Study confirms poultry as source of H7N9 bird flu

PARIS (AFP) - Chinese researchers reporting in The Lancet on Thursday confirmed poultry as a source of H7N9 flu among humans but said they found no evidence of person-to-person transmission.

A probe into four cases of human H7N9 influence in eastern Zhejiang province determined that all the patients had been exposed to poultry, either through their occupation or through visiting so-called wet poultry markets.

The World Health Organization (WHO) had previously said poultry were the likely source of the virus, which has been linked to 23 deaths out of 109 identified cases.
