Tularemia in Colorado: What to Know About the "Zombie Rabbit" Disease

Colorado's stunning natural beauty attracts millions of visitors each year, but alongside the breathtaking landscapes lurks a potential threat: tularemia, often ominously nicknamed the "rabbit fever" or even the "zombie rabbit" disease. While not a widespread epidemic, understanding this bacterial infection is crucial for anyone spending time outdoors in the Centennial State. This article will delve into the facts surrounding tularemia in Colorado, providing vital information to protect yourself and your family.

What is Tularemia?

Tularemia is a bacterial infection caused by Francisella tularensis, a bacterium that can infect a wide range of animals, including rabbits, hares, squirrels, and rodents. These animals often serve as reservoirs for the disease. Humans contract tularemia through various routes, most commonly:

• Direct contact: Handling infected animals (including carcasses), their tissues, or their droppings. This is a significant risk for hunters, trappers, and those working outdoors.
• Insect bites: Ticks, deer flies, and mosquitoes can transmit the bacterium. This makes spending time in wooded or grassy areas a potential risk.
• Inhalation: Breathing in contaminated dust or aerosols, particularly in areas with high rodent populations.
• Ingestion: Consuming contaminated food or water. This is less common but still a possibility.

Symptoms of Tularemia:

Symptoms of tularemia can vary depending on the route of infection, but generally appear one to 14 days after exposure. These can include:

• Ulceroglandular tularemia: This is the most common form, characterized by a skin ulcer at the site of infection, along with swollen and painful lymph nodes.
• Glandular tularemia: Swollen lymph nodes without an ulcer.
• Oculoglandular tularemia: Infection of the eye, leading to conjunctivitis and swollen lymph nodes.
• Oropharyngeal tularemia: Infection of the mouth and throat, causing sores and swollen lymph nodes.
• Pneumonic tularemia: Infection of the lungs, resulting in pneumonia-like symptoms such as cough, chest pain, and shortness of breath. This is the most serious form.
• Typhoidal tularemia: A systemic infection resembling typhoid fever, causing fever, chills, and weakness.

Treatment and Prevention:

If you suspect you have tularemia, seek immediate medical attention. Antibiotics, such as streptomycin or gentamicin, are highly effective in treating the infection. Early diagnosis and treatment are crucial for preventing serious complications.

Prevention is key:

• Wear protective clothing: When handling animals or working outdoors, wear long sleeves, long pants, gloves, and insect repellent.
• Avoid contact with potentially infected animals: Don't handle wild animals, and always wear gloves when handling carcasses.
• Practice good hygiene: Wash your hands thoroughly after being outdoors, particularly after handling soil or potentially contaminated materials.
• Use tick and insect repellents: Apply EPA-registered repellents to exposed skin and clothing.
• Cook meat thoroughly: Ensure all wild game is cooked to a safe internal temperature to kill any potential bacteria.

Tularemia in Colorado: Specific Considerations

Colorado's diverse ecosystems provide habitats for various animals that can carry Francisella tularensis. Hunters, hikers, campers, and anyone spending time in natural areas should be aware of the risks and take appropriate precautions. The Colorado Department of Public Health and Environment (CDPHE) provides valuable resources and updates on tularemia outbreaks within the state. [Link to CDPHE website here].

Conclusion:

While tularemia isn't a common disease, it's essential to be aware of its potential dangers, especially if you frequently engage in outdoor activities in Colorado. By understanding the risks, symptoms, and preventative measures, you can significantly reduce your chances of contracting this "zombie rabbit" disease and enjoy the beauty of Colorado's landscapes safely. Remember, early detection and prompt treatment are key to a successful outcome. Stay informed, stay safe, and enjoy the great outdoors responsibly.
