Infectious disease that can cause severe illness in individuals with pulmonary syndrome (HPS), a severe disease that affects the lungs; HPS can be life-threatening among patients who have severe respiratory symptoms. It is most commonly transmitted (spread) to humans through contact with infected rodents (e.g., urine, droppings, saliva). Rarely, infection can occur from rodent bites or scratches. Clinicians should be aware of the potential for imported cases, although the risk of broad spread to the United States is considered extremely unlikely at this time.
