Hantavirus context · United States of America

United States of America sits in the Americas, where hantavirus infection most often takes the form of hantavirus pulmonary syndrome (HPS), the cardiopulmonary form first recognised during the 1993 Four Corners outbreak.

Across this region the principal reservoirs are Sigmodontinae rodents — most notably the deer mouse (Peromyscus maniculatus) in North America and Oligoryzomys species across the Southern Cone. Human exposure typically happens through inhalation of aerosolized droppings, urine, or saliva from these rodents — most often in rural housing, agricultural buildings, or poorly ventilated indoor spaces with recent rodent activity.
