I also want to add to this and what others have said in relation to your belief this is a rational fear.
Yes, it is rational to have concern for illness or accident but it is a healthy concern that does not dictate your life and have to posting in places like this.
Think of another scenario and how your reaction would apply to it:
You fear being run over. Do you take the usual precautions e.g. look both ways? Or do you avoid roads, change direction away from oncoming vehicles, keep checking to see if there are cars coming near to you, feel constantly anxious due it, etc?
Can you see the difference between normal and abnormal response there? So, forget about rational/irrational illness and consider we are saying it is your reactions that are irrational.
Now consider your fear of flu again. Who is most likely going to need to take precautions? Most likely those with health vulnerabilities. The NHS give all such people a free flu jab each year to help. But there are always those rare cases of completely healthy people dying just as there are people who suffer things like sepsis from a common ailment millions of us get each year. You can't counter this because sometimes it's just bad luck anymore than you can stop yourself being killed by a drunk driver mounting the pavement killing you (and this happens too).
And this is another point AMOC made here, it is irrational to fear the flu to such levels when many HAers wouldn't think twice about getting in a car or going out for a night in a town they could be assaulted in or one of many other much greater fears. That's because of your blinkers. It's your thinking that needs correcting and your reactions. It's the same for all of us no matter what our triggers.
Apologies if anyone has already worked through this, I've skimmed.

Erin, our media go wild with stories like this. It comes to something when we have an international anxiety forum where so many Americans have heard of The Daily Mail. How many US newspapers could most Brits identify?
The Aussies on here will tell you the "Aussie flu" is just "flu" to them and ask what all the fuss is about. They have said their media don't bother with it much. And there is the difference.
It's about scaremongering media click bait. And these outlets will emphasise the worst and not mention what you have just said.
We have to be careful due to the motives of the media in question. It may not be that the situation is any different to years before but this is their corporate strategy and reflective of the lack of industry control we have.
I'm sure you've seen Piers Morgan on your TV? He used to be an editor and left for the US after he was found to have completely fabricated a piece showing British soldiers torturing POW's. It was BS, a media stunt. It was picked up because they didn't even get the correct uniforms for the unit they were trying to set up. He's a good reflection of people like The Daily Mail.
