(CNN) – The coronavirus pandemic on smallpox, shows a new study.
Investigators who are working to sample and come up with the virus first and foremost in China calculate that the virus may not have been infected before humans in October 2019 as very soon. And his models will show some more: for smallpox does not contain a pandemic virus.
Only the poor and the abusive conditions of Huanan’s market in Wuhan, the place where he appeared to have started the pandemic, the animal in the virus that is necessary to explode all over the world, informs the researchers in the journal Science.

«Fue un tormenta perfecta; now we know that the virus carries one of the waves of success to establish firmly, “said CNN’s Michael Worobey, a professor of evolutionary biology at the University of Arizona who works in the studio.
“If the Huberan cases are a different one, if the first person to be in Huanan Hubera’s market has decided not to do so, this includes whether or not he will be placed in solitary confinement and he will simply be fined at home, it is possible that he or she will superpropagation temprana no hayan ocurrido. It is possible that no hubiéramos sabido nada ».
How will the covid-19 pandemic be restored?
The team employs the molecular data, using the cycle of mutations in the course to calculate how long the virus has existed. We will also be implementing computer models to show you how to grow and grow plants.
“Our study was designed to respond to the question of the time when the SARS-CoV-2 was circulated in China before it was discovered,” said Joel Wertheim, associate professor of the Division of Infected Diseases and California Faculty of Medicine of San Diego.
To respond to this question, we combine three important pieces of information: a detailed understanding of how SARS-CoV-2 promotes Wuhan before the confinement, the genetic diversity of the virus in China and the information on the first cases 19 of China. Combining these distinct lines of evidence, we will establish a superior limit in mid-October 2019 when the SARS-CoV-2 begins circular in the province of Hubei ».
Evidence clearly indicates that the virus could not have been circulating before then, investigators said. It was reported to Italy and other European countries that the virus could have infected people before October. Peru the study of juveniles indicates that only a dozen dozen people will be infected between October and December, said Worobey.

“Thus, it is difficult to conceal these high levels of virus in China with the claims of infections in Europe and the United States at the same time,” said Wertheim in a statement.
“I’m pretty skeptical of the claims that covid-19 was driving China at the moment.”
The study indicates that the virus surged in the Chinese province of Hubei and not in other places, the investigators said.
“Our results will also reflect the affirmations of a large number of patients requiring hospitalization to covid-19 in the province of Hubei in December 2019,” he wrote.
From a crackdown on cases to fines from 2019, the virus exploded all over the world. According to Johns Hopkins University, 121.7 million people were diagnosed and 2.7 million were killed. United States has, by far, the most affected country, with around 30 million diagnosed cases and 540,000 deaths.
I do not know what animal was at the point of covid-19
The study did not show that animals were the source of the virus. The genetic evidence shows that murmic societies are carriers of a highly related virus and also suggest that another animal species is likely to be infected and transmit the virus to a human being in some place.
This is not the case. The Centers for Control and Prevention of Infants of EE. UU. rastrean and informan regularly about cases of new influenza cephalas that infect people who assist during holiday periods and interact with cats, for example. But now, none of these infections have provoked an epidemic, including a fever.
What is needed is an infected person and a lot of contact with other people, as well as a market of densely populated markets. “If the virus does not have the ability to detect its circuits, including a well-adapted virus, it can disappear,” Worobey said.

“From the perspective of algae: these events are likely to be associated with much more frequency than what we are talking about. “Simply (the viruses) do not read it and we will not listen to them,” said Worobey.
And so I had to deal with covid-19.
In the models that execute the team, the only virus is active around 30% of the time. The rest of the time, the model shows that deberia haberse extinguished after infecting a pup of people.
“It’s been reported here that the virus has spread to a large number of people in October, November and December and has entered Huanan’s marquee market,” said Worobey.
It is probable that the market is not at sea where the virus has infected the people for the first time, only the place where it is amplified.
Dado el poco tiempo que stuvo presenten vir virus, is opmerklik que se haya identifican tan rápido, dijo Worobey.

“It was quite clear at some point in December, before a group of infected people were sufficiently infected, that they had the possibility of discovering a new virus,” he said. For the year 2020, it has been sequenced and characterized.
Geen hindernis, era demasiado tarde, tal vez porque el covid-19 no es lo sufficiente mortal. The first SARS virus killed about 10% of its victims between 2002 and 2004 before detecting a concerted world war.
As a scientific community, we are certainly aware of the pandemic potential of a moderately virulent and highly transmissible pathogen. For our hospital notification system depending on the detection of photos in hospitalizations and deaths. Claramente, eso no fue suficiente para detener el covid-19 », dijo Wertheim ‘n CNN.
