So about 3% mortality rate, I'd say that's pretty scary...
From what I read, insensive care was needed for about 20-25% of cases as well. I'm not sure how valid this information is but it's pretty nasty if so.
If you read it, please let us at least know where. Speculating doesn't assist anyone.
Speculating assumes it's not valid information. Not having a reference on hand, having a valid reputable reference, and having and invalid reference are not one in the same so not sure what's being implied.
