Analysis on Surveillance of Polio Laboratory in Anhui in 1989-2000

The paper reported detection results of Anhui polio laboratory since 1989. 1856 AFP cases were collected stool samples in 1989-2000 in Anhui. Polioviruses were isolated from 178 cases. The isolation rate was 9.5%. Non-polio viruses were isolated from 318 cases. The isolated rate was 17.13%. There were 490 viruses in total, general isolation rate was 26.40%. 1953 stool samples were collected from the contacts of 407 AFP cases in 1994-1998. Polio virus were isolated from the contacts samples of 5 AFP cases (1.23%), non-polio viruses were isolated from the contacts samples of 107 AFP cases (26.29%). 685 serum samples were collected to test antibody concentration of polio in 1990, 1993 and 1997, the positive rate of polio antibody reached 99%.
