Hebei Province - Credit Wikipedia
















#12,433


Hebei province, which practically encircles Beijing - as of Tuesday's HK CHP update - had reported just 4 H7N9 cases during this 5th epidemic wave, and only 8 since the virus first emerged in 2013. 
Like Beijing, and much of the rest of northern China, Hebei has been largely spared from dealing with H7N9. At least up until the past month or so.  But as the FAO map below indicates, increasingly this spring, H7N9 is turning up in northern China.

The brief (translated) official announcement reads:
