[Enteroviruses in the XX and XXI centuries]

The modern view of the role of enteroviruses in the eradication of poliomyelitis is presented. Enteroviruses were discovered in the XX century. In the 1950s they caused great epidemics of poliomyelitis and serous meningitis in many countries of the world. The introduction of oral poliomyelitis vaccine (OPV) into medical practice made it possible to eliminate the epidemics of poliomyelitis in a short time. Poliomyelitis morbidity was reduced to sporadic cases and in a number of regions disappeared. OPV produced non-specific influence also on the epidemics of serous meningitis, as well as on a case incidence. The eradication of poliomyelitis viruses and the cessation of immunization with OPV will not result in eradication of paralytic diseases. Paralytogenic viruses of 20 serotypes circulate in nature, and some of these viruses are capable of causing the outbreaks of severe paralytic diseases. The authors propose either to retain immunization with OVP as tour immunizations with monovaccine of type 2, or to create new live enterovirus vaccines on the basis of avirulent enterovirus strains.
