[Meningitis caused by enteroviruses. Clinical and virological study of several sporadic cases in adults].

In the course of seven years (1968--1974) viral investigations were carried out in 212 casese of meningitis; predominantly Coxsackie viruses and sometimes ECHO viruses were isolated from 80 cases (37.73%). No polioviruses were isolated. Analysis of the clinical data (onset, general conidtion, evolution, complications, psychical, renal and cardiac disturbances etc.) revealed the severe aspect of these cases. The aspect and evolution of the cerebrospinal fluid showed the presence in almost 25% of the cases of an increased number of cellular elements of more than 1 000/mm3 and albumin sometimes far above normal values with a slow return (3--4 weeks). The complex therapy applied in more than half the cases demonstrates the necessity of attentive follow up of these cases of viral meningitis.
