Am I missing something?
If normal seasonal flu kills 8000 people in the uk and this covid is not much worse why are we taking such huge measures to control it?
because it is 10 times more potent than the average flu and very serious for 15% of cases

Do a few quick back of the envelope calculations;
Currently UK gov are suggesting "Herd Immunity" if 60% of the population get infected, though that's a figure widely disputed by a number of other experts, who suggest a minimum of 70-80% and some say even higher.
Obviously there's no way of knowing currently if that percentage of the population are likely to get infected, so I'm not trying to be over-dramatic here, and just providing a possible illustration, which I seriously hope is wrong, but why even publicise this number as part of the strategy unless it has relavence?
Taking best case scenario on the 60% estimate/requirement with a UK population of 66 million approx.
60% of 66 million comes out at 39,600,000 infections.
Death rate is estimated at 1-2%, so again, taking best case, that leaves 396,000 predicted deaths, in order to achieve "Herd Immunity".
It sounds like a potentially dangerous strategy if it all goes per shaped.
From Italy, it seems that, of the small percentage who do require Critical Care & ICU intervention, of those who are on ventilators and receiving full support, there is about a 40% death rate for over 60s ( I assume that is all over 60s, so includes 70s, 80s etc)
Italy has about twice as many high dependency/ICU beds as us, and I think ours are already 80% occupied.
I'll stand to be corrected, but I think we have a little over 4 high dependency beds + 2 ICU beds per capita.
Italy has sent some military personnel into medical ventilator factories, to assist boosting production, and China has sent a large aircraft full of medics an 1000 extra ventilators to Italy, along with other medical supplies.
Some estimates suggest we are a couple of weeks behind Italy, as regards infection rates, though clearly I don't know the accuracy of that.
Here even hand sanitiser is virtually unavailable, Gov is woeful, and folks are stockpiling toilet rolls.
Without straying into politics on an engineering forum, we have no idea how many of the population are currently infected, as the advice at the moment is;
"You do not need to contact 111 to tell them you're staying at home.
Testing for coronavirus is not needed if you're staying at home"
So essentially, no-one knows who's staying at home, and of those who are, no-one knows how many are infected.
I'd best leave it there before I get grumpy and stray into politics
