A20.2
Pneumonic plague
Clinical Classification Guidelines
Medical Intelligence & Overview
Pneumonic plague, classified under ICD-10 code A20.2, is a serious infectious disease caused by the bacterium Yersinia pestis. It primarily affects the lungs and can spread rapidly from person to person through respiratory droplets. Though rare today due to modern medicine and public health measures, it remains a critical health concern historically and in specific regions prone to outbreaks. Prompt recognition and treatment are crucial to prevent severe complications and transmission.
Causes & Symptoms
Clinical Causes: Bacterial infection with Yersinia pestis bacteria Transmission from infected animals like rodents or fleas to humans Human-to-human spread through coughs and sneezes Exposure to contaminated respiratory droplets in close contact with an infected individual
Key Symptoms: Fever and chills Cough, often with bloody or sputum-filled secretions Shortness of breath or difficulty breathing Chest pain Weakness and fatigue Rapid progression to severe respiratory distress if untreated
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves clinical assessment and laboratory testing. Healthcare providers may order samples of sputum, blood, or tissue to identify Yersinia pestis. Chest X-rays can help assess lung involvement. Timely diagnosis is vital for effective management and containment.
Treatment Protocols: Treatment of pneumonic plague typically requires immediate administration of specific antibiotics such as streptomycin, gentamicin, doxycycline, or ciprofloxacin. Supportive care may include oxygen therapy, fluids, and respiratory support in severe cases. Isolation precautions are essential to prevent spread, and public health authorities may conduct contact tracing and prophylactic treatment for exposed individuals.
