Shanghai, Apr 7 (EFE).- Twenty people have now been confirmed infected in the past week with the H7N9 strain of bird flu in eastern China, of whom six have died, with the two latest cases in the metropolis of Shanghai, the region most affected by the outbreak of the disease, health officials said Sunday.
A 67-year-old Shanghai resident and a 59-year-old resident of the nearby province of Anhui are the latest people infected with the virus and diagnosed with pneumonia after exhibiting flu symptoms, the Chinese Health Commission said.
Shanghai, China's most populous city with 24 million residents, registered two flu cases on Saturday.
A week ago, state media reported that two men died from the H7N9 strain of bird flu in Shanghai.
This strain had not infected humans previously, the official Xinhua news agency reported, citing China's National Health and Family Planning Commission.
The patients all initially suffered from fevers and coughing, but they all developed severe pneumonia later.
