Already in that eastern region of China, nine cases of this strain have been officially confirmed. But unofficially, there have been reports that the situation could be much worse.
On Tuesday (April 2) Chinese author Ge Hongbing posted this message on his Weibo microblog account. He said that the contagious diseases office of the People’s Liberation Army 301 Hospital have issued an emergency notice. The missive said that three people have died in Shanghai from the H7N9, and that almost 100 have been infected.
Hong Kong’s Wenweipo newspaper reported on Tuesday that a doctor at the hospital where the two patients died says there has been a sudden increase in pneumonia cases. The two fatal cases in Shanghai both developed pneumonia, a symptom of the H7N9 virus.
