Plague in California: What You Need to Know

South Lake Tahoe, Calif., USAWed Aug 20 2025

Plague, a disease that might sound like something from history books, has made a recent appearance in California. A person in South Lake Tahoe has tested positive for this bacterial infection, likely after a flea bite during a camping trip. This isn't an isolated case either; just last month, someone in Arizona died from the plague.

What is the Plague?

It's caused by bacteria that usually infect rodents and their fleas. Humans can catch it through flea bites or by handling infected animals. Symptoms like fever, nausea, and swollen lymph nodes can show up within two weeks. The good news is, it can be treated with antibiotics if caught early.

Precautions to Take

Health officials remind us that plague is naturally found in many parts of California, especially in higher elevations. So, if you're out hiking or camping, it's important to take precautions:

  • Protect yourself and your pets from flea bites
  • Be cautious around wild rodents

Risk and Treatment

While the risk to the public is low, it's not zero. Since 2000, at least 15 people have died from plague in the U.S. So, it's crucial to stay informed and take necessary precautions. Remember, plague is a serious disease, but with quick treatment, it can be cured.
