Catching Up With FluTracker's H7N9 Case List

After last week's flurry of H7N9 reports (see HK CHP: China Reports An Additional 83 H7N9 Cases For December), official reports have once again slowed, but we continue to get reports suggesting the virus is still very much active in Eastern China.

The problem is, given the lack of details provided on these cases, matching up against earlier reports (equally devoid of detail), becomes a major challenge.

Trying to make sense of all of this  is Sharon Sanders of FluTrackers, whose H7N9 case list provides the best conservative listing of cases (with links to reports) publicly available. 

Since we last looked in on Monday, Sharon and the newshounds of FT have added 17 new cases.

FluTrackers 2013-16 Human Case List of Provincial/Ministry of Health/Government Confirmed Influenza A(H7N9) Cases with Links

#948 - Patient, 79, Kaili City, Quiadongnan, Guizhou province CHP rpt 16/1/17

#949 - Female, 36, [Zhang], hospitalized in critical condition, contact with poultry, Hengyang City, Hunan province

#950-957 - This line adds 8 cases and 1 death. Hong Kong CHP confirmed 11 cases & 2 deaths on Jan 17. We have 3 cases & 1 death listed above. Guangdong province CHP rpt 17/1/17 Death

#958-962 - This line adds 5 cases and 3 deaths. On January 16 Hunan province CDC announced case #949 and referred to a total of 8 cases/3 deaths for 2017. We have 3 of those cases listed above. 3 Death

#963-964 - The line adds 2 cases and 1 death. On January 18 Hunan province HFPC announced 10 total cases and 4 deaths so far for 2017.We have 8 of those cases and 3 deaths noted in lines above. Death

Given China's practice of belatedly announcing many of their cases in EOM epidemiology reports (released on or about the 10th of the following month), it is likely this only represents a portion of the cases detected over the past week or so.
