Two patients from east China's Anhui and Jiangsu provinces who were confirmed as H7N9 cases days ago died of the avian influenza, China's News Agency (Xinhua) reported.
This has brought the total number of deaths caused by the H7N9 bird flu in the country to nine, the National Health and Family Planning Commission announced in a daily update on H7N9 cases across China. The agency also said that, during the 25-hour period, China has confirmed four new cases of H7N9 avian influenza.
China officially confirmed the occurrence of human infection with the H7N9 virus late last month. So far, China has reported a total of 28 H7N9 cases, including nine which ended in fatalities.
