Which exposure history is most strongly associated with hantavirus infection?

Rodent exposure is the key idea here. Hantavirus is carried by rodents, and humans typically become infected when they inhale dust contaminated with rodent urine, droppings, or saliva. This risk is common in places with rodent infestations or during cleanup of barns, sheds, or other enclosed spaces where droppings accumulate. Exposures to sick birds, consuming undercooked pork, or travel to tropical Africa are not the usual routes for hantavirus transmission, so they don’t fit the strongest association.
