West Nile virus claims its first life in Colorado of the 2025 season, prompting health authorities to advise on easy, efficient precautions for individuals spending time outdoors.
West Nile Virus Poses Threat in Colorado: CDPHE Issues Prevention Guidelines
Colorado is currently facing a rise in West Nile virus cases, with nine human cases confirmed in eight different counties this year. The Colorado Department of Public Health and Environment (CDPHE) has responded by issuing guidelines for prevention, urging residents to take precautions when spending time outdoors.
According to Dr. Ned Calonge, Chief Medical Officer at CDPHE, the West Nile virus can result in neurological disease, and it's essential for individuals to prioritize personal protection. Symptoms of the virus can include high fever, headache, stiff neck, disorientation, tremors, and coma.
The current prevention guidelines in Colorado emphasize four main strategies:
- Use insect repellents: Repellents containing EPA-registered ingredients such as DEET, picaridin, IR3535, oil of lemon eucalyptus, or para-menthane-diol should be used, following label instructions.
- Limit outdoor activities at dawn and dusk: These are the times when mosquitoes that carry West Nile virus are most active.
- Wear protective clothing: Long sleeves, long pants, and socks are recommended, along with applying repellent to clothing when in areas with mosquito activity. Clothing treated with Insect Shield technology can provide additional protection.
- Reduce mosquito breeding sites: Standing water should be removed weekly from yards, gutters, and containers. Treat water that cannot be drained with Bti larvicide, and ensure homes are equipped with properly functioning window and door screens to keep mosquitoes out.
These recommendations are strongly endorsed by state and local health departments, including the CDPHE and Larimer County Health officials, given the high mosquito infection rates and past human cases.
Larimer County, in particular, has reported a very high vector index, indicating an elevated risk. Older adults and people with certain medical conditions should be especially cautious, as they are more vulnerable to severe West Nile disease.
Weekly updates on West Nile virus activity and guidance can be found on official Colorado public health websites to stay informed throughout the mosquito season. The best hiking shirts and pants can provide additional protection and comfort during outdoor activities.
Unfortunately, the virus has been found in mosquitoes in eight of the 16 counties where testing has taken place this season, and the Colorado Department of Public Health and Environment has announced the first death from West Nile virus in the state this year.
The best practices for reducing West Nile virus risk during the 2025 season are often summarized as the “Four D’s” (Dress, Defend, Drain, Dusk/dawn avoidance). By adhering to these guidelines, residents can help protect themselves and their communities from the dangers of West Nile virus.
