💊 Coronavirus – Everything you need to know about the epidemic


Symptoms, mortality rate, health measures, progress in medical research … find here a maximum of elements of response concerning the epidemic of Chinese coronavirus COVID-19 (ex 2019-nCoV), as it evolves and the latest information is known.

Is the virus contagious? How to protect yourself from it? Like all epidemics of an unknown virus, the current epidemic of Wuhan coronavirus or COVID-19 (ex “2019-nCoV”), a virus similar to that of SARS, raises many concerns and questions.

How many people have been affected by this coronavirus?

The epidemic of the COVID-19 virus (formerly 2019-nCoV) or Wuhan coronavirus is said to have started in early December 2019, in the city of Wuhan, China. The first infected people are said to have visited the town’s fish market, which sells a wide variety of foods and wild animals. On February 11, the World Health Organization officially renamed this COVID-19 virus to “Coronavirus Disease 2019”. The disease it causes has also been named: SARS-CoV-2 (echoing the first epidemic of SARS-CoV in the 2000s).

The alert was said to have been initially launched by doctors in Wuhan a few days before initial action was taken. The latter was then arrested by the authorities for “spreading rumors”. One of them – Li Weilang – is believed to have died from a coronavirus infection. An investigation has been opened into the matter by the Chinese authorities.

What are the causes and origins of the virus?

Therefore, the virus before transmitting to humans must have been of animal origin. The most likely hypothesis is that of the horseshoe bat (Rhinolophus sp.), A proven vector of the SARS coronavirus (severe acute respiratory syndrome), very close to COVID-19. Chinese researchers have discovered the identity of the virus’s intermediate host or “reservoir”: the animal transmitted the virus to humans after being infected with the vector species.

According to their genomic analyses, it is a species of pangolin, the most poached animal in the world and one of the most endangered, possibly sold at the Wuhan market. As a result of this discovery (still to be validated by the scientific world), the Chinese government has banned the sale or transport of wild animals until further notice.

The evolution of the epidemic, how many people infected and dead?

Since then, the current toll [as of Tuesday 18/02/2020] officially amounts to more than 1,800 victims, including one in Hong Kong, the Philippines, Japan, Taiwan and France, and more than 73 000 people known to be infected worldwide.

The first case of contamination was noted Friday, February 14 on the African continent, in Egypt. The epidemic could be reached its peak at the end of February. As a recent Chinese study, only a third of those infected were physically passed through Wuhan.

In China, the number of dead and sick people officially exceeded that caused by the 2002-2003 SARS epidemic. From the report of Hong Kong researchers, the actual number may be significantly higher when counting infected people who are still symptom-free.

12 of the people affected by the coronavirus are in France. Of the six British citizens infected at the Les Contamines-Montjoie ski resort, only four are still hospitalized. They were allegedly infected by a man from Singapore and then returned to the United Kingdom. A twelfth, an octogenarian Chinese tourist, died this weekend.

People who were infected while not traveling to China have been confirmed in France, Thailand, the United States, Germany, Japan, and Vietnam. These individuals have been in contact with people from China or directly from Wuhan. A person, in a French repatriation flight in progress, would present symptoms of viral pneumonia. It will be quarantined upon arrival.

Several dozen people are said to have recovered from the infection in China. Several hundred people have recovered from the infection since the start of the epidemic in China. Two passengers on a Hong Kong-Italy flight are said to be sick with the virus and may have infected several people. The number of people who have recovered from the infection has now largely surpassed the number of deaths since the start of the epidemic.

What are the health effects of this coronavirus? How is the infection declared?

COVID-19 is a virus very similar to the coronavirus responsible for the 2002-2003 SARS epidemic. It causes a high fever, a severe cough as well as great fatigue. According to scientific experts from The Lancet, dyspnea, or respiratory distress, seems to be a characteristic complication in a large part of the patients. This disease is spread through close contact with an infected person or through their postlets when coughing or sneezing.

According to a new Chinese study, some infected patients may have traces of the virus in their digestive tract but also in saliva and urine. In addition, according to these researchers, the incubation period could actually last longer: 24 days rather than fourteen. According to current Chinese data, the mortality rate for COVID-19 is 3% – which is lower than the 10% rate for SARS coronavirus and about 30% for that of MERS (Middle East respiratory syndrome), appeared in 2012. The speed of its spread is nevertheless much higher: COVID-19 took only 48 days to infect 1000 people.

According to a new Lancet study, this viral pneumonia is found mainly in the elderly or with underlying pathologies, in particular heart disease. It hardly affects children under 15 years of age.

What measures have been put in place to combat the epidemic?

The World Health Organization (WHO) now officially considers the epidemic as a “public health emergency of international concern”. She worries that the epidemic will spread to “countries with weaker health systems”. The WHO says limiting travel to China would be counterproductive: it could encourage illegal travel and thus facilitate the spread of the epidemic. In addition, the organization certifies that the situation does not have to be qualified as “pandemic”.

The WHO recently confirmed the “global shortage of personal protection,” including protective masks. However, she says that she regularly sends medical kits, gowns, gloves, and masks to many medical teams around the world. The WHO said the number of infections has stabilized but is not yet certain that the peak of the epidemic has passed. The WHO said the number of infections has stabilized but is not yet certain that the peak of the epidemic has passed. Tedros Adhanom Ghebreyesus, director of the WHO, said stopping the epidemic in China is “a big emergency” but that the virus remains a “very big threat” around the world.

The situation in Wuhan and more generally in China

The Chinese government has placed more than a dozen communities under quarantine – tens of millions of people. New municipalities have been confined (notably the one where the online sales company, Alibaba) is located. The latter only allows one person per household to go out once every two days to do their shopping.

In Shanghai, the Disneyland amusement park has closed its doors. The ski World Cup stop in China has been officially canceled.

The Chinese government has ordered the emergency construction of two hospitals near Wuhan to accommodate 2,500 COVID-19 patients. The first one opened on February 3. The second opened this Thursday, February 6. In parallel to this epidemic, China has announced the appearance of avian flu, H5N1, in a province south of Wuhan. Several thousand poultry have been slaughtered, but no human cases have been reported to date.

A hotline, intended for foreign nationals, has been set up in China. The Beijing Formula 1 Grand Prix has been postponed until April. The Chinese government has set up a system allowing its citizens to detect whether or not they have been in contact with a sick person. The Chinese government has exempted certain medical equipment from customs duties in order to supply it to help fight the epidemic.
