Encephalitis due to Herpes B virus – http://id.who.int/icd/entity/1018065824

An inflammatory process of the brain, frequently with evidence of meningeal involvement, due to infection by Herpes B virus, endemic in macaque monkeys. The clinical manifestations are usually acute, but may be subacute, with fever and variable combinations of convulsions, impaired mental state, and focal deficits. The spinal fluid may show a cellular reaction and elevated protein. Diagnosis is by neuroimaging, spinal fluid analysis and culture, PCR, and serologic tests.
