insofar as the low German rate is explained by more massive screening, it is therefore probably closer to reality. It is rather the high rates which are not very credible since there is more chance of underestimating the number of patients by lack of tests, than the opposite. There are other estimates like those of the Diamond Princess which revolve around the same values ​​when we correct for demography.

In any case, we have to hope that the real rate is around 0,5%, which would limit the number of deaths in France with 40 million infected to around 200 dead, which is already a lot: if the rate is higher, it will go up as much.

You did not look at the link because on March 25, date of the article it was 0.5% because it was a majority of young people who were diagnosed.
Today it's 3.1% https://coronavirus.jhu.edu/data/mortality

We will have the final figure when the R0 is reached, ie 60% of the contaminated population.
mathematicians from Dartmouth College (United States) today suggest, rather than testing only symptomatic people, to test populations randomly. By following an approach similar to that used for carrying out political polls, for example. "If the tests are done correctly, the infection and case fatality rates in the random sample should be very close to the real rates in the general population," the researchers said in a statement on The Conversation.

They take the example of a population of 100 individuals, 60 of which are said to be infected and of which five people are said to have been deplored.

The case fatality rate would then be 8,3%. https://www.futura-sciences.com/sante/a ... ion-80583/

It's been 3 weeks that Germany is no longer at 0,5% ... in short please do not broadcast outdated information ... thank you

Of course, but I was not basing myself on the officially published mortality rates, which depend too much on the number of people tested, but on studies precisely where we systematically tested and found many more asymptomatic infected people than we thought:

https://www.lavoixdunord.fr/739205/arti ... s-que-l-ne

the report (in german): https://www.land.nrw/sites/default/file ... gelt_0.pdf

on the Diamond princess, we are at 14 dead for 700 cases or 2% but with a lot of elderly people (average age of the passengers 69 years, who made 2/3 of the people present)

Certainly also,
If we look at all this in detail, these are not significant "studies". We only noticed the contamination on the Diamond princess when some had been unloaded and contaminated in their country.
at the time of quarantine (February 5), 1 person could infect more than 7 others. The rate of spread was probably also high (estimated to be between 2 and 3 in the general population) due to the cramped and crowded conditions on board. Subsequently, when passengers were locked in their cabins for at least 2 weeks, the average number of people infected with another one fell below 1. Quarantine may have prevented many infections, says Gerardo Chowell, even if it was not perfect https://www.pourlascience.fr/sr/covid-1 ... -19031.php
In all the cases listed in your link, it is thanks to confinement that this low rate was obtained.

A study by the Institut Pasteur .. which seems to confirm the estimate of the fatality rate of 0,5% : Wink:

Interesting, some estimate the R0 at 60% of contaminated, it is rather 70% here
we will be very far from the 70% that we would need to be able to leave confinement without a problem, "he underlines.
If it's pretty sure, we can already do table corner calculations.
6% contaminated, 66% of 67 million French people remain to be contaminated = 44 million * 0.005 = 220000 potential deaths.

After that we must be able to calculate the time necessary to reach these 220000 deaths with "a pseudo - linear slope" at 0.5%, knowing that today there are 20265?

I do not see how this new study which affirms that "theoretically" 6% of the French will be affected on May 11 is encouraging ... : Shock:

This mathematically reduces the death rate ok ... but that's all that is gratifying!

There are so many unknowns and bad news every day ... that most specialists are rather lost!

I'm not one, but I think I understand that a generalized infection greatly increases the risk of mutation! No ?
