Se ha aislado poliovirus de casos de poliomielitis paralítica de la epidemia de Iquitos. De siete muestras de heces, se aisló un poliovirus de tipo I, dos de tipo II y dos del tipo III. También se aisló un virus del tipo III de un contacto asintomático. Se presume que la fuente de infección pudo provenir de un servicio de agua recientemente contaminado con materias fecales; ésta puede ser la causa de la aparición de los tres tipos de virus en una sola epidemia. Se airló asimismo poliovirus de pacientes de poliomielitis paralitica del Hospital del Niño de Lima. En esos casos se recuperó un virus del tipo III y cuatro del tipo I.
Polioviruses were isolated from cases of paralytic poliomyelitis which occurred in an Iquitos epidemic. From seven faces specimen, one Type I, two Type II, and Type III polioviruses were recovered. Also, on Type III, virus was recovered from a contact who had no clinical symptoms. It is postulated that the source of infection could have been a common water supply recently contaminated with fecal material; this could account for the appearance of all three virus types in a single epidemic. Polioviruses were also isolated fron paralytic poliomyelitus patients in the Hospital del Niño de Lima, Four Type I and one Type III viruses were recovered from these patients.
