title: [Analysis on poliomyelitis cases in Inner Mongolia in 1990-1993].
abstract: Out of 97 AFP cases, 68 were confirmed polio in Inner Mongolia in 1990-1993, in which 44.12% were diagnosed according to laboratory results. In this period, 13 strains of polio virus were isolated and identified from the stool samples of 62 AFP cases. The etiological results suggested that there was no dominant strain of polio virus in the whole region. Serological results showed that the positive rates of IgM antibody against polio virus were 75%, 26% and 0% in 1990, 1991, 1993 respectively which seemed to have a declining trend.
