why the pangolin could be at the origin of the virus?

CORONAVIRUSES. Friday, February 7, Chinese scientists believe they have finally found the origin of the coronavirus. It is said to have been transmitted to humans by the pangolin, a small mammal with scales highly coveted by poachers.

The essential

  • Friday, February 7, the balance sheet of patients with coronavirus in France remains stable with six cases. Agnès Buzyn, the Minister of Health, said that some of them will leave the hospital “the next few days”.
  • The minister also revealed that 38 expatriates will be back on French soil Sunday, February 9. No positive coronavirus case has been identified among French expatriates in quarantine in Carry-le-Rouet (Bouches-du-Rhône).
  • In China, the emotion is intense after the death of the Chinese whistleblower doctor who died on Thursday, February 6. He had announced very early the dangers of the epidemic. Tributes are multiplying.
  • According to some Chinese scientists, the pangolin, a small flaking mammal, has transmitted the coronavirus to humans. This is the hypothesis put forward by research by researchers from the Southern China University of Agriculture.

Philip and Gay are among 3700 passengers stranded aboard the “Diamond Princess”, the quarantined boat off Japan. They are trying to challenge the American government but also the Japanese authorities. “The Japanese government refuses to let us go. So we would like to be the key that allows us to leave on our own. But also so that the American government comes to pick up all the Americans. They do it from Wuhan in China. They know how to do it. The only obstacle seems to be the Japanese authorities, “they said.

The story is unusual. Joseph Yew and Kang Ting, a couple residing in Singapore, got married … by videoconference.

Many sectors of the economy are affected by the coronavirus. Ouest-France currently reports that large luxury houses are trying to put a figure on the cost of the coronavirus epidemic in China. Many shops and shopping centers had to close for security reasons, “downgrading their financial prospects”. A sum that will necessarily be significant since Chinese buyers represent more than a third of spending on luxury goods worldwide.

17:03 – A climate of mistrust vis-à-vis the Chinese authorities

In 2003, during the SARS epidemic, also caused by a coronavirus, Beijing’s behavior was controversial. Indeed, the authorities had tried to hide the reality by hiding the sick. 17 years later, when the 2019-nCoV coronavirus is raging in China and abroad, the atmosphere is at mistrust vis-à-vis the Chinese government. Le Figaro reports that President Xi Jinping has called for increased censorship. Nevertheless, the WHO hailed “the response and the transparency of the country in its treatment of the epidemic” current. However, Liberation specifies that the official count of the victims is not beyond reproach, “far from it”. Many people with similar symptoms have not been tested, and therefore have not joined official statistics.

16:37 – The “real” figures of the coronavirus revealed by mistake?

Since February 1, unverifiable screenshots have been circulating on the Internet, showing a counter of virus victims in China. The Liberation CheckNews service took an interest in the images, answering the following question: did the Chinese company Tencent accidentally reveal the “real” figures of the coronavirus? Indeed, the counter was published on Tencent News, the news site of the Chinese digital giant Tencent, and shows the number of contaminations, deaths, suspicions and cures, almost in real time. According to Internet users, the counter would have displayed figures at least twice almost 100 times (nearly 25,000 dead). Voluntary data leak organized by whistleblowers, or simple computer bug? Contacted by CheckNews, Tencent said the images were fake.

The news of the coronavirus is marked in recent hours by the death of Li Wenliang. This man was a 34-year-old ophthalmic doctor and he is now one of the victims of the coronavirus, but his death made the headlines because he was one of the first to launch the alert in late December on the dangers the forthcoming epidemic of viral pneumonia. At the time, the Chinese authorities even reprimanded him for this, accusing him of “spreading rumors online” and “seriously disrupting social order”. Li Wenliang was then forced to sign a declaration in which he unwittingly admitted a “crime”.

But little by little, in front of the growing number of dead and contaminated with coronavirus, the Chinese authorities carried out a back co-pedaling in due form, making the young ophthalmologist go from threat to hero. Falling ill in mid-January while treating a patient, he announced that he had coronavirus on February 1. And even if he is not part of the typical profile of people succumbing to the coronavirus, who are essentially already fragile and / or elderly, Li Wenliang died this Thursday, February 6 in the evening, causing anger and emotion in China.

The virus was born in Wuhan, China, in a market, and was transmitted to humans by an animal. Currently, the preferred track of the origin of the coronavirus is that of the bats sold on this market. This hypothesis is based on a genetic comparison of the complete DNA of the 2019-nCoV virus: it is 96% identical to a viral strain of bats, which had already been the source of the Sars coronavirus. in 2002. But other avenues, such as that suspecting transmission from snakes, are being considered.

Symptoms of 2019-nCoV coronavirus are similar to those of influenza or pneumonia. Patients have fever, severe respiratory problems and cough.

The human-to-human transmission of coronavirus 2019-nCoV is now proven. The airway seems to be privileged in the transmission of the virus, via the droplets of saliva propelled in case of cough mainly. Contact with “surfaces freshly contaminated with these secretions” can also lead to infection. The coronavirus survives very poorly outside a short-term host, in the air or on objects.

Jean-Christophe Lucet, head of the bacteriological service of Bichat hospital, believes that “wearing a mask in town, it has absolutely no interest today”, adding: “The risk of meeting a patient carrying the coronavirus is very low.” Masks are useful when worn by a sick person to avoid infecting other people. For more information, see our article on masks.

There is currently no specific drug for the coronavirus and the treatment remains symptomatic. Beware of false information and rumors circulating on the internet, that cocaine or the consumption of hot whiskey and honey could be treatments against coronavirus. Thai teams have announced that they have treated patients with a cocktail combining Arbidol, a drug used in China and Russia to treat the flu, combined with the drug Darunavir, used to treat patients with AIDS. However, these results need to be verified by other studies.

China, Australia, and the French teams of the Institut Pasteur have managed to isolate and culture strains of the 2019-nCov coronavirus. Now, researchers at the Institut Pasteur can begin to test “known antiviral molecules” then “propose a vaccine candidate” and hope to develop a vaccine by the end of summer 2021.

The Chinese National Health Commission has released statistics regarding victims of the coronavirus. Over 80% of those who died were over the age of 60, and over 75% of those who died from the coronavirus had more than one other health problem, such as diabetes. The virus can also be contracted by children, but the symptoms are less severe.

According to Chinese statistics, in Hubei, at the heart of the epidemic, the death rate is 3.1%, but elsewhere it is only 0.16%. These results are however provisional and are likely to change depending on the spread of the epidemic, and the mortality rate which is still difficult to estimate due to the novelty of the virus. Comparisons with other epidemics must also be very careful.

No study yet has proven that dogs and cats can be infected with the coronavirus, according to the WHO. Questioned by LCI, the infectious researcher Olivier Terrier, from the CNRS declares that “the risk on French soil, and more generally in Europe, is almost zero. For there to be contamination via an animal source, it would already be necessary that the animals are carriers of the coronavirus “. “The risk is close to zero,” he said, adding that the inter-species genetic barrier is difficult to cross for a virus and protects our pets.
