Montrose County confirms West Nile’s first positive case

Montrose County, Colo. (KJCT) – Montrose County Public Health has confirmed its first case of West Nile Virus in a 70-year-old man. West Nile virus is most commonly spread among humans through the bite of an infected mosquito. In 2023, Montrose County reported two cases of West Nile virus.

“Now is the time to stay vigilant and prepared,” said Montrose County Public Health Director Jim Austin. “Despite cooler evening temperatures, mosquitoes are still a problem until temperatures consistently drop. Simple steps such as wearing effective insect repellent, wearing protective clothing or long-sleeved clothing, mosquito-proofing your home, and possibly staying indoors when mosquitoes are most active are critical to preventing West Nile virus help prevent.

Montrose County says most people infected with West Nile virus have no symptoms. About 20% of infected people will have flu-like symptoms, and less than 1% will develop a serious, potentially fatal illness. People over age 60 and those with certain medical conditions are at greater risk for serious illness. Consult a healthcare provider if you develop a severe headache or confusion.

Below are the precautions you should take when outdoors and in areas where mosquitoes are active.

To protect yourself:

• Use insect repellent when you go outside. Repellents containing DEET, picaridin, IR3535 and some oil of lemon eucalyptus, and para-menthane-diol products provide the best protection. Follow label instructions.
• Limit outdoor activities at dusk and dawn, when mosquitoes that carry West Nile virus are most active.
• Wear protective clothing (long pants, long-sleeved shirts and socks) in areas where mosquitoes are active. Spray clothing with insect repellent for extra protection.

To mosquito-proof your home:

• Free mosquito dunks are available, while supplies last, at the Montrose County Public Health Office (1845 South Townsend Ave., Montrose or 851 Main Street, Nucla).
• Drain the standing water in your home at least once a week. Empty water from tires, cans, flower pots, clogged gutters, rain barrels, birdbaths, toys and puddles.
• Install or repair insect screens on windows and doors.
• Replace outdoor lighting with yellow ‘insect lamps’. These attract fewer mosquitoes. These do not repel mosquitoes, just limit the quantity.
