(CNN) – The team investigating coronavirus origins in Wuhan, China, has identified the scenarios that are likely to cause covid-19 transmission to the human population, said World Health Organization expert Peter Ben Embarek.
“Our initial hallucinations suggest that the introduction of a species to an intermediate species is the most probable and a form that will require more specific studies and investigations,” said Embarek during a press conference.
It was also noted that the possibility of transmission through the trade of congelados products is likely.
Embarek also signaled other hypotheses that the team had investigated while investigating the origin of the virus.
A hypothesis was a “direct zoonotic direct”, that is, direct transmission of an animal reservoir to a human.

“The hypothesis of a direct drama from an original animal source to the human population is also a viable one and is also generating recommendations for future studies,” he said.
The fourth hypothesis was the probability of an incident related to the laboratory, but this was the least likely of the four.
“The hallucinations suggest that it is extremely unlikely that the laboratory hypothesis explains the introduction of the virus into the human population,” said Embarek.
The first cases of covid-19 of the Huanan market broth are likely to infect the December 2019 principles or the November 2019 finals.
“In terms of time and place, what we know are some of the first cases that may be reported in the market if they detect the indication of symptoms in the first weeks of December, which indicates that it is probably infected in the December principles or the finals of November «, Embarek said at a press conference during the investigation of the WMS team in Wuhan on March.
“But we can enter in more detail with the information we analyzed,” said Embarek.

Embarek also said that its team found evidence of a greater circulation of covid-19 from the Huanan market of broths in December 2019.
“Only the broth in Huanan’s market was flown, meaning that the virus also circulated in the market,” he said.
Embarek agrees that the image of the team regarding the origin of the virus before the investigation did not change drastically, but the owner obtained more information.
“Do we drastically change the image we have of antiquity?” No lo creo. ¿Agregamos turn off? Absolutely », says Embarek.
China Health Officer says experts do not identify SARS-CoV-2 on New Year’s Eve in China

At a joint conference of the World Health Organization in China in Wuhan on March, Liang Wannian, head of the Expert of the Response COVID-19 of the National Commission of Health of China (NHC) said that the studies and investigations « no han logrado identify evidence of SARS- Virus related to CoV-2 in wild silver samples in Wuhan and different places in China ».

Liang Dijo said Huanan’s market leader indicated that it had a “generalized contamination of surfaces” with SARS-CoV-2 at the time it was closed.
Dijo que el hallazgo era «compatible with the introduction of the virus of infected persons or products related to the holiday chain, animals and products of animal origin» and that the investigation of related products with the holiday chain needs more research.
“According to this investigation, all the models related to animal products or negative animals. For the products of the holiday chain and the relevant tests, the investigation will take place in one step in the course », Liang said.
Explained that the virus can “persist in the conditions found in processed foods, foods and products of the holiday chain”, and that “recent crimes in China are related to the holiday chain”.
