This news has raised alarms among residents, visitors, and public health officials alike. Understanding the situation, the risks involved, and the precautions to take is essential for staying safe and informed.
Understanding the Plague in South Lake Tahoe
The plague is a serious infectious disease caused by the bacterium Yersinia pestis. Historically infamous for causing the Black Death in the Middle Ages, plague today is treatable with antibiotics if diagnosed early. However, it still poses a risk in certain regions of the United States, including parts of California like South Lake Tahoe.

-
Transmission: Plague is primarily transmitted to humans through the bite of infected fleas that live on rodents such as squirrels, chipmunks, and rabbits.
-
Symptoms: Early symptoms include sudden fever, chills, headache, fatigue, and swollen lymph nodes.
