VIDEO. Coronavirus: Mortality, patient profiles, vaccines… Where are we in the epidemic?

Inordinate worry, adequate management or communication intended to avoid panic? Difficult to see clearly after weeks of more or less reassuring continuous information on the coronavirus epidemic, which now has its official name: Covid-19. Since the beginning of 2020, the world has been holding its breath to know what the scale, health and economic damage and duration of this new epidemic will be. 20 Minutes takes stock of the situation.

Is the epidemic contained?
Unsurprisingly, China is suffering the most from the epidemic, with 72,300 people infected on Tuesday, many of them in Hubei province. Elsewhere, almost 900 cases have been confirmed in around 30 countries. An encouraging sign announced on Tuesday: in mainland China, the number of new 24-hour contaminations (1,886) is at its lowest since the beginning of the month, and that of additional deaths (98) is down for the fourth consecutive day. The WHO warned on Monday that the spread of the coronavirus remains "impossible to predict."

And for France? During his first press briefing on the coronavirus, the new Minister of Health, Olivier Véran, announced Monday evening that out of the twelve confirmed cases of infection, six people remained hospitalized. This Tuesday, representatives of hospital staff and liberal doctors are received at the ministry to provide an update on the organization in the face of a possible epidemic.

Because if the health authorities try to reassure, this coronavirus surprises more than one. "There are around 2,000 new cases per day, which means that we are not at all at the end of the epidemic, warns Frédéric Tangy, professor at the Pasteur Institute and director of the vaccine innovation laboratory . For now, it is contained in China at the cost of enormous efforts: city and airport closings, canceled events ... But for how long? What surprises this specialist is the duration of the epidemic, but also of the pathology. "It appears that patients die late, sometimes a month after infection, which is new compared to other coronaviruses. "

What is its mortality rate?
The toll of the epidemic rose Tuesday to nearly 1,900 dead in mainland China, and to 5 deaths elsewhere (Philippines, Hong Kong, Japan, Taiwan and France). Citing a study by the China Center for Disease Control and Prevention involving more than 72,000 people, WHO director Tedros Adhanom Ghebreyesus said Monday that more than 80% of patients currently infected suffer from a mild form of disease.

"This coronavirus has exceeded in duration and scope the SARS [severe acute respiratory syndrome, which killed 800 people for 8,000 cases between 2002 and 2003] and the Seas, coming from the Middle East, [449 died for 1,219 cases in 2012 -2013]. It is more contagious, but has a lower lethality - around 2.5% -, when the mortality rate of Sras was around 9% and that of the Sea 30%. But it's still forty times more than the flu… ", says Frédéric Tangy.

What is the patient profile?
According to the same study by the Chinese Center, up to 39 years of age, the mortality rate from Covid-19 remains very low, at 0.2%, then increases gradually with age. Another Chinese study, that of the State Key Laboratory of Respiratory Disease in Guangzhou, identified by Sciences et Avenir, was carried out on 1,099 patients. Infected and critically ill patients often combine this disease with other pathologies: hypertension (in 23% of cases), diabetes (16.2% of cases).
