You know its a busy morning when the daily tally of H7N9 is the sixth blog of the day.
Anyway, with a great deal of help from the newshounds at FluTrackers and Sharon Sander’s constantly updated and invaluable H7N9 Line Listing, we’ve five new cases reported out of Mainland China, along with the earlier reported Hong Kong Fatality (see CHP Announces 4th H7N9 Case In Hong Kong).
First stop, Zhejiang Province which reports three new cases today:

Although reported H7N9 cases have skewed heavily towards older patients - among those younger cases identified - we’ve seen relatively mild illness, which may be affecting the detection rate. Simply put, those with mild illnesses are less likely to seek medical care, get tested, and end up counted.
Whether younger people are actually infected less often than older people is something that probably can’t be firmly established until good, community wide seroprevalence studies can be conducted.
We may see additional cases announced later in the day, in which case I’ll post an update.
