Do you agree that governments force a variety of "measures" to block spreading of corona?
If you don't, then I recommend to read news from the last X months, and/or to take a look inside cities.
If yes, do you further agree then if those measures succeed in blocking spreading of corona, shouldn't they also succeed in blocking spreading of influenza? And do that even better, due to influenza being called less dangerous and not been "lockdowned" like corona now, difference being caused by influenza immunity bigger than corona immunity, so IF there would be an influenza epidemy, then that would imply that the measures so called against corona didn't work against influenza, let alone against corona, in other words: unneeded/useless.
And third: that "protection" you talk about, has its own cost, an element that you seem to ignore.
To illustrate its major importance: imagine giving blocking corona top priority over everything.
Fine, everybody, to the last man and woman in the world, in quarantine, all companies cease production, economy basically looking like after a neutron bomb has been dropped, then corona virus spreading will surely be stopped.
The gain: nobody will die from corona.
The cost: everybody died from starvation.
Get it?
Last part first, I don't want it!!
That includes flu, by whatever prefix you use.
2001, I'm in an area where the only means of transport in the area was in a motor vehicle. Short distances on foot allowed, but I'd to stick to the highway. Lockdown at times that make this time seem like nothing. Large areas that couldn't be used. They came down heavy on you if you broke the rules, unlike now. Last confirmed death from foot and mouth, in the UK, was in 1966.
With flu, there's already a yearly injection/jab. This time, C-19/CV-19/Coronavirus, there isn't. It's an unknown, just like 100 years ago, only science has moved on. Not all for the better in my own opinion, but they can give you treatment that would have saved many 100 years ago. We, as individuals, however have become complacent over the years. Simple hygiene measures not followed. "It'll never happen to me" is commonplace.
If folk are made to remain apart, social distancing, to try and avoid the spread of one, would you not expect to see a drop in the other, similar virus related illness.
From advice on dealing with flu
"Cover your nose and mouth with your arm (not hands) while coughing or sneezing; wash your hands frequently to avoid the spread of germs.
Use paper tissues that you can toss after use instead of cloth handkerchiefs to avoid giving the virus to others."
Seems like good advice to me, and I've never had flu. Bad colds, but never flu.
It was expected to be over and done with in no time. This being the 21st century and all that, but the human body, for all its strengths has many weaknesses. Had the long term view been taken at the start, and implemented, then you may well have seen more people planning ahead. We live in a "Me Society" which doesn't allow too much of thinking about others. Maybe now we're paying the price for that, we can't adapt to meet the current situation.
Maybe it's time to stop thinking of this situation only affecting others, who are preventing you from doing what you want.
