[ Students take turns entering the building in an orderly manner and must go through a thermal detector that, if it detects any anomaly, forces the temperature to be taken again individually.

Body temperature control continues throughout the day, as well as constant hand washing before classes, in the dining room and during gymnastics.

The desks are separated by sheets, students must wear masks permanently and keep a distance of one meter between them. A student told the BBC that the most difficult thing is not being able to hug her classmates ... ]

Because you've read The Lancet I give you some numbers:
In France since the beginning of the pandemic to date... for 100 people entering the Hospitals in Marseille , how many deaths: 3.1
For the whole of France but Marseille : 17.8
Then how many people under 74 died in the hospitals in Paris : 22%
In Marseille : 0
In Marseille they only use the hydroychloroquine + azithromycine

@onofno If the data would be this convincing everybody would prescribe it. Anyway, all but a few Dutch hospitals have stopped prescribing it because they see no benefits but, conversely, dangerous side effects.

We threw a socially distanced garden party yesterday and my neighbour the MD on the Intensive Care dept in one of the town's two large hospitals told me he only has three remaining Covid 19 patients and all three will be discharged in the coming week. There have been no new admissions in either of the two hospitals for the last few weeks, and no deaths. This is not representative for the whole country, but only for the North. Elsewhere too, however, numbers are rapidly declining. Whether we can sustain this once regulations have been relaxed remains to be seen.
Right now European countries are talking about how to allow some cross border tourism.

...about Sweden. Here's some data for reference.
View attachment 66013
View attachment 66014

I looked at the Swedish data because Michael Levitt predicted their policy would be a winner and Australia's a "standout loser".
Now I feel much better about my lack of a Nobel Prize:), outside of his field of expertise he doesn't look that sharp.
Sweden has ~ one hundred times the fatality rate from Covid as Australia.
And their disease burden from hospitalisations and sick workers is also, of course, far worse.
The worse Covid outcome was the expected consequence of the lack of restrictions in Sweden.
The hope was that the looser restrictions would have other compensations, better economic outcomes and so on.
But this does not seem to have occurred.
Swedish Bank predicts a 6.8% decline it GDP, very similar to the ~7% decline predicted for Australia (OECD numbers, depends a bit on the details.)
Their economic stimulus handout is ~10% of GDP, essentially identical to Australia (9.9% from memory but the numbers are only forecasts so pointless to quibble about a fraction of a percent).
The unemployment numbers are hard to compare because Australia has a subsidy scheme to keep people on a company payroll rather than officially "unemployed".
But unemployment seems broadly comparable.
So I'd say it's a fairly solid disproof of the "restrictions are pointless or worse" school of belief.

A clearer comparison would be between Sweden and Norway.
I know less about the data for Norway but their death rate is far lower, about one tenth of Sweden.
And the economic hit is comparable, SEB actually predicts Norway's GDP decline will be less than Sweden.

So it looks like a bold but unsuccessful experiment.
It is still early, of course, perhaps there will be payoff later but I suspect the reverse.
With such low case numbers Australia looks better placed to move forward.
Restrictions have started to ease now.
No one at all in hospital with Covid in my territory.
No one in quarantine either, and no new cases for more than 3 weeks now.
Still a few cases in other states but I think no one would swap with Sweden.
Or the US, the UK or almost anywhere else bar New Zealand.

Best wishes
David

Greece also did pretty well. Covid19 arrived quite late, and response was swift. The country will reopen in two weeks for tourism from some European countries, but not from Spain, France, Italy or the UK. The list may change, however.

The problem with numbers on the economy is that these small countries all have a high proportion of GDP imported and exported. The same aplies to the Netherlands, and probably even more so. Going from memory, we export some 60% of what we produce, so if foreign demand tanks, there is little we can do, however good (or bad) our health policies may have been. Germany is our largest market, but the UK is also a big one, and the combined effect of the high Covid19 incidence and their self inflicted Brexit harm will hurt our exports.
At least Germany is in good hands.

Greece simply heeded international and European warnings about it. In addition, like Portugal, it had very much in mind the evolution in northern Italy and Spain.

Now some countries are relaxing, ignoring what is happening in different American countries, a few hours' flight from Europe.

In their day governments, the media and society preferred to look the other way with what was happening in China, now the same with respect to those countries. And then, surely, many African countries.

Without effective treatment or vaccination for now and with confirmed outbreaks in a few countries. The only positive, for now, is that it seems to be less aggressive than before (*), but that may change.

(*) Perhaps the rise in temperatures and, above all, the increased UV radiation have something to do with it. In autumn it will be seen.

The relaxation in some states in the US or the UK does indeed seem premature compared to e.g. Germany or the Netherlands, and more driven by political will than science. However, we shall see. I can only hope my skepticism turns out to be unfounded. Anyway, there is no reason to assume that this will blow over here. There is no travel right now, and Angela Merkel has declined to travel to Washington.

It’s Not Whether You Were Exposed to the Virus. It’s How Much.
https://www.nytimes.com/2020/05/29/health/coronavirus-transmission-dose.html

[ When experts recommend wearing masks, staying at least six feet away from others, washing your hands frequently and avoiding crowded spaces, what they’re really saying is: Try to minimize the amount of virus you encounter.

A few viral particles cannot make you sick — the immune system would vanquish the intruders before they could. But how much virus is needed for an infection to take root? What is the minimum effective dose? .. ]

[ Coughing, sneezing, singing, talking and even heavy breathing can result in the expulsion of thousands of large and small respiratory droplets carrying the virus.

“It’s clear that one doesn’t have to be sick and coughing and sneezing for transmission to occur,” said Dr. Dan Barouch, a viral immunologist at Beth Israel Deaconess Medical Center in Boston.

Larger droplets are heavy and float down quickly — unless there’s a breeze or an air-conditioning blast — and can’t penetrate surgical masks. But droplets less than 5 microns in diameter, called aerosols, can linger in the air for hours.

“They travel further, last longer and have the potential of more spread than the large droplets,” Dr. Barouch said. ]

[ Three factors seem to be particularly important for aerosol transmission: proximity to the infected person, air flow and timing. ]

Italia reabre totalmente el 3 de junio porque el coronavirus se ha debilitado

Italy fully reopens on June 3 because coronavirus has weakened

[ On Friday, the new infected in Lombardy were 382, 70% of the national cases. But the Prime Minister, Giuseppe Conte, considered that it was useless to postpone the total interregional reopening: "The total blockade no longer makes sense, you cannot take prisoners to ten million Lombards for twenty-two thousand infected, which represent 0.2 percent ». Giuseppe Conte has taken into account the urgent need to relaunch the economy and the tourism sector, the most affected, without forgetting the health aspects. Decisive has been the alarm launched this Friday by the Governor of the Bank of Italy, Ignazio Visco: "There is a risk that the Gross Domestic Product (GDP) will fall to 13%, it serves a social pact between the government, companies, unions and institutions ». .. ]
