BEIJING (AP) -- China says two more people have died of a new strain of bird flu, bringing the death toll to nine.
The official Xinhua News Agency also says the number of confirmed cases of human infection had risen by four to 28 by Tuesday evening. The first cases of H7N9 were announced last week. All have been reported in Shanghai and three eastern provinces.
Citing health authorities, Xinhua says there has been no sign of human-to-human transmission. Health officials believe people are contracting the virus through direct contact with infected fowl.
Some cities have suspended sales of live poultry.
