[Viral encephalitis--personal observations].

Forty-two cases of the viral encephalitis have been analysed clinically and epidemiologically. On the basis of a literature review and own observations the author discusses the aetiology, diagnosis, clinical course and treatment of encephalitis caused by viruses. An emphasis in the diagnostic methods (serodiagnosis and viral isolations) was presented. Attention is called to the early treatment with antiviral drugs.
