safe and e ective for all people ages 2 months and up, including those who are pregnant and breastfeeding. Stay indoors at dawn and dusk, as this is when mosquitoes are the most active. Avoid recreating around standing water sources such as lakes and ponds. If you are camping, use mosquito netting. Wear clothes to protect against mosquitoes, such as long-sleeved shirts and pants. Drain standing water sources including puddles, gutters, owerpots, tires, pool covers, boats and tarps. Prevent mosquitoes from getting indoors by using an air conditioner or fans rather than open windows. If you do have any windows or doors with openings, put a screen on them. If you live on a property with a septic system, take steps to prevent mosquitoes by ensuring your tank is in good repair and any vents or openings are covered or sealed.
