Beijing CDC Statement On Recent Locally Acquired H7N9 Infections










#12,388



As of last week's HK CHP Avian Flu Report Week 14, Beijing Municipality has reported 5 (mostly imported) H7N9 cases for this 5th epidemic season - like much of the rest of China, indicating a sharp increase in cases over the previous 4 years.  During the first 4 waves, Beijing had been largely spared,  averaging just over 2 cases per winter.

Last Friday, Beijing indicated a 6th case had been reported (see here), but provided no details.

Over the weekend Beijing's Center For Disease Control released the following statement which jumps that number up to 7 cases. Of these, were 3 locally acquired and 4 were imported from surrounding provinces.

The translated syntax then become a bit more challenging, as it goes on to describe what appears to be Beijing's first cluster (2 cases) of H7N9 infection, which they state had a `common exposure history'.  Details on this shared exposure are not provided.
 
 The CDC then warns that the risk of seeing additional imported cases remains high, and more locally acquired cases (and clusters) are possible.
