[Type 4 echovirus meningitis in childhood. Epidemiologic and clinical aspects apropos of an epidemiologic outbreak].

In the first half of 1988 we observed 13 cases of lymphocytic meningitis from which echovirus type 4 was isolated in the CSF. We found a higher infection rate in the 6-9 years old group (54%) and in the masculine sex (69%). Almost all of the cases occurred during the springtime. The clinical and CSF characteristics of this epidemic do not differ much from those that have appeared in the literature. Throughout 1988, in our hospital, 46 cases of lymphocytic meningitis took place and in 20 of them an etiologic diagnosis was done. We think that the introduction of enterovirus cultures can help to know the etiology of many of these cases of meningitis since this virus is responsible for a great part of them.
