Photo taken on April 13, 2013 shows a screen showing a seven-year-old girl, who was infected with the H7N9 strain of bird flu, receiving medical treatment in the Beijing Ditan Hospital, during a press conference held by the hospital in Beijing, capital of China. This was the first such case in the Chinese capital. The child is in stable condition. Two people who have had close contact with the child have not shown any flu symptoms, and the girl's parents were engaged in live poultry trading in a township of Shunyi District in Beijing's northeastern suburbs.
