According to the California Department of Health, the individual lives in South Lake Tahoe and is currently recovering at home while also receiving medical care. Officials confirmed that county health workers are closely monitoring the situation.
Authorities believe the illness came from an infected flea bite during a camping trip in the South Lake Tahoe area. An investigation is underway, and health warnings have been issued urging the public to remain alert.
South Lake Tahoe last saw a plague case in 2020. Before that, two visitors to Yosemite National Park tested positive in 2015 after being exposed there.
Many people recognize the plague as the ‘Black Death’ from history, which swept across Europe in the 14th century and tragically killed as much as half of the continent’s population.

Pneumonic plague is the most dangerous and least common form, as it spreads to the lungs and can develop from untreated versions of the illness.
Symptoms of bubonic plague typically appear within two to eight days after exposure. They include fever, chills, headaches, swollen lymph nodes, and a general sense of weakness.
“Plague is naturally present in many parts of California, including higher elevation areas of El Dorado County,” said Kyle Fliflet, acting public health director for El Dorado County.
“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.”

Because of this, pets can also accidentally bring plague-carrying fleas into homes, putting owners at risk.
In July, Arizona reported its first plague-related death since 2007. The individual had contracted pneumonic plague after coming into contact with a dead animal infected with the bacteria.
