Officials in El Dorado County are looking into a recent case after a resident of South Lake Tahoe fell ill. The patient is receiving treatment at home and is on the road to recovery. Authorities suspect the illness may have been transmitted through a flea bite during a camping trip in the surrounding area.
An investigation is ongoing to determine the full circumstances and, although the news might raise alarms, there’s no need to panic. As strange as it may sound, the plague is present in many areas of the state and is considered endemic. This is explained in El Dorado’s press release.
How can a person contract the plague?
The U.S. Forest Service explains that bubonic plague naturally occurs in the Sierra Nevada, including the Lake Tahoe Basin and higher elevation areas of El Dorado County. The Plague is caused by the bacterium Yersinia pestis and is usually spread through the bites of fleas that have fed on infected squirrels, chipmunks, or other wild rodents. Humans can contract the disease if bitten by any of these animals that carry the bacteria.
However, though human cases of the plague can be severe, they’re also very uncommon. Before the current case, the last reported human infection in El Dorado County occurred in 2020, likely linked to exposure in the South Lake Tahoe area. In 2015, two people contracted plague after coming into contact with infected rodents or their fleas in Yosemite National Park.
What are the plague symptoms?
Symptoms of plague can develop quickly and often include fever, chills, muscle aches, weakness, and swollen, tender lymph nodes. The disease is highly treatable when caught early, so it’s important to inform your doctor about any recent travel or activities that could have put you at risk. Providing this information can help ensure a timely and accurate diagnosis.
How to avoid contracting the plague?
The U.S. Forest Service recommends taking precautions to reduce the risk of plague when visiting areas where it has been detected. Being mindful of wildlife and practicing safe habits can help protect both you and your pets.
- Steer clear of wild rodents and avoid handling sick or dead animals.
- Notify park rangers or local health authorities if you encounter unusual wildlife activity.
- Avoid camping or resting near rodent burrows, and pay attention to posted warning signs.
- Never feed rodents at campgrounds or picnic areas, and keep food and trash securely stored.
- Wear long pants tucked into boots and use insect repellent on socks and pant cuffs to minimize flea exposure.
- If possible, leave pets at home; if not, keep them leashed or confined, prevent them from interacting with rodents, and use flea prevention products.
