China - Hong Kong CHP reports some new H7N9 avian flu cases without details, some are previously known - April 21, 2017

I generally do not post this weekly summary report because it gives very little detail and the time frame overlaps with the very excellent Avian Influenza Weekly Report that is published with case details. The next avian influenza report is due April 25 and should give some insight to the below data. We have listed some of the below cases and some are new. Also due out next week is the very, VERY excellent periodic FAO H7N9 report.

I can't do anything with the below information. Some of it appears contradictory to local city/provincial reports.

It appears that the Jiangxi case mentioned in the China NHFPC report, via the Hong Kong CHP, in post 1 was first reported at the province level one month ago.

I have no idea if the time delay of one month between the provincial and national reporting is typical or not.
