“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 Dr. Jonathan E. Fielding, the county’s public health director. “It is important for the public to know that there have only been four cases of human plague in Los Angeles County residences since 1984, none of which were fatal.”
