What Is Viral Meningitis?
Viral meningitis is an inflammation of the membranes (meninges) surrounding the brain and spinal cord caused by viral infections. It is generally less severe than bacterial meningitis and often resolves without specific treatment. Common viruses causing viral meningitis include enteroviruses, herpes simplex virus, and mumps virus.
What Are the Symptoms of Viral Meningitis?
Common Symptoms:
- Headache
- Fever
- Stiff neck
- Sensitivity to light (photophobia)
- Nausea and vomiting
- Fatigue or weakness
- Muscle aches
- Irritability or confusion, especially in infants and young children
What Causes Viral Meningitis?
Viral meningitis is caused by infection with various viruses, most commonly:
- Enteroviruses (most frequent cause)
- Herpes simplex virus
- Mumps virus
- Varicella-zoster virus
- HIV
The virus usually spreads through respiratory secretions or fecal-oral routes.
How Is Viral Meningitis Diagnosed?
Diagnostic Tests:
- Physical exam checking for signs like neck stiffness
- Lumbar puncture (spinal tap) to analyze cerebrospinal fluid (CSF)
- Blood tests to identify viral infection
- Polymerase chain reaction (PCR) tests to detect viral DNA or RNA
- Imaging tests like MRI or CT scan if complications are suspected
How Is Viral Meningitis Treated?
1. Supportive Care
- Rest and hydration
- Pain and fever relief using acetaminophen or ibuprofen
- Avoid bright lights and loud noises to reduce discomfort
2. Antiviral Medications
- Sometimes used if herpes simplex or varicella-zoster virus is the cause
3. Hospitalization
- May be necessary if symptoms are severe or complications arise
Complications of Viral Meningitis
- Usually mild and temporary
- Rarely causes lasting neurological damage
- In some cases, seizures or hearing loss may occur
Living with Viral Meningitis: Tips for Recovery
- Get plenty of rest until symptoms improve
- Stay hydrated
- Follow medical advice closely
- Avoid contact with others if contagious
- Seek medical help if symptoms worsen or new symptoms develop
