Totally agree with vampirequeen. It is a bug, the death rate is 1% or less. For most people it will be the equivalent of no more than a winter bug, which they probably get very winter anyway.
The problem is that if it goes free so many people will be ill at the same time that it will disrupt schools offices, and the the NHS.
I am old enough to remember the Asian flu epidemic of 1957 (I think). Most schools had to close down, mine closed for a fortnight, offices, factories. I was too young to be aware of the affect it had on the medical services but I know the mother of one girl in my class died of it, but she already had health problems.
The biggest threat to those with the virus is the pneumonia that some sufferers get. I have had the pneumonia job, which I assume will offer some protection.
The biggest threat to the rest of us is people panicking and running round like headless chickens over stocking with food, most of which will go uneaten and later be thrown out.
