Study finds new bird flu virus jumped directly from chickens to humans

As I posted earlier...keep in mind that there were no findings of H7N9 in wild birds tested in Beijing, as the results came out yesterday, posted here, excerpt of that article:
Wild birds are never detected the H7N9 virus
  Morning News (chief reporter Cui) Beijing Municipal Bureau of Parks, said yesterday that as of now, the city is not detected from wild birds H7N9 influenza virus nucleic acid positive.
  City Landscaping Bureau wildlife rescue center before 347 wild bird samples for testing, most of the samples for the public worried about the droppings of wild birds. The test results released yesterday, the H7N9 influenza virus nucleic acid in the sample of 347 wild birds were negative.

Chinese scientists have for the first time found strong evidence of how humans became infected with a new strain of bird flu: from chickens at a live market.
Chinese scientists compared swabs from birds at markets in eastern China to virus samples from four patients who caught the new H7N9 virus. The scientists found the virus from one patient was nearly identical to one found in a chicken. The research was published online Thursday in the journal Lancet.
Finding definitive proof of how patients were infected is very difficult and experts have so far struggled to find examples of the virus in birds. Despite taking nearly 48,000 samples from birds in live markets, Chinese officials found only 39 tested positive for H7N9. Experts had suspected birds in live markets to be the source of infection but were not sure if other animals or wild birds might also be responsible.
