Chinese Scientists Warn Danger of People-to-People Transmission of H7N9

Three “staircases” of the virus genome, which is like a spiral stairs, have been displaced, Li said.
A group of Chinese scientists have warned the danger of H7N9 spreading from people to people as China has confirmed 120 cases of infection of the new strain of bird flu, with 23 fatal. A research group of professors from China’s top universities led by Li Lanjuan, a H7N9 expert, has found that the bird flu virus is increasingly apt to infect mammals, which adds to the risk of people-to-people contraction, according to a Friday’s report by Qianjiang Evening, a newspaper based in southeast China’s Zhejiang Province. Three “staircases” of the virus genome, which is like a spiral stairs, have been displaced, Li said. Stability of the stairs would be sabotaged and people-to-people transmission could become reality if displacement of a fourth should appear, she warned. “Hopefully there won’t be a fourth displaced staircase,” said Li Lanjuan who vowed closer monitoring. An investigation group of the World Health Organization (WHO) Wednesday called for closer international and domestic cooperation as it said experts still have limited knowledge of the virus. The group reiterated that there’s not enough evidence showing the virus being transmitted from people to people. No typical symptoms have been found in poultry carrying the virus, which makes it harder to track, the group said. Taiwan reported its first case of H7N9 infection Tuesday, someone who stayed in Suzhou, Zhejiang Province from March 28th to April 9th. Zhejiang is the most-hit area in the mainland, reporting 45 people infected by H7N9, with 6 of them being killed. The bird flu strain has been spread to 11 provinces including Taiwan.
