1) France is following an approach similar to Italy rather than Asian countries that have been more successful through widespread testing, contact tracing, quarantines, and isolation. 2) The number of new confirmed cases in France continues to rise with over 3,900 new cases reported. The health system is still able to absorb patients but may be overwhelmed for a long period of time like in Italy. 3) Globally there are over 63,000 new cases reported with the equivalent of 15 large outbreaks like Wuhan currently occurring worldwide, particularly in Europe, the US, and Spain. The US is on track to surpass China's total case count within days.

1. Lack of means, France moves towards
forced collective immunity
A. France and Europe seen from Asia - We are at
war, and the Asian examples show us the way
forward!
This section is produced with discussions with Dr Bachir Athmani in Paris and Mathieu
Bouquet in China.
“Put down the masks” and stop half-measures: we must adopt the recipes that work!

2. 1. Wearing a mask (if possible generalized!)
This tactic has proven itself: there are countries that use it and that win ... and others!
If our industry is not able to supply this type of product (which shows our extreme
dependence on China, already illustrated by the cost hunt in the pharmaceutical industry),
we must turn to l factory in the world, which currently produces 100 million masks ... per day!
(against a capacity of less than 10 million per ... week in France). Even if China produces of
course with varying levels of quality.
The masks (FFP2, surgical) must initially be reserved for healthcare professionals (around 2
million units per day) as well as for people in repeated contact with the public (Ehpad, police,
cashiers, etc.).
2. Massive screening
This is the key to the Korean strategy to detect cases and isolate them immediately.
Note the figure of 500,000 tests per week in Germany, compared with less than 50,000 per
week for France.

3. The development of this type of reagent by our laboratories (human or even veterinary
biology) is not, according to some specialists, a very complex element. Chinese, Koreans
and even Vietnamese did it urgently, without having a month of preparation before the arrival
of the epidemic on their territory.
3. Massive disinfection of public spaces
This is the case in China and South Korea in particular. Note the use of spray robots in these
two countries.
4. Identification and management of positive cases and contact
cases
This is an essential point.
In China and most Asian countries, a ​Covid patient is immediately isolated in hospital or
in a quarantine center​. This measure was initiated in Hubei, after the authorities became
aware of the very large number of intra-family contaminations (some families have been
decimated).
In France, a patient with little symptoms returns to his family, which creates a great risk of
family contamination.
Likewise, in China if a ​contact person​ is identified, they are ​under quarantine​. Quarantine
is now done in dedicated centers, and much more rarely at home.
If a suspect case is identified, isolation of the entire residence (China, Vietnam, etc.) until the
doubt is resolved. If the case is positive, the patient is isolated in hospital, and the
confinement of the residence is maintained for 14 days, with temperature monitoring and
possibly biological tests.
5. War effort: DIY or deployment in order?
Some hairy people spent months in the trenches. We have to spend 4 weeks (+/- 2) at
home.
All industry​ that can be mobilized must ​provide solutions​ for the development of the basic
elements of the fight against the virus (protective gear, care materials, etc.).
The lack of beds in public hospitals (eg in Paris: the 1,000 intensive care beds are occupied
or about to be occupied) can be compensated by the participation of the private sector.

4. Reduction of summer holidays ​for schoolchildren, university students and their parents
(solution preferred by China and Vietnam, where classes have not yet resumed).
Our health system must reposition itself in an emergency, when it is above all risk-oriented:
● acute​ (“White Plan”): mechanical (trauma) or chemical (see recently in the West) or
thermal or even nuclear type
● localized ​(type of attack or major accident) and not throughout the country.
● non-progressive, ​whereas we have to face an epidemic period of around 2 months
days (Wuhan case) with strict containment measures.
This may explain the difficulties encountered by our managers in adapting existing means.
B. France - We are rather following an Italian
trajectory - D11 containment
1. Incidence: +3,922 new confirmed cases (2,933 yesterday)
We remain in the epidemic growth phase, the number of new cases does not seem stable
over the last 4 days.
Note that general practitioners and the 15th have identified more than 40,000 positive cases
since the start of the epidemic, without confirmation by biological tests.
2. Prevalence: 22.5k in observation (20k yesterday)
On this basis alone, ​the doubling time seems to be getting longer (more than 6 days,
compared to 5 yesterday). But the figure of 22,500 does not take into account the
biologically unconfirmed cases mentioned in the previous paragraph.
If France continues to follow the Italian model, the peak could end around mid-April.
3. Trend (comparison with Italy)
To date, France's trajectory remains relatively close to that of Italy, with all the necessary
precautions for this comparison, in particular with regard to the testing strategy adopted by
each country.

5. 4. Health system: analysis of current capacities and flows
4.1. Figures
Deaths: ​1,696, or 6% of cases identified by biological tests (but much lower if we took into
account all people carrying the virus in France)
Severe cases (resuscitation): ​3,375, or 14% of cases identified biologically
4.2. Testimony of a colleague in the Grand Est to the emergency
“I have never had this experience: we usually have 150 visits to the emergency room and at
most we intubate once a day. Today, we have received only 70 patients but we had to
intubate 10 ".
4.3. Our system is still capable of absorbing the wave ...

6. ... but probably more for a very long time. While Italy has already seen its capacities
overwhelmed by the epidemic.
Graph: proportion of severe cases among identified cases
Graphiques : comparaison par pays des cas graves et décès
Note the dynamics of mortality rates (an indicator that is doubtful but its dynamic is a good
indicator) on the rise in France, and which only reflects the difficulties encountered more and
more frequently by carers, in a similar way to what is happening in Spain.

7. NB: precautions to take on mortality figures
In France, the mortality figures provided are probably largely underestimated compared to
reality, since only the figures for hospital mortality are included and consequently they do not
include figures outside the hospital (Ehpad, deaths without biological tests carried out, etc. .).
5. Territorial distribution
NB: the figures for March 26 in the evening were not communicated by region, the map and
the table below show the data available on March 25 in the evening.

9. 5.2. Evolution by region
C. World impact: an exponential dynamic
Thanks to Stéphane, a companion from the start, for his participation.
1. Incidence: 63k new cases diagnosed (46k yesterday, 44k
the day before)
2. Global geographic vision
There are currently the equivalent of 15 Wuhan type homes around the world, including ten
exploded in Europe and which can be joined!

10. The United States and Spain remain in an exponential phase.
3. Continent / country geographic analysis
3.1. Par continent

11. 3.2. By country
There is a high risk of health catastrophe in the United States, where the best technology will
not be able to cope with a massive influx of patients at risk, in particular due to
co-morbidities. Obesity, with its pathological consequences, affects more than a third of
American adults.
Table: evolution by country

13. D. Prevalence worldwide - In a few days, the
United States reaches a number of cumulative
cases greater than that of China in 2 months!
The doubling time in the United States is currently 3 days.
1. Time vision (chronological)
At the current rate, doubling of cases worldwide every 5 days (stable).
Figures to be taken with caution given the disparity of testing strategies: the epidemic can
spread without it being reflected in the official figures, if the patients are not subject to
biological screening and a count official.
2. Spatial vision
Geographical location of countries with more than 10,000 active cases (top 8):
● USA 82k
● Italy 62k
● Spain 46k
● Germany 38k

14. ● France 22.5k
● Iran 16.7k
● Switzerland 11.5k (high density of imported cases)
● United Kingdom 11k

Keep in mind the “3M reflex” (Hands-Masks-Meter) to protect
yourself… but above all to protect the most vulnerable.
