[Surveillance on poliomyelitis neutralization antibody level in the border areas in Jilin province].
OBJECTIVE
This project is designed for understand poliomyelitis (Polio) neutralization antibody level in the the border areas in Jilin province.


METHODS
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.


RESULTS
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.


CONCLUSIONS
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.
