METHODS: Measles antibody surveillance (M-lgM) was performed on 912 suspected serum samples collected over the past five years using enzyme-linked immunosorbent assay. Results: A total of 912 blood samples were collected from Xuchang City in the past five years. The collection rate was 80.14%, of which 618 were positive for M-IgM.
