Study supports poor H7N9 transmission - from anything!

A new paper in by J. Han et al. Emerging Microbes and Infection concludes that neither 2 vendors in an H7N9-positive poultry market visited by the H7N9-positive patient (our Case#10, also studied in recent Lancet article) nor his close contacts, were WHO RT-rtPCR positive. 

So picking up H7N9 is certainly not a frequent thing. Also supported by the few cases that have been identified considering the population in these areas that move through and interact with birds and the markets. 

Also, once you have it, transmitting H7N9 it seems to be an infrequent event.
