HEFEI - Health authorities in east China's Anhui Province on Saturday reported a new case of human H7N9 bird flu virus infection.

The provincial health bureau announced in a notice that the patient, a teenage girl, was diagnosed in a hospital in Huaining County, Anqing City on Friday. She is in stable condition.

Anhui, along with Zhejiang and Guangdong provinces, are the worst-hit regions for the deadly bird flu. Anhui reported one death from the virus on Monday, triggering concerns about more human H7N9 cases in the country in the near future.

There have been more than 120 human H7N9 cases reported in China so far this year, and at least 32 deaths, according to the health ministry's official tally earlier this week.
