Results A total of 4256 HFMD cases, including 35 severe cases and 3 deaths, were reported, the annual average incidence was 99. 57/lakh, the case fatality was 0. 70%0. The incidence peak of HFMD was during May-July, but the incidence peaks in 2011 and 2012 occurred earlier than before, and the sub peaks occurred during October-December. The cases aged 0 -5 years accounted for 96. 08% of the total. The male to female ratio of the cases was 1.57： 1. Most cases were preschool aged children. Among the reported cases, 253 were laboratory confirmed, accounting for 5.94% of the total, Among the laboratory confirmed cases, EV71, Cox A16 and other entericvirus infections accounted for 56. 92%, 24. 50% and 18. 58% respectively. The predominant pathogens causing HFMD changed from EV71 to Cox A16 and other entericviruses during 2011 -2012.
