Abstract
Among 162 children referred with head injury (in a 3-year period) a viral meningoencephalitis was proven to be present in seven cases. Only one patient showed symptoms of infection before the accident. On admission classical signs of viral meningoencephalitis were absent or mixed with the complications of head injury. A diagnosis of viral meningitis/meningoencephalitis was documented by immunofluorescent demonstration of viral antigens in CSF cells and/or pattern of CSF cytology and/or conventional serological methods. Whether the trauma and the infection are coincidental or causally related can not be decided definitively. A hypothesis is presented suggesting diminished alertness in subclinical viral meningoencephalitis, leading to accident proneness.
