Coronavirus
Flattening the curve obviously helps to keep health services from getting overwhelmed but that's subsumed under the primary goal of the suppression strategy (as opposed to the herd immunity strategy), which is to
reduce and eliminate the number of infections thereby reducing and eliminating fatalities. Success in terms of the suppression strategy means less infections and less deaths overall than otherwise would have occurred, and obviously not having your health service overwhelmed aids that, which is why you aim to modulate the degree of suppression to be below that level (the
degree, not the
fact of suppression). Success in terms of the herd immunity strategy, on the other hand, means getting enough people gradually infected so that you reach a point where the disease can't spread because most people are immune (ideally this is also done without overwhelming the health service, the difference being in the former case, you not only flatten the curve but aim to eliminate new infections, whereas in the latter continued infections are required). As I said, this is not hypothetical. If, as you claim, they are both the same thing, then 800 million people will eventually be infected in China (an absurdity if you look at the data) and this will not only happen but will be considered a success as long as their health system isn't overwhelmed. Pure nonsense because, of course, the difference was made clear here and all over the news over a month ago.
The global consensus is suppression and this is why economies were shut down so severely. The result will be less overall deaths than a herd immunity strategy. How many less will depend on when we get a vaccine, what else we do to mitigate spread when we open up and so on.
Posted before. Here posted again. This is what New Zealand is doing to the letter. And it is working.
"Strong coronavirus measures today should only last a few weeks*, there shouldn’t be a big peak of infections afterwards, and it can all be done for a reasonable cost to society,
saving millions of lives along the way."
*Unfortunately, most countries were too late starting for it to be a few weeks. Blame the politicians who delayed.
