Plague-infected squirrel closes California campgrounds
Los Angeles County public health department officials confirmed Wednesday that a trapped ground squirrel tested positive for plague and closed four campgrounds as a precaution. "Plague is a bacterial infection that can be transmitted to humans through the bites of infected fleas, which is why we close affected campgrounds and recreational areas as a precaution while preventive measures are taken to control the flea population," said public health officer Dr. Jonathan E. Fielding.
