[Evaluation on the effect of supplementary immunization for poliomyelitis elimination in Hainan province].
We appraised the effect on poliomyelitis elimination programme in Hainan Province, based on data as incidences of poliomyelitis in last years, the routine immunization and the activities on National Immunization Day (NID) and Provincial Immunization Day (PID). The result indicated that the effect of NID in 1993/1994 was remarkable. In Hainan Province, there has been no poliomyelitis case caused by wild strain of poliovirus since 1994. Laboratory data also demonstrated that NID could break the circulation of wild strain of type I poliovirus. We found that routine immunization alone could not effectively eliminate poliomyelitis but other activities of NID must be carried out in order to form an immunity-barrier within a short period.
