DENVER (KDVR) — The West Nile virus was found in a mosquito sample in Larimer County, marking the first detection in the area this season.

On Monday, Larimer County said a mosquito sample tested positive for the West Nile virus after they were found in the southeast area of Fort Collins. This comes after the county began testing mosquitoes in Larimer County during the first week of June.

“This first detection is a reminder that now is the time to make a plan to protect yourself,” said Tom Gonzales, Larimer County Public Health Director at the Larimer County Department of Health and Environment. “It only takes one tiny mosquito to have a big impact on your health. Taking even one extra step to protect yourself can significantly reduce your risk.”

The West Nile virus spreads through infected mosquito bites and causes anything from flu-like symptoms to severe illness. The county said most people don't experience symptoms, but about one in five infected people could see symptoms like fever, headaches, body aches, fatigue, vomiting, diarrhea and rash.

Meanwhile, about one in 150 infected people could see symptoms like high fever, headache, neck stiffness, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. 

So far, the county said there are no reported human cases.

How to protect yourself from the West Nile virus

The county said this detection marks the start of heightened risks to residents, especially during warmer months and peak West Nile season from July through August.

The county recommends the following practices to stay safe:

• Use an EPA-registered insect repellent
• Wear loose-fitting, long-sleeved shirts and pants when you're outside
• Avoid outdoor activities during "peak biting times," which are around dawn and dusk

The Larimer County Department of Health and Environment is working with the community to monitor and assess the risk to residents in Larimer County.
