Colorado warns of hantavirus risks as rodent exposure rises in warmer months

Hantavirus remains a rare but serious health concern in Colorado. The disease, first identified in the US in 1993, spreads through contact with infected rodents. State officials continue to urge caution, especially as warmer months increase exposure risks. The virus primarily transmits when people inhale particles from rodent urine, saliva, or droppings. Deer mice, widespread across Colorado, are the main carriers. Common activities like sweeping or vacuuming droppings can stir up contaminated dust, raising infection risks.

Early symptoms often mimic the flu, including fever, fatigue, and muscle aches. As the illness worsens, severe respiratory problems can develop, requiring urgent care. There is no vaccine or cure, but early treatment improves survival chances.

Health authorities stress that the public risk remains low. Still, they recommend precautions, particularly in spring and summer. Cleaning rodent-infested areas requires protective gear—gloves, masks, and careful disinfection to avoid airborne particles. While hantavirus cases in Colorado are uncommon, the disease can be deadly without prompt care. Residents are advised to handle rodent droppings safely and seek medical help if flu-like symptoms appear after exposure. Preventive steps remain the best defence against infection.
