Hantavirus context · Costa Rica

Costa Rica sits in the Americas, where hantavirus infection most often takes the form of Andes virus disease, the only hantavirus with documented person-to-person transmission, alongside Sin Nombre and related lineages.

Across this region the principal reservoirs are long-tailed pygmy rice rats and deer mice that thrive in rural housing, woodpiles, and agricultural buildings. 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.

How Costa Rica is tracked
