Health Officials Warn After Man Contracts Plague in California
A man camping in South Lake Tahoe, California, has tested positive for the plague, caused by the bacterium Yersinia pestis. Health officials believe he was bitten by an infected flea during his trip. This case has prompted warnings to residents and visitors to exercise caution when outdoors in the area, particularly in regions where wild rodents are prevalent.
The unnamed individual is currently receiving treatment and is recovering at home, according to officials from El Dorado County. Kyle Fliflet, acting director of public health for the county, stated, “Plague is naturally present in many parts of California, including higher elevation areas of El Dorado County.” He emphasized the importance of taking precautions for both people and pets when walking, hiking, or camping in such environments.
Plague bacteria are primarily transmitted by fleas that have fed on infected wild rodents, including squirrels and chipmunks. Pets, such as dogs and cats, can also carry these infected fleas. Health officials advise that “plague can be prevented by avoiding contact with wild rodents and by keeping pets away from rodent burrows.”
Symptoms of the plague can manifest within two weeks of infection and may include fever, nausea, and general fatigue. Fortunately, if diagnosed early, the plague can typically be treated effectively with antibiotics.
Prior to this incident, cases of plague in humans have been rare in El Dorado County. The last reported case occurred in 2020, also likely linked to exposure in the South Lake Tahoe area. In 2015, two individuals were reported to have contracted the plague after being exposed to infected rodents or their fleas in Yosemite National Park. All these cases were treated successfully, marking the first human cases in the state since 2006.
According to the Centers for Disease Control and Prevention (CDC), the United States sees an average of seven cases of plague each year, primarily in the western states. A notable incident occurred in July 2023, when a man died in Flagstaff, Arizona, marking the first recorded death from pneumonic plague since 2007.
The historical context of the plague is significant, as the bacterium was responsible for the Black Death in the 14th century, which decimated Europe’s population, killing approximately 50 million people and wiping out around 20% of England’s population.
As health officials in El Dorado County continue to monitor the situation, they remind the public of the importance of being aware of potential risks when spending time outdoors in areas where wildlife is present.
