Fourteen cases of polioviruses were isolated from the paralyzed children. Of these, 10 isolates were of type one, 2 type two and 2 type three. Among the healthy children two polioviruses were isolated, one type 1 and one type three. The importance of vaccination against poliomyelitis is emphasized.
