Clinical Classification Guidelines
Medical Intelligence & Overview
Cellulocutaneous plague, classified under ICD-10 code A20.1, is a rare infectious disease caused by the bacterium Yersinia pestis. This form of plague affects the skin and underlying tissues, leading to severe skin infections and tissue necrosis if not treated promptly. Historically linked to pandemics, today it remains a concern mainly in certain regions and requires specific medical attention.
Causes & Symptoms
Clinical Causes: Bacterial infection with Yersinia pestis Transmission typically occurs through flea bites from infected fleas Spread can also occur through contact with infected animals or tissues Inhalation of contaminated respiratory droplets is less common but possible
Key Symptoms: Pain, swelling, and redness in the affected area Formation of buboes, which are swollen lymph nodes Fever and chills Headache and fatigue Developing skin ulcers that may become necrotic In severe cases, symptoms may progress to systemic illness with sepsis
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves clinical examination of symptoms combined with laboratory tests. These tests include blood cultures, identification of Yersinia pestis through microscopy, serological testing, and molecular techniques like PCR. Rapid diagnosis is crucial to prevent serious complications and improve prognosis.
Treatment Protocols: Treatment typically involves antibiotics such as streptomycin, doxycycline, or gentamicin administered promptly. Supportive care may include hospitalization, fluid management, and measures to control symptoms. Early intervention significantly reduces risks of complications and mortality.
