As the death toll from China's bird flu outbreak rose to 22 with news of another victim in eastern Zhejiang Province, the World Health Organization warned the H7N9 virus was one of the most lethal that doctors and medical investigators had faced in recent years.
"This is an unusually dangerous virus for humans," Keiji Fukuda, WHO's assistant director-general for health, security and the environment told a news conference in Beijing Wednesday.
"We think this virus is more easily transmitted from poultry to humans than H5N1," he added, referring to the bird flu outbreak between 2004 and 2007 that claimed 332 lives.
"This is definitely one of the most lethal influenza viruses that we have seen so far."
WHO said H7N9 virus one of the most lethal so far ? That's what I'd like to know too.
This disease sprrads from human to human.
Every year it's the flu that will kill us all..... Boring.
"HLNG!"That's the noise the wolf made when it swallowed Peter. Peter kept writing articles all the way down his gullet.
