Objective To evaluate the maintenance of poliomyelitis-free status in Tianjin in 2003. Methods used to describe epidemiological methods. Results AFP cases monitoring system in Tianjin reported 17 AFP cases in 2003. According to the case classification criteria, all were polio-negative cases. The incidence of non-polio AFP cases in children <15 years old was 1. 2 7/10 million. The sampling rate of qualified stool specimens was 100%. Other monitoring indicators met the requirements of the World Health Organization and the Ministry of Health. The city’s routine immunization was carried out with 209,714 oral poliovirus (OPV) and 99.23% of the basic immunization reports, and the survey of 2,156 children in the city was 98.58% . From December 5 to December 10, 2003, and from January 5 to January 10, 2004, leak detection and replanting activities mainly involving floating children were carried out in the floating population centers, the urban-rural integration areas and the routine immunization areas. A total of 175 30 migrant children were investigated. Among them, 4 364 were detected as non-immunized or under-immunized children 12 months of age, accounting for 24.9% of migrant children surveyed, with a total of 24,670 OPVs in two rounds. Two rounds of quality assessment of a total of 3189 children surveyed, with the exception of 3 people refused to convince, did not find leakage of children. Conclusion Tianjin remains polio-free.
