Two More Adults Die from West Nile Virus in Colorado

As of August 28, 2025, the West Nile Virus outbreak in Colorado has continued to escalate, with two more adult deaths reported in the state. Earlier this week, Montrose County Public Health confirmed the death of a man in his early 80s due to the virus, marking the first fatality in the county this year. Additionally, Larimer County officials announced that an adult in Fort Collins infected with the virus has also succumbed to the illness.

In response to the rising cases, local health authorities are urging residents to take precautions against mosquitoes. Lisa Gallegos, the Communicable Disease Coordinator for Montrose County, encouraged people to regularly use EPA-registered insect repellent, wear loose-fitting long-sleeved clothing, and avoid outdoor activities during peak biting times around dawn and dusk. Larimer County has also conducted multiple rounds of mosquito spraying in an effort to curb the infected population, with another round scheduled for August 28.

The West Nile Virus can cause a range of symptoms, from no symptoms at all to severe, potentially deadly complications. Health officials advise anyone experiencing fever, fatigue, headaches, body aches, rash, or swollen lymph nodes to seek medical attention immediately.
