Since the first cases of the deadly H7N9 bird flu strain appeared in Shanghai earlier this month, Chinese health officials told the world not to panic because they couldn't find solid evidence of human-to-human transmission in any of what have grown into 82 reported infections. They maintained that until, well, guess what China's health experts are saying for the first time today? "Human-to-human transmission, in theory, is possible, but is highly sporadic," Feng Zijian, director of the health emergency center of the Chinese Center for Disease Control and Prevention, toldreporters in China on Thursday. "Further investigations are still under way to figure out whether the family cluster involved human-to-human transmission," Feng added.
The "family cluster" he's talking about is a case in which two sons may have contracted bird flu from their father, an 87-year-old man thought to be the first reported case of China's H7N9 virus,according to China Daily. Perhaps even more worrisome: The World Health Organization said Wednesday that there are other humans, aside from the two brothers being investigated, who appear to have contracted the deadly virus without any contact with poultry. (Even though it's called bird flu, that's how the Contagion thing was supposed to work with the spread of H729.) "It might be because of dust at the wet markets, it could be another animal source beside poultry, it could also be human-to-human transmission," WHO spokesman Gregory Hartl told Reuters. So, to be clear, officials aren't quite sure how people who aren't handling poultry are getting this strain of bird flu. And, to be sure, that's pretty scary.
