Health officials in Colorado have confirmed that a person in Pueblo County has contracted the plague. The exact source of the infection is currently unknown, but the disease is caused by the bacterium Yersinia pestis, which is typically transmitted through flea bites. Plague can also be transmitted to humans if they handle the tissue or body fluids of an infected animal.
There are different types of plague, with the most common being bubonic plague. This type of plague infects the lymphatic system, causing swollen lymph nodes known as buboes. Other symptoms include fever, headache, and chills. In more severe cases, the plague can infect the lungs and cause pneumonic plague, which is considered more dangerous.
Historically, plague has caused widespread pandemics with high casualty rates, such as the infamous “Black Death” in the 1300s. However, with early detection and treatment with antibiotics, plague can be successfully treated. If left untreated, pneumonic plague is always fatal, while bubonic plague has a death rate of around 30% to 60%.
Health officials advise anyone experiencing symptoms of plague to seek medical attention immediately. Complications of the disease can include meningitis and septic shock. To prevent plague, the public is encouraged to take precautions such as eliminating rodent hiding places, avoiding contact with dead animals, and using insect repellent to prevent flea bites.
While plague cases are rare in the United States, with around seven reported cases each year, it is important to be aware of the symptoms and take preventive measures.
