A Wake-Up Call from South Lake Tahoe: The Plague Is Still Here
A recent plague case in South Lake Tahoe is a reminder that this ancient disease isn’t just in the history books. Here's what you need to know about its modern reality, from understanding the risks to managing your anxiety.
The word "plague" often conjures images of the Middle Ages—a terrifying historical echo of a disease that decimated populations and reshaped civilizations. It feels like something confined to history books, a morbid curiosity rather than a modern health concern. That's why recent news from South Lake Tahoe feels so jarring: a resident has tested positive for the plague.
This isn't a headline designed to spark panic, but rather to ground us in a crucial reality. While extremely rare, the plague is not extinct. It's a reminder that some of the oldest diseases still exist in our world, coexisting with modern medicine and technology. For those of us living in an age of heightened health awareness, understanding the facts about the plague in 2025 is a powerful exercise. It's about being informed and mindful, not fearful. By learning about its nature and how to prevent it, we can shift from a mindset of catastrophic worry to one of empowered awareness.
What Is the Plague?
The plague is an infectious disease caused by the bacterium Yersinia pestis. Its most infamous manifestation was the Black Death in the 14th century, which wiped out an estimated 75 to 200 million people in Eurasia and North Africa. That devastating pandemic was largely spread by fleas on rats, a primary vector for the disease.
Today, the science remains the same: the bacterium is most commonly carried by fleas that live on wild rodents like squirrels, chipmunks, and prairie dogs. When an infected flea bites a human or another animal, it can transmit the disease. There are three main forms of plague, each with distinct symptoms:
Bubonic plague is the most common form and is characterized by the sudden onset of fever, headache, chills, and painful, swollen lymph nodes called buboes.
Septicemic plague occurs when the bacteria multiply in the bloodstream. It can cause fever, chills, abdominal pain, shock, and bleeding under the skin.
Pneumonic plague is the rarest but most severe form. It infects the lungs, causing symptoms like shortness of breath, chest pain, and a cough that may produce bloody or watery mucus. This form is particularly dangerous as it can be transmitted from person to person through respiratory droplets.
The critical difference between now and the 14th century is that modern plague is treatable with common antibiotics when diagnosed and treated early. This fact fundamentally changes the nature of the threat.
The South Lake Tahoe Case
The South Lake Tahoe resident's case marks the first human plague infection reported in El Dorado County since 2020. Officials believe the individual contracted the disease while camping in the area, likely from an infected flea bite. Fortunately, the patient is currently recovering at home under medical care. This situation, while concerning, is not an isolated incident in the region's broader ecological context.
The California Department of Public Health routinely monitors rodent populations for Yersinia pestis activity. Surveillance in El Dorado County between 2021 and 2024 revealed that 41 rodents—primarily ground squirrels and chipmunks—had evidence of exposure to the plague bacterium. This year alone, four more rodents have tested positive in the Tahoe Basin. These findings confirm that the plague is a natural part of the local ecosystem. Across the United States, plague is rare, with an average of only about seven human cases reported per year, mostly in rural areas of Western states like California, Arizona, New Mexico, and Colorado.
How Serious Is This?
When we hear "plague," the mind often goes straight to worst-case scenarios. However, it's crucial to differentiate between historical fears and present-day risks. The South Lake Tahoe case is one of bubonic plague, which has a low risk of person-to-person spread. The most serious form, pneumonic plague, is extremely rare and primarily a concern only if a patient's lungs become infected.
The rarity of cases and the effectiveness of modern medicine make the plague a manageable, not catastrophic, public health issue today. Early detection is key; the prompt use of antibiotics has saved countless lives. The real danger today isn't a widespread pandemic, but the potential for an untreated individual to develop a more serious form of the disease. For our mental wellness, navigating this requires a balance between informed concern and unnecessary anxiety. It's about acknowledging the reality of a threat without letting it spiral into a fear of imagined doom.
What People Should Know & Do
Awareness is our best defense against the plague. While the risk of infection is low, especially for those not engaging in outdoor activities in high-risk areas, a few simple, proactive steps can significantly reduce exposure.
Avoid contact with wild rodents, especially squirrels and chipmunks. Never feed them or get close enough to touch them.
When outdoors in rural or mountainous areas, use an insect repellent containing DEET on your socks and pants to deter fleas.
Protect your pets. Leash your dogs and keep them from approaching or playing with sick or dead rodents. Use flea control products on your pets as they can bring infected fleas into the home.
Monitor for symptoms. If you experience a sudden onset of fever, headache, chills, or swollen lymph nodes within two weeks of a potential exposure (like a camping trip), seek medical attention immediately and inform your doctor of your activities.
These are not precautions born of fear, but of common sense and a desire to be protective of your health and that of your loved ones.
Mind Over Fear: Lessons for Wellness
The news of old diseases resurfacing can be particularly unsettling. It can trigger anxiety, catastrophizing thoughts ("what if it spreads?"), or a sense of helplessness. It's an important reminder that our mental and physical health are deeply intertwined. When we feel a lack of control over our physical safety, our minds can react with worry and panic.
To counter this, practice grounding strategies. Acknowledge the feeling of fear, but then separate the real risk (a rare, treatable disease) from the imagined disaster (a widespread, unstoppable pandemic). Focus on what you can control: the preventative actions you can take, and your choice to stay informed without becoming consumed by worry. History shows that humanity has always adapted and survived in the face of epidemics. Today, we are better equipped than ever before—not only with advanced medical treatments but also with a greater understanding of our own psychological resilience.
Closing Reflection
The South Lake Tahoe plague case serves as a powerful, albeit subtle, reminder. It isn't a sign of a looming disaster, but a glimpse into the delicate balance of our world's ecosystems and our place within them. It highlights both our human fragility in the face of microscopic life and our incredible resilience through scientific advancement and collective knowledge.
At Made Up Mind, our goal is to cultivate clarity, balance, and preparedness in the face of fear. In a world full of headlines designed to provoke a reaction, we can choose to respond with informed calmness. The plague is no longer a story of inevitable doom, but a lesson in proactive health behavior and the power of mindfulness.
