I don't know the answer to the combined 'superflu' question if I'm honest. I know the WHO are concerned about both viruses circulating together but I may have misinterpreted that concern (reading too many blogs and stirring panic ).
I agree there has been stirring in some sections of the media. But some of the stirring is necessary. For the first time, our nursery has had better hand hygiene than it has EVER had.
And of course the 'projected potential deaths' are projections. How could they be anything else except after the fact?
Epidemiologists work on past experience until they have actual data. Planning is all about preparing for the worst and hoping for the best.
Don't forget it was the WHO which declared a global pandemic. And then they went 'oops, since this flu seems to be quite mild, perhaps we'd better consider a severity index as well as a spread index in future'.
And the last case of an H1 virus was 1918. In which millions of healthy young people died globally. Some scientists argue that even taking into account the poverty and poor nutrition issues, there were millions of unexpected deaths.
I really really hope you are right that it is all a media stew. In any case, as others have said, death isn't the only or even main worry - it is mass disruption and economic blight because of absenteeism.
I have been trying to find out a bit more about scarlet fever also, as it is what was proposed for my kids when they had SF symptoms. It is a streptoccal (a bacteria) infection as I understand it. Which can also be one of the complications of flu. Whether this strep and this flu I don't know not being a medical type.
