Tiptoeing under the floor or rummaging through your cupboard, rodents are also a way for viruses to enter your home. Marco Goeijenbier of the Erasmus hospital in Rotterdam tells us many rodents can carry viruses with them. The rodents themselves however, don’t get sick from these. They carry the virus with them for their whole life.
Like every animal, rodents excrete urine, feces and saliva. Because viruses aren’t very picky, they tag along with those droppings. This means, that wherever rodents can reach, they can leave their excrements. These excrements dry in and in this process, virus-containing aerosols are created. Inhaling these aerosols is what causes an infection.
