In 1976-7 26 cases of paralytic poliomyelitis were notified, of which 6 were vaccine-associated. Of the 20 non-vaccine-associated cases, 6 were due to type-1 poliovirus, the type usually associated with outbreaks. The most important factor in the increase was the occurrence of poliomyelitis in unvaccinated persons.
