A South Lake Tahoe resident has tested positive for the plague, according to El Dorado County health officials. The patient, whose identity has not been released, is under medical care and recovering at home.
Authorities believe the individual may have contracted the illness from the bite of an infected flea while camping in the South Lake Tahoe area. An investigation is currently underway.
“Plague is naturally present in many parts of California, including higher elevation areas of El Dorado County,” said Kyle Fliflet, Acting Director of Public Health.
“It’s important that individuals take precautions for themselves and their pets when outdoors, especially while walking, hiking and or camping in areas where wild rodents are present.”
The plague is caused by the bacteria Yersinia pestis, most often carried by fleas that feed on infected squirrels, chipmunks, and other wild rodents. Human symptoms usually appear within two weeks of exposure and may include fever, nausea, weakness, and swollen lymph nodes. Health experts stress that the illness is treatable with antibiotics if diagnosed early.
The last confirmed case in El Dorado County occurred in 2020, also linked to the South Lake Tahoe region.
To lower the risk of exposure, officials strongly advise against feeding squirrels, touching injured or dead rodents, or allowing pets to interact with sick or dead wildlife.
While rare, plague remains present in certain parts of California, making awareness and prevention essential for those spending time outdoors in affected areas.
