outfront tonight, board certified physician for infectious disease, thank you so much for taking the time. people hear plague, we think of black death, which killed 25 million people in the middle ages. how serious of a threat is this? i think it s not unheard of to hear of a squirrel testing positive for plague in california. any time an animal tests positive for plague in an area where humans frequent, it merits serious concern. and it s very prudent for these authorities that run the campground to close those areas to the public and to advise people to take general precautions when they are in those areas and to avoid feeding squirrels, avoid their pelt pe avoid situations where they have pleas g s fleas jump from to their pets. yeah, and we hear about the rats of the bubonic plague,
