Rare Pneumonia Case Claims Life in Coconino County
A resident of Coconino County recently passed away from an unusual instance of pneumonia. Dave Wagner, who directs the Institute for Pathogens and Microbiota at Northern Arizona University, discussed the plague’s life cycle and the ongoing research to create vaccines.
Understanding Plague in Northern Arizona
The plague primarily affects rodents and their fleas, and this has been the case for centuries. Infected rodents carry the bacteria Yersinia Pestis, and when fleas feed on these rodents, they can also become carriers of the bacteria. If those fleas bite another rodent, they transmit the infection. It’s a sort of ongoing cycle between these animals and the fleas.
Impact on Humans
In the United States, there are typically 5 to 10 cases of plague reported each year. The most common way humans get infected is through flea bites, leading to what’s known as bubonic plague. If left untreated, it can enter the bloodstream, potentially causing sepsis, and eventually lead to pneumonia. This disease is global, appearing in North and South America, Asia, and Africa, with Madagascar being a major area of research for the past 25 years.
Research Goals in Madagascar
Wagner aims to enhance diagnostic methods for detecting Yersinia Pestis quickly, which is crucial since infections can be effectively treated with antibiotics if caught early. Untreated, however, it can be deadly.
Advice for Local Residents
He emphasizes that while deaths are tragic, instances of plague are extremely rare. People should be more concerned about other health issues. It’s wise to watch out for pets—dogs and cats might carry fleas, so using flea collars can help. Symptoms of the plague can resemble other illnesses, like fever and fatigue, so anyone experiencing these should definitely consult a healthcare provider.
Future Research Directions
Wagner expresses excitement about the potential development of a plague vaccine, particularly since it mainly impacts poorer populations worldwide. Despite the seriousness of this disease, efforts to create a vaccine have not been substantial. He hopes for advancements to ensure that those who are most at risk can access it.
Final Thoughts
In closing, Wagner expresses his gratitude for the opportunity to share this information.
