Two Shanghai men have died from H7N9 bird flu in the first known human deaths.
Chinese authorities said on Sunday that it wasn't clear how they were infected, but that there was no evidence of human-to-human transmission.
A woman in the nearby province of Anhui, also contracted the H7N9 strain of bird flu and was in critical condition, China's National Health and Family Planning Commission said.
