Second wave of A(H7N9) cases in the People's Republic of China peaked in weeks 4-6, 2014

The graph below shows the frequency of A(H7N9) cases by week number (based onset date) since week 47 in 2013.  The infection rate started to increase in the last week of December, 2013 and the first week of January 2014. The case count continued to climb and peak between weeks 4 through 6. Since then, the number of H7N9 cases has been declining perhaps signaling an end to the second wave of H7N9 infections in China.
