Plague case in South Lake Tahoe prompts public health warning

SOUTH LAKE TAHOE, California KOLO reports that a resident has tested positive for the plague. El Dorado County health officials say the patient is under medical care and recovering at home, and investigators believe a flea bite during camping in the South Lake Tahoe area may be the source. The bacteria Yersinia pestis is typically transmitted by fleas that feed on infected wildlife such as squirrels and chipmunks.

Symptoms usually appear within two weeks of exposure and can include fever, nausea, weakness, and swollen lymph nodes. The disease is treatable with antibiotics if caught early. Prior to this case, the most recent local case came in 2020, in the South Lake Tahoe area. Health officials advise never feeding squirrels, avoiding contact with injured or dead rodents, and keeping pets away from sick wildlife.

Public health officials must balance reassurance with vigilance. This case shows that even rare diseases can surface in outdoor communities, underscoring the need for clear, practical guidance rather than alarm. The focus on outdoor etiquette and pet safety reflects a broader shift toward everyday prevention in vector-borne risks.

Local leaders may need ongoing outreach and consistent messaging across agencies to prevent misinformation and to protect both campers and residents. While the danger to the general public remains low with proper precautions, the incident highlights how tourism dependent areas must stay prepared for health threats that travel with nature.
