With the global outbreak of the new coronavirus, scientists’ awareness of the virus is growing. The evolution and toxicity of the virus is being further revealed. Last week, during a visit to the Pasteur Institute, French President Emmanuel Macron told Macron that they had observed a 1,000-fold increase in the toxicity of the new coronavirus in some samples. This also explains why some patients are more ill.
Some viruses are 1,000 times more toxic than regular viruses.
The toxicity of the virus determines the transmission and infection capacity of pathogenic microorganisms. The findings of researchers at pasteural research have shown that the new coronavirus is so toxic in some patients that it is sent to intensive care. Previously, clinicians believed that the causes of the new coronary severe disease, including the patient’s immune cells are over-excited, causing cytokine storms.
“We were very surprised that a large number of new coronaviruses were found in samples from some patients. Sylvie van der Werf, director of the National Respiratory Virus Reference Center at the Pasteur Institute, explained to Macron.
Van de Wolfe has previously told Macron that some viruses are 1,000 times more toxic than common viruses. “It’s completely different from the flu virus estheves we traditionally see or other respiratory viruses. “The new coronavirus is very different from the coronaviruses of MERS and SARS, which explains why the virus is so contagious, ” she said. “THE INFECTION MORTALITY RATE FOR MERS AND SARS VIRUSES IS MUCH HIGHER THAN THAT OF THE NEW CORONAVIRUS.
The findings differ in their judgment seints with previous Chinese researchers. “For infectious diseases, it has some characteristics, and the virus may decrease as the second, third and fourth generations go down,” Professor Qiu Haibo, a member of the National Health and Health Council’s expert group, told News 1 and 1 on February 25. “
Professor Frederic Adnet, director of the Centre for Emergency Services at L’Hopital Avicenne in Paris, France, said the condition of patients with new coronary pneumonia is usually divided into two stages: the first stage is 5-6 days after the onset of symptoms, the condition is relatively stable and has fever Cold symptoms such as cough, cough, etc.; the second stage is from the 6-7 days, some patients will be rapidly deteriorating, although the number of patients is still a small number, especially in the susceptible population, the situation will be very serious after the occurrence.
First death of a paramedic in France
According to the Pasteur Institute, 20 per cent of new coronasinn pneumonia patients in France currently require hospitalization, of which 5 per cent need to be in intensive care. These patients in intensive care are not only elderly and people with underlying diseases, but also young people without underlying diseases. Jerome Salomon, france’s director-general of health, said half of France’s current population skilled people under the age of 60 use in vitro life support equipment.
On March 22nd Olivier Veran, France’s health minister, announced the first medical staff to die from a new coronary pneumonia infection, without giving further details.
Although there is no data to show whether health care workers are more likely to develop serious illnesses after infection, the experience of Chinese and Italian health care workers is not in the minority. The researchers believe that some patients may be hyper-toxic viruses in the body, infecting health care workers.
Professor Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine, said: “We know that the new coronavirus has a high mortality rate in older patients, but we don’t know why the disease exposes some young front-line health care workers to a huge risk. Professor Holtz speculated that health care providers are in close contact with patients and that if there is a lack of protection, they are vulnerable to infection, and that some patients may be more contagious.
According to the latest report of the French Ministry of Health, as of March 21, the number of confirmed cases of new coronary pneumonia in France increased to 14,459, an increase of 1,847 cases from the previous day, of which the number of deaths increased to 562, an increase of 112 from the previous day. Of the confirmed cases, 6172 cases were hospitalized and 1,525 were seriously ill.
Macron announced on March 19th that it would increase funding by 5 billion euros to support research projects related to the new crown. The Pasteur Institute has signed a phase-first agreement with the Alliance for Innovation in Epidemiological Prevention (CEPI) to support vaccine development, and research on the effectiveness of hydroxychloroquine in new crown therapy is being advanced across France.
