Viral Meningitis: Clinical Features and Rehabilitation Approach

Introduction

Viral meningitis is an inflammation of the meninges caused by viral infections. It is generally less severe than bacterial meningitis but can still lead to remarkable discomfort and functional limitations, especially in vulnerable populations such as children and immunocompromised individuals.

Definition

Viral meningitis is defined as an infection-induced inflammation of the protective membranes (meninges) surrounding the brain and spinal cord, most commonly caused by viruses such as enteroviruses, herpes simplex virus, and arboviruses.

Clinical Features

• Acute onset of fever and headache
• Neck stiffness and photophobia
• Typically, a self-limiting course in most cases
• Mild to moderate neurological symptoms
• Less severe progression compared to bacterial meningitis

Signs and Symptoms

• Fever, chills, and malaise
• Nausea and vomiting
• Headache and neck rigidity
• Sensitivity to light (photophobia)
• Altered mental status (mild confusion)
• Positive meningeal signs 
• Generalized fatigue and weakness

Complication

• Persistent headache and fatigue
• Seizures (uncommon)
• Cognitive difficulties (rare)
• Dehydration due to vomiting
• Secondary infections in immunocompromised patients
• Rare neurological deficits

Risk Factors

• Weakened immune system (e.g., HIV infection, cancer, immunosuppressive therapy)
• Infants and young children (higher susceptibility)
• Close contact with infected individuals (schools, households, daycare centers)
• Elderly population (reduced immunity)
• Poor hygiene and sanitation
• Exposure to contaminated food or water (fecal–oral transmission)
• Mosquito or tick exposure (arboviral infections)
• Seasonal factors (higher incidence in summer and early autumn for enteroviruses)
• Lack of vaccination (e.g., measles, mumps, varicella)
• Travel to endemic areas
• Overcrowded living conditions
• Chronic illnesses (e.g., diabetes, kidney disease)

Physiotherapy Management

• Early Mobilization: Prevents deconditioning and improves circulation
• Positioning: Promotes comfort and decreased neck stiffness
• Respiratory Care: Breathing exercises to maintain lung function in bedridden patients
• Fatigue Management: Gradual activity pacing and energy conservation techniques
• Gentle Range of Motion (ROM): Prevents joint stiffness and muscle tightness
• Functional Training: Restoration of daily activities as recovery progresses
• Patient Education: Importance of rest, hydration, and gradual return to activity

Conclusion

Viral Meningitis is typically a self-limiting condition with a favorable prognosis. However, early diagnosis, supportive care, and appropriate physiotherapy interventions are important to enhance recovery, decrease complications, and restore functional independence.
