METHODS To collect the surveillance data of HFMD in Qinghai Province in 2009 and the distribution characteristics were analyzed by de- scriptive epidemiological method. RESULTS It showed that 2436 cases of HFMD were reported in Qinghai Province in 2009, the reported incidence rate was 43.95/100 000, and no cases of severe and death all year. The HFMD cases were mainly dis- tributed in the east of Qinghai Province and were reported every month, and June was a peak incidence period. The ehildcare and scattered children with 3 years old were mainly infected. And the male cases infected were more than females. From the re- sults of pathogen surveillance, it showed that positive rate of Enterovirus 71 （EV71） was 57.73%, neutralizing antibody posi- tive rate was 37.60%, and positive rate of Coxsackie virus A16 （Cox A16） was 42.27%. CONCLUSION The incidence of HFMD has significant differences in regional, seasonal, age and gender in Qinghai Province in 2009, and the pathogens were EV71 and Cox A16 in children, of which EV71 was major.
