the black plague
They did die. After they were infected by the fleas that were the original carriers, they got sick. They transmitted the virus inadvertantly through the food they nibbled off of in humans' pantries. Humans would eat this food and get infected with the black plague. Towards the end of their lives, as the virus progressed, the rats would go a tad loopy and bite humans, therefore directly transferring the virus to humans. The rats then died. Other creatures would feast on the rat's corpse and be infected. The cycle continued.
humans haven't even got the full capacity so the answer is no
