Covid-19 Outbreak of new SARS-like coronavirus (Covid-19)

Of course it will hit all at once. Sure it won't happen all on the same day, but it'll happen way way way faster than if we take social isolation actions to slow it down.

And social isolation won't entirely stop the spread. It will continue to spread, just slower.

Exactly how is social isolation going to make things worse?

You say stuff like "however it will hit pretty much all at once if you have isolation, with limited mixing and slow build of multiple reservoirs( Inoculation sources) and then suddenly do complete mixing of these sources with the population when you release the restrictions".

But that's not an explanation. It's just a restatement of your claim. Why? Why will that happen. What are these reservoirs of infected people and how is it worse because of isolation?

It seems like you're just restating your argument but I'm not seeing any clear reason for specifically why you think that.

Please just think about it. Social isolation leads to clusters of infected individuals, limited mixing means that outside these clusters there are still susceptables because they haven't come into contact yet, release the restrictions with the inevitable rapid mixing and it is like simultaneosly inoculating multiple points on a petri dish there is a rapid immediate growth, with most new infections being temporally associated. if you have ever done fermentation or tissue culture you will get the concept, distribution of the inoculum is key. if you properly distribute a concentrated inoculum by using a waring blender for example the initial growth rate is spectacular and simultanous across the media.
that is the explanation I'm sorry if I have't explained it simplistically enough for you and you still you can't understand the concept, I have tried.

In China some cities did heavy handed isolation others didn't and those that didn't did not have worse outcomes.

There are other approaches, chloroquine is effective against nCOV like SARS perhaps we should prophylactically use chloroquine at the kinds of dosages once used for malaria prophylaxis, or better reserve it for those who are vulnerable and get on with this.

It seems like you're suggesting that social isolation would result in a bunch of people with the virus all reentering the community at the same time. But that's not what I see happening at all.

We don't just quarantine the infected then let them come back while they're still sick.

We isolate everyone. We tell them go stay home unless they gotta go to work for essential services, or need medical attention or similar. This will result in a much slower spread of the virus. Not no spread, less spread.

Then, after say, 6 weeks. We start lifting the isolation. But we keep mass events canceled. Most of the ones who were infected at the time will have either gotten better or died. And so won't be spreading it anymore.

Infections will start to increase again but we will have bought much needed time and the people we treat in that time will hopefully be immune, meaning they won't then use up medical resources when the virus starts spreading again.

I don't see how more people could die because of this. It seems like you're thinking that isolation would mean the virus would spread faster in the isolated. It won't, it'll spread slower. Or you seem to think that those infected and isolated will just stay sick the entire time. But neither is true.

Isolation and social distancing will slow down the spread, that's it. And we need to slow down the spread. There are different options for how to do it, and some of the more aggressive ones have their own economic problems. But the point is we need to wherever it's at all possible reduce how the amount of human interaction.

your simplistic view works if there was not significant asymptomatic and mild infection. Isolated people are not completely isolated they will transmit it inside their clique or cohort, if your isolation is 6 weeks then that is only 3 passages. There will then be mixing of cohorts once you lift the restrictions and we are off to the races again. maybe you don't see this as a flaw in your great plan, I do. Isolation can hold back the force of infection only so long as it continues, but sooner or later you have to lift isolation and you still have cases and a large number of susceptables. Plus you have caused a global collapse. good job there.

As it stands delaying strategies will push peak infections towards the middle or late northern hemisphere summer, in AUS that would mean it would hit right in the middle of flu season. AUS is better off getting the peak sooner before the winter flu season otherwise you really are going to have problems.
all the while patients die unneccesarily from other conditions because of delayed treatment to preserve capacity.

you don't know who is infected or not so you do not know when to lift the lid off the isolation pressure cooker.

off topic rant, who is this we? you keep saying we. I am not part of your group, there is no we as far as I am concerned. You seem quite happy to hand control of your destiny to a bunch of incompetents, good for you.

We is us, humanity.

And yeah, I'd much rather listen to the medical experts and disease experts than you. You're right about that.
 
saves you having to think for yourself I guess.

I've already thought for myself. I agree with the experts. For all the reasons I've already given.

I gave you a chance to convince me my opinion is wrong. It didn't convince me.

