Hantavirus is a virus carried by some wild rodents. It is uncommon, but it can cause serious lung illness. People are mainly exposed by breathing in dust from droppings, urine or nests.
Food, dishes and shelves that rodents touched are sorted. Items that cannot be sanitized are discarded, and hard surfaces are cleaned and disinfected. Anything in sealed containers can usually be saved.
The odor comes from urine in insulation, wood and fabric, so it must be removed or treated at the source. Crews take out soaked insulation and treat surfaces. Air fresheners only cover the smell.
