NHFPC Announces 96 H7N9 Cases (47 Deaths) For Month Of March


While significantly lower than reported for February (160 Cases & 61 Deaths) - and despite the concerted efforts of both local and national authorities to reign in this year's  epidemic (see Chinese Premier Briefed On H7N9 - Urges Shut Down Of Poultry Markets) - the latest numbers released by China's NHFPC confirm that last month's H7N9 tally was at least triple that of any other March since the virus emerged in 2013.

Once a month, usually between the 10th and the 15th, China's  NHFPC (National Health & Family Planning Commission) releases a bare-bones listing of the previous month's reportable infectious diseases across Mainland China.
These summaries are very short - with an attached list of over 3 dozen infectious diseases - providing only country totals, and number of deaths recorded.

With their 5th H7N9  flu season beginning in October, today's is the 6th report of this winter season, which are summarized below. 
October          2 H7N9 cases,    1 death

November:       6 H7N9 cases,    0 deaths

December:   106 H7N9 cases,  20 deaths
January:       192 H7N9 cases,  79 deaths

February      160 H7N9 cases,   61 deaths

March            96 H7N9 cases,   47 deaths
5th Wave     562 H7N9 cases, 208 deaths
As a cut off date for this report isn't stated, and case reports from March may still be coming in, these numbers should be viewed as approximate, and subject to revision.  Cases continue to be reported in April, albeit at a lower rate, so we are closing in on the 600 case mark.

Although a record number of H7N9 cases, there is nothing in these numbers to suggest sustained or efficient transmission of the virus. 

That said, and as discussed in some detail yesterday (see NPR: A Pessimistic Guan Yi On H7N9's Evolution), there are deeply concerning signs that H7N9 continues to evolve in ways that may make it more difficult to contain or control. 

The (translated) text and a modified (highlight mine) excerpt from today's NHFPC report follows:
