A87.1
Adenoviral meningitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Adenoviral meningitis is a viral infection characterized by inflammation of the membranes surrounding the brain and spinal cord, known as the meninges. Caused by the adenovirus, this condition is more common in children but can affect individuals of any age. Recognized under the ICD-10 code A87.1, adenoviral meningitis is usually self-limiting, meaning it often resolves without specific antiviral treatment. Understanding its causes, symptoms, diagnosis, and management can help in better awareness and early identification.
Causes & Symptoms
Clinical Causes: The primary cause of adenoviral meningitis is infection with adenoviruses, which are a group of common viruses that can cause respiratory, gastrointestinal, and other illnesses. Transmission occurs through contact with respiratory secretions, fecal matter, or contaminated surfaces, especially in crowded environments or institutions like schools and hospitals. Close contact with an infected individual increases the risk of spreading the virus to others. Adenoviruses are hardy and can survive on surfaces for extended periods, facilitating transmission. Though less common, infective spread can also occur through aerosols during coughing or sneezing.
Key Symptoms: Sudden onset of high fever Headache and sensitivity to light (photophobia) Stiff neck Nausea and vomiting General discomfort or malaise Neck stiffness and muscle pain Altered mental status (less common in mild cases) Sometimes, symptoms of respiratory infection such as cough and sore throat Lethargy or fatigue Irritability, especially in young children
Diagnostic & Treatment
Diagnosis Path: Diagnosing adenoviral meningitis involves a combination of clinical evaluation and laboratory testing. Healthcare providers may perform the following:
Treatment Protocols: Since adenoviral meningitis is caused by a virus, treatment mainly involves supportive care aimed at relieving symptoms and ensuring adequate rest and hydration. Specific antiviral medication is generally not used unless directed by a healthcare provider. The standard management includes:
