We compared the clinical and epidemiologic characteristics for the first three waves of virus circulation. Methods The first wave was defined as reported cases with onset dates between March 31-September 30, 2013, the second wave was defined as October 1, 2013-September 30, 2014 and the third wave was defined as October 1, 2014-September 30, 2015. We used simple descriptive statistics to compare characteristics of the three distinct waves of virus circulation. Results In mainland China, 134 cases, 306 cases and 219 cases were detected and reported in first three waves, respectively.
