They should tell us how many people are in hospital awaiting lab confirmation. The virus has been making the run arounds since Feb in humans. Without a doubt the number of possible cases is higher. The number of unexplained deaths to flu is probably also higher. I think we should know these numbers.

I was told on Feb 5 by a Shanghai hospital of a serious deadly virus going around. I have reason to believe this is H7N9 now.
