Hantavirus is an uncommon but potentially life-threatening disease transmitted primarily through contact with infected rodents or their excreta, including droppings, urine, and saliva. In the United States, most hantavirus infections occur in rural or semi-rural regions where rodent species such as deer mice are prevalent. Unlike viruses that spread easily from person to person via respiratory droplets, hantavirus transmission mainly happens when people inhale dust particles contaminated with rodent waste. This mode of transmission significantly limits the virus’s ability to cause widespread outbreaks.

Factors Affecting Hantavirus Exposure in the U.S. Include:

• Density and proximity of rodent populations to human habitats
• Seasonal changes influencing rodent behavior and human outdoor activities
• Implementation of rodent control and…
