Urgent Health Alert: Plague Detected in South Lake Tahoe Rodents

A critical public health alert has been issued for South Lake Tahoe following the confirmation of plague (Yersinia pestis) in a rodent sample. This discovery, made during routine surveillance by local health agencies, serves as a stark reminder of the ever-present threat of zoonotic diseases and underscores the importance of community vigilance.

Plague, a serious bacterial disease primarily affecting rodents, is transmitted to humans through the bites of infected fleas.

While human cases are rare, the presence of the bacteria in the environment warrants immediate attention and proactive measures. Local health officials are working closely with state agencies to monitor the situation, enhance surveillance, and educate the public on necessary precautions.

Residents and visitors alike are urged to exercise extreme caution, particularly when venturing into natural areas.

Key preventive measures include avoiding contact with sick or dead rodents and squirrels, as well as their burrows. Pet owners should take extra steps to protect their animals by using veterinarian-approved flea control products, as pets can carry infected fleas into homes.

Furthermore, it is crucial to keep outdoor areas around homes free of potential rodent habitats, such as woodpiles and debris.

Anyone who observes an unusual number of dead rodents or squirrels should report their findings immediately to the El Dorado County Environmental Management Department, without touching the animals.

Symptoms of human plague can include sudden onset of fever, chills, headache, weakness, and painful, swollen lymph nodes (buboes).

While readily treatable with antibiotics if detected early, delayed treatment can lead to severe illness or death. Therefore, prompt medical attention is vital for anyone experiencing these symptoms, especially after potential exposure to rodents or fleas.

The El Dorado County Public Health Department reassures the community that ongoing surveillance and public outreach are top priorities.

They emphasize that while concerning, the situation is manageable with collective effort and adherence to safety guidelines. Staying informed through official channels and practicing diligent prevention remain the best defenses against this ancient, yet persistent, public health challenge.
