Poliovirus immunization situation in China

Summary

Following the introduction of the Expanded Programme on Immunization in China, poliomyelitis outbreaks were successfully controlled and poliomyelitis incidence greatly decreased. By 1988, the reported number of poliomyelitis cases decreased to 667 and China set the target of 1995 for eradication of poliomyelitis. In 1989 and 1990, however, epidemics recurred in many provinces of China. Poliomyelitis mainly occurs in unvaccinated and partially vaccinated children under the age of 4 years old. The geographic distribution of cases indicates that continuous low-level transmission of poliovirus is occurring throughout much of the country.
