A resident of South Lake Tahoe has tested positive for the plague, allegedly after being bitten by an infected flea while camping nearby, according to El Dorado County health officials on Tuesday. The individual is currently recovering at home.
“Plague is naturally found in various regions of California, including higher elevation zones in El Dorado County,” noted Kyle Fliflet, the acting director of public health in the county. “It’s crucial for people to take precautions for themselves and their animals outdoors, particularly while walking, hiking, or camping in areas where wild rodents might be present.”
The county mentioned that human cases of the plague are very rare, but they can be quite serious. The last case in El Dorado County occurred in 2020. Prior to that, two visitors to Yosemite National Park were infected in 2015.
This year, California health officials monitoring rodent populations have identified four rodents carrying the plague bacterium in El Dorado County. In total, 41 rodents were found positive between 2021 and 2024.
How to avoid the plague
According to health experts, the plague bacteria are primarily spread through flea bites, with fleas typically picking up the germs from infected squirrels, chipmunks, or other wild rodents. Domestic pets like dogs and cats can also bring infected fleas home.
People are advised to keep their pets leashed and away from rodent burrows. It’s also recommended that both humans and pets avoid contact with sick, injured, or deceased rodents, as well as refrain from feeding them.
To further prevent flea bites, wearing long pants tucked into boots and applying insect repellent with DEET on socks and pant cuffs can be effective. Symptoms of plague may include fever, nausea, weakness, and swollen lymph nodes. If caught early, it can be treated with antibiotics.
