A resident of South Lake Tahoe has tested positive for the plague, likely due to a flea bite during a recent camping trip. Health officials report that while such cases are rare, the threat level has increased, prompting discussions about the risks associated with outdoor activities in areas where the disease can reappear. The bubonic plague, which caused millions of deaths during the 14th century, still poses isolated health risks in the United States. Experts emphasize the importance of preventive measures for outdoor enthusiasts. For those camping in the Lake Tahoe region, vigilance against flea bites is essential, especially as officials advise residents to remain cautious.
