Where does the new corona virus COVID-19 come from

The spread of the New Coronary Pneumonia epidemic worldwide poses huge challenges to human health and the world economy. Faced with the problem of tracing the source of this brand-new virus, the World Health Organization, China, France and other parties are conducting scientific research. In contrast, some politicians in the United States have ignored science and used the epidemic to do their best political operations to discredit China on virus tracing.

In an epidemic of epidemic disease, you must first know where the enemy is, and you need to trace the source of the diagnosed case scientifically. However, in the United States, the timeline for the development of the epidemic is a complete “confusion”. On February 29, Washington State reported the first death case of new coronary pneumonia in the United States. Trump expressed his condolences with “she is an amazing woman”. But a month later, California announced that someone on February 6 died of new coronary pneumonia. The United States may have had a community infection as early as January. Recently, a mayor of New Jersey also claimed to be confident that he had contracted new pneumonia in November last year. Prior to this, Robert Redfield, director of the US Centers for Disease Control, publicly admitted that in the flu season that began in September last year, some of the deaths from influenza were actually infected with new coronary pneumonia. Straight from the beginning, one cannot but ask, how many of the flu patients in the United States have been misdiagnosed? When did the epidemic outbreak start? On such a critical issue, the authority has always lost its voice. One can’t help but wonder: Is the American high level really “ignorant”, or is it just to “scramble the pot”, deliberately ambiguous and muddy the water?

International community: The epidemic of the new coronavirus may be earlier than the discovery of China

As the first country to discover the new coronavirus and report to WHO, China is currently conducting a series of studies on the source of the virus.

In France, on May 3, local time, Professor Yves Cohen, the head of the intensive care department at two hospitals in the province of Seine-Saint-Denis near Paris, revealed when they participated in a live broadcast on French commercial FM TV that they By January this year, patients infected with pneumonia had re-tested the nucleic acid of the new coronavirus. As a result, a patient hospitalized on December 27 last year had a positive test result. This case has little to do with China, and there is no history of travel before the onset.

According to relevant papers published in the medical journal International Journal of Antibacterial Agents by the hospital, the 43-year-old man was born in Algeria and lived in France for many years as a fishmonger. His most recent trip was to Algeria in August 2019.

The confirmed diagnosis of this patient caused the emergence of confirmed cases of new coronary pneumonia in France almost one month earlier than the officially notified January 24, 2020. The hospital team said that it is not yet possible to confirm when and where the patient was infected with the new coronavirus, so it is also impossible to confirm whether this man is the first patient with new coronary pneumonia in France. Professor Cohen called on hospitals in other parts of France to also carry out retrospective testing of samples of unknown pneumonia patients since last winter.

Regarding the new discoveries in France, WHO spokesman Christian Lindmeyer said at a press conference in Geneva, Switzerland on the 5th that WHO encourages countries to re-test some recent samples of unexplained pneumonia cases, “New discoveries We are given a new picture of all aspects. Of course, it would be great if all countries could re-test the new coronavirus for unexplained pneumonia cases in the near future, even in November and December last year. ”

In addition to France, American researchers have also made new discoveries. The latest test report from Santa Clara County, California, showed that as early as February 6th, some people died of new coronary pneumonia, which was more than 20 days earlier than the first death of new coronary pneumonia announced by the US government. Santa Clara County Chief Executive Jeffrey Smith said that this shows that the new coronavirus has begun to spread in California as early as January or even earlier.
