Characterization of a virus isolated from the cerebrospinal fluid of patients with epidemic neuropathy.
A previously unknown disease, termed epidemic neuropathy (EN), occurred in Cuba between 1991 and 1993. When samples of cerebrospinal fluid (CSF) from 45 patients with EN and 11 controls were inoculated into cultures of VERO cells, almost all (93%) of the samples from the cases of EN but only one (9%) of the control samples produced a slowly progressing cytopathological effect (CPE). Although the results of other studies indicated the presence of a picornavirus-like virus in CSF samples from EN cases, the CPE and other physico-chemical characteristics observed were not those expected of picorn-viruses. Several aetiological factors may have contributed to EN but at least one virus could have played a major role.
