It was only a matter of time since the market testing has been revealing signs of H7N9 circulating.
For 47M...
"The Guangdong health authorities have on patients 60 close contacts under medical surveillance, not currently found exception."
For 71M...
"The Guangdong health authorities have on patients 65 close contacts under medical surveillance, not currently found exception."
So the contacts are under surveillance but I strongly suspect that if that surveillance was to extend to actual RT-PCR testing, then we would likely see some detections amongst those cases. Symptoms alone do not the full story tell.
My source was Twitter via @pandemic_news and associated blog post here.
