Abstract:
Objective To investigate the level of measles antibody in physical examination population in Jinshan District, and provide evidence for measles immunization prevention and control in different populations. Methods The sera of physical examination population aged 15 years and older in Jinshan was collected.The titer of IgG antibody against measles was measured by using enzyme-linked immunosorbent assay (ELISA).Statistical methods were used to compare and analyze the data. Results The overall positive rate of measles antibody in physical examination population aged 15 and older in Jinshan was 70.74%, and the antibody protection rate was 17.56%.There was no significant difference in the distribution of measles antibody between different genders, or local population and migrant population (P>0.05).There was no significant difference in the positive rate of measles antibodies between different age groups (P>0.05), but the protection rate was statistically significant(χ2=44.53, P < 0.05).There was no statistically significant difference in the distribution of antibody levels between residents and migrants in all age groups.The rate of measles antibody protection in the 15-24 age group was the lowest, only 9.60%, and the antibody protection rate increased with age.The rate of measles antibody protection in the 65-95 age group was the highest, 25.62%. Conclusion The immunization level of measles antibody in physical examination population in Jinshan District is at a low level, and there is a potential risk of measles outbreak.In particular, it is imperative to focus on strengthening the measles immunization work in 15-24 age population.It is recommended to promote adult measles immunization program.
