West Nile Virus Detected in Colorado: First Human Case of 2023

The first human case of West Nile virus in 2023 has been confirmed in La Plata County, Colorado. The virus has been detected in multiple counties across the state, with increased mosquito activity due to heavy rainfall. While most infected individuals do not show symptoms, older adults and those with certain medical conditions are at higher risk. The Colorado Department of Public Health & Environment advises using insect repellents, limiting outdoor activities during peak mosquito hours, wearing protective clothing, eliminating standing water, and mosquito-proofing homes to prevent transmission.
