ICD-10: A20.0

Bubonic plague, classified under ICD-10 code A20.0, is a severe infectious disease caused by the bacterium Yersinia pestis. This disease is primarily transmitted to humans through the bites of infected fleas, which often reside on rodents. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Etiology

Bubonic plague is caused by Yersinia pestis, a gram-negative bacterium. The disease is most commonly associated with rodent populations, particularly in areas where the plague is endemic. The bacterium can also be transmitted through direct contact with infected animals or through inhalation of respiratory droplets from infected individuals.

Symptoms

The hallmark of bubonic plague is the sudden onset of fever, chills, and weakness, typically accompanied by swollen and painful lymph nodes, known as buboes. These buboes are usually located in the groin, armpit, or neck and can vary in size. Other symptoms may include:

• Headache
• Nausea and vomiting
• Abdominal pain
• Muscle pain

If left untreated, bubonic plague can progress to septicemic or pneumonic forms, which are more severe and can be fatal.

Diagnosis

Diagnosis of bubonic plague is primarily clinical, supported by laboratory tests. Key diagnostic methods include:

• Culture: Isolation of Yersinia pestis from blood, lymph node aspirate, or other body fluids.
• Serology: Detection of antibodies against Yersinia pestis.
• PCR: Molecular techniques to identify the presence of the bacterium's DNA.

Treatment

Prompt antibiotic treatment is crucial for bubonic plague. Commonly used antibiotics include:

• Streptomycin
• Gentamicin
• Doxycycline
• Ciprofloxacin

Early intervention significantly reduces mortality rates associated with the disease.

Epidemiology

Bubonic plague is most prevalent in rural areas of Africa, Asia, and the Americas, particularly in regions with a history of plague outbreaks. The disease can occur in sporadic cases or in larger outbreaks, often linked to environmental factors that affect rodent populations.

Prevention

Preventive measures focus on reducing exposure to infected rodents and fleas. Key strategies include:

• Maintaining good sanitation and hygiene practices.
• Avoiding contact with wild rodents and their habitats.
• Using insect repellent to prevent flea bites.

Public health education is also vital in areas where the plague is endemic to raise awareness about the disease and its transmission.

Conclusion

Bubonic plague, classified under ICD-10 code A20.0, remains a significant public health concern in certain regions. Understanding its clinical presentation, transmission, and treatment options is essential for effective management and prevention of this potentially fatal disease. Early diagnosis and treatment are critical to improving outcomes for affected individuals.

Bubonic plague, classified under ICD-10 code A20.0, is a severe infectious disease caused by the bacterium Yersinia pestis. This condition is historically significant, often associated with pandemics such as the Black Death, and remains a public health concern in certain regions. Understanding its clinical presentation, signs, symptoms, and patient characteristics is crucial for timely diagnosis and treatment.

Clinical Presentation

Bubonic plague typically presents with a sudden onset of fever and chills, followed by the development of painful lymphadenopathy, known as "buboes."
