Case definition for encephalitis in the Emerging Infections Program Encephalitis Project, 1997–2010*

Criteria
Major criterion (required): Altered mental status lasting ≥24 h
Plus >1 of 6 minor criteria:
1. Fever ≥38°C occurring ≤72 h before or after hospital admission
2. Seizures
3. Focal neurologic deficits not previously present on examination
4. Cerebrospinal fluid pleocytosis (≥5 leukocytes/mm3)
5. Abnormal electroencephalogram
6. Abnormal neuroimaging (computed tomography or magnetic resonance imaging) representing an acute process

*International Encephalitis Consortium case definition requires the presence of the major criteria plus ≥3 minor criteria for confirmed/probable; ≥2 for probable encephalitis (4).
