Objective: This project is designed for understand poliomyelitis (Polio) neutralization antibody level in the the border areas in Jilin province.
Method: 263 serum samples were collected from age groups of under 1-year-old, 1-2, 3-4, 5-6, 7-14, 15-19 and above 20-years-old. Microplate neutralization test was used to determine antibody level.
Result: Positive rates of neutralization antibody against Polio type I, II, III were 94.98%, 94.59%, 92.28%. The geometric mean titre of Polio type I, II, III were 1:40.53, 1:29.68, 1:20.71 respectively,which was decreased with the age increasing.
Conclusion: The population especially the population under 15-years-old lived in places that near the border in Jilin province had good immunity barriar against poliomyelitis.
