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 5th report of this winter season, which are summarized below.
For October: 2 H7N9 cases, 1 death 0 H5 Cases
For November: 6 H7N9 cases, 0 deaths 0 H5 Cases
For December: 106 H7N9 cases, 20 deaths 0 H5 CasesFor January: 192 H7N9 cases, 79 deaths 0 H5 Cases
For February 160 H7N9 cases, 61 deaths 0 H5 Cases
5th Epidemic Wave 466 H7N9 cases, 161 deaths 0 H5 Cases
As a cut off date for this report isn't stated, and case reports from February may still be coming in, these numbers should be viewed as approximate, and subject to revision. Cases continue to be reported in March, albeit at a lower rate, so we are already likely above the 500 mark for the season.
Although a record number of H7N9 cases, there is nothing in these numbers to suggest sustained or efficient transmission of the virus.
That said, the virus continues to evolve and spread, we continue to hear rumors of under reporting of cases, and while slowing, there may be yet several more months to this year's epidemic. So we continue to watch the situation closely.
February 2017 (at 0:00 on the February 1, 2017 to February 28 24), the country (excluding Hong Kong, Macao and Taiwan, the same below) reported a total of 485,649 cases of legal infectious diseases, died 1409 people. Among them, the Group of infectious diseases as plague, cholera incidence and deaths have been reported. B infectious diseases infectious atypical pneumonia, diphtheria, polio and no human infection with highly pathogenic avian influenza morbidity, mortality reports, the remaining 22 infectious diseases were reported incidence of 278,526 cases, 1397 people died. Before the reported incidence of the top five diseases were viral hepatitis, tuberculosis, syphilis, gonorrhea, and bacillary and amoebic dysentery, accounting for 96% of the total reported cases of class B infectious diseases.
Over the same period, Class C infectious diseases filariasis morbidity, mortality reports, the remaining 10 infectious diseases were reported incidence of 207,123 cases, 12 people died. Before the reported incidence of the three diseases were other infectious diarrhea, hand-foot-mouth disease and influenza, accounting for 94% of the total reported cases of class C infectious diseases.
This total of 160 cases is actually pretty close to what we were expecting to see, based on the fragmented reports we'd received during the month of February.
While of admittedly limited value, this report is the only monthly summary of Mainland China's H7N9 cases we get from the NHFPC, and serves as China's `official' count for each epidemic season.
