ICD-10 Code A85.1 | Adenoviral encephalitis Symptoms, Diagnosis, Billing

Common symptoms include fever, headache, confusion, seizures, and altered mental status. Patients may also present with a history of recent respiratory illness.

Diagnosis is typically made through clinical evaluation, supported by imaging studies such as CT or MRI, and laboratory tests including PCR for adenovirus.

Adenoviruses can spread through respiratory droplets and contact with contaminated surfaces. Precautions should be taken to prevent transmission, especially in outbreak settings.

Treatment primarily involves supportive care, including hydration and symptom management. There are no specific antiviral treatments for adenoviral infections.
