New H7N9 cases bring tally to 43

Another 5 H7N9 confirmations including a new death (n=11). Total of 43 cases - looks like 5/day is the new rate...an increase over time.

Given the approx 12-d gap between onset and test confirmation, it will still be a few days before we see an impact, if any, of Shanghai market closures and even more time for an impact from poultry culls.
