A20.3
Plague meningitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Plague meningitis is a severe form of plague caused by the bacterium Yersinia pestis. It affects the membranes surrounding the brain and spinal cord, leading to inflammation. Though rare, it is life-threatening if not diagnosed and treated promptly. This condition is classified under ICD-10 code A20.3 and requires immediate medical attention to prevent serious complications.
Causes & Symptoms
Clinical Causes: Bacterial infection with Yersinia pestis Transmission through bites from infected fleas or contact with infected animals Rarely, inhalation of infected droplets during close contact with an infected person or animal
Key Symptoms: High fever Severe headache Stiff neck Sensitivity to light Nausea and vomiting Altered mental status or confusion Rigidity and swelling at the site of the bite (if applicable) Signs of systemic infection such as chills and weakness
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation and laboratory tests. Physicians may perform cerebrospinal fluid (CSF) analysis to identify the bacteria, along with blood tests for Yersinia pestis. Cultures from blood and CSF samples help confirm the presence of the bacteria. Imaging studies may also be used to assess brain involvement.
Treatment Protocols: Effective treatment typically includes antibiotics such as streptomycin, gentamicin, doxycycline, or ciprofloxacin, administered promptly upon diagnosis. Supportive care in a hospital setting, including fluids and medications to manage symptoms, is crucial. Early intervention significantly improves the prognosis and reduces the risk of long-term neurological damage.