And if I had to put my faith in someone who I thought knew better than I did. It'd be the general consensus of health experts. Not you.

good for you. good luck
 
What annoys me is how obvious it is that politicians aren't doing enough to avoid catching it to start with. Which means they're interacting with many people. Which means they could be infecting many more before they become symptomatic.

They keep saying shit like that they will prevent spreading it by doing their interactions over internet link.. Why weren't they doing that already?

Sweet isolation is always the answer. Even before this virus, I wanted to stay away from humans. This is a great excuse.

cmon you are just wanting to see flamboyant symbolic but ineffectual responses. The pols are as bad as anyone else.
You have shown you are very keen on symbolic extreme isolation, otherwise known as extreme can kicking responses.

Like it or not for equilibrium there needs to be roughly 40% non susceptible. 40% is 40%, area under the curve is the same whether it is flat or steep. Heavy handed isolation and movement restriction measures do not allow this to occur without repeated spikes, the biggest spike one incubation period after releasing restrictions when capability has already degraded. Even a relatively low force of infection will take out all the ICU availability. which is what? perhaps in total 10 per 100 000 population, 0.01%. It is not a good idea to take out all ICU capacity for months on end, the longer it goes on the more staff get sick the more the supply chains fall apart and so on and so the capabilities degrade further. Heavy handed lock down early in the exponential phase just stores infection pressure, but it has other serious consequences.

This is not SARS, there is cryptic and asymptomatic transmission so the SARS strategies do not work. Because you have reservoirs.

if you think that severe heavy handed lock down is the only expert backed opinion you would be very wrong, there is simply no evidence that banning football games, concerts or closing schools is in any way effective, and curfew is also ineffective over the longer term. Mainly because you have to end it at some point, when? 6 months a year? when?

If you want to educate yourself I suggest you read what Patrick Vallance (UK science advisor, my one time boss who at the time was one of the few fighting for new antibiotic research so one of the good guys in my book) or Michael Osterholm (independent public health expert stateside) have to say on the subject, My position is probably right, you are probably wrong, but actually it doesn't matter because you are not making my strategic decisions.

I don't know why I bother trying to communicate this, because you have shown an inability to grasp some basic biological concepts or I haven't explained them clearly enough, but I figure it is either me or you, either I am obviously failing to communicate the concepts clearly or you are unable to grasp the concepts or are not open minded enough to visualize the possible scenarios going backwards from the end game, which is endemic seasonal disease which attenuates over time.

I don't need you to agree with me, per se, but I am wondering if the failing is I am not speaking a suitable language??

I can post the numbers and calculations that lead to some troubling conclusions about the required duration of capacity preserving strategies but I think people will take them the wrong way and I don't want to be irresponsible. if you think 2 week lock downs will work you are dreaming, same goes for 2 month lock downs.

so last try.. good luck

Do you think there's an ulterior motive to the disproportionate response by the global community?
good question.
I think that the politicians are trying to be seen to be doing something because the media has whipped up something akin to hysteria.
The governments then will take advantage of the opportunity a crisis presents to increase power, control or wealth.

The more trusting (naive) among the population will applaud.

We saw it with 9-11 We saw it with H1N1 and then with the measles bullshit last year.
 
I think it's possible the big whales in the stock markets are trying to use this event to cause panic in investors to buy low, sell high, but then again, let's not discount the natural tendency of investors to panic.

what has been missed in the coronavirus noise is that aggressive dumping of crude oil, driving the prices through the floor, which was instigated by the end of OPEC+ is really doing the damage. At the current price there is not one shale producer that can survive more than a few months, the Shale oil complex is a big deal in for the USA. If the Fed bail out the shale producers they risk collapsing faith in US treasuries. The market was looking sketchy back late last year and a lot of people started selling into the top.
So with oil simultaneously there is demand and supply side pushing the same way, there then is significant liquidity issues, as the market moves margin calls are hitting which is forcing liquidation of any asset that is in the money. It is very much a classic example of the end of a cycle.

A recession is baked in now.
 
So you remember Swine Flu in 09

At that time, the WHO changed it definition of 'pandemic', removing the statement that "an enormous amount of people have contracted the illness or died" from its existing definition and replacing it by stating simply that there has to be a virus, spreading beyond borders and to which people have no immunity.
