Where does yersinia pestis hideout?

Yersinia pestis, the bacterium that causes Plague, is most commonly associated with rodents, particularly wild rodent species such as marmots, squirrels, and voles. When these animals are infected, they can develop flea infestations, which can then transmit the bacteria to humans. Thus, the primary hideout for Y. pestis is within rodent populations and in their fleas, which can carry the bacterium. Rodent control and monitoring are vital for preventing the spread of Plague.
