[Non-poliomyelitis viruses in Poland 1982-1987].

Diseases caused by non-polio enteroviruses (ENP) are diagnosed virologically and serologically in 17 Virology Laboratories of the Province Sanitary-Epidemiological Stations and the Department of Virology, State Institute of Hygiene. The results of these investigations are available in the form of documentation including the type of the isolated virus, the result of serological investigation, the date of disease onset, the clinical diagnosis, the age and sex of the patient. These data were analyzed in this work. Overall, the aetiological role of ENP was established in 5258 cases. The isolated strains belonged to 32 serotypes: echoviruses type 1-9, 11-15, 17-20, 24-27, 29. 31, Coxsackie B types 1-6 and A type 9. Ten predominating serotypes--echoviruses type 4,6,7,9,30, Coxsackie B types 2-5 and A type 9--accounted for 92% of all isolates. The epidemic types (over 25% of isolates) in a given year were echoviruses type 4,6,7,30. On the basis of these observations from 14 years 4 models of cyclic occurrence of dominant serotypes in Poland were established. Acute central nervous system infections accounted for nearly 80% of all diseases caused by ENP, cardiac diseases for 15%, and other diseases of milder course, less frequency suspected of this aetiology and less frequently diagnosed, accounted for 5%.
