  1. What are the symptoms of JE?

    Most infections cause no symptoms. Mild infections cause a fever with headache.  Severe infection is rare, but develops rapidly, and causes intense headache, high fever, neck stiffness, disorientation, tremors, seizures (especially in infants), spastic paralysis, and coma.  Severe disease is deadly in 25% of infections.

  2. How is JE treated?

    Therapy for symptomatic JE infection is supportive.  Patients often require tube feeding, airway management, and anticonvulsants for seizure control.  No clearly effective antiviral agents exist.
