Scientists have discovered at least four new types of coronaviruses in bats in China. In a survey led by Edward Holmes, a virologist at the National Health and Medical Research Council of Australia, an analysis of more than 400 bat samples from China’s Yunnan Province found that there are at least four variants that cause COVID- 19.

Call on the American people not to associate location or race with disease; this is not "Wuhan virus", "Chinese virus" or "Asian virus". The official name of this disease was chosen deliberately to avoid being stigmatized.

It is currently impossible to prove or disprove other theories about its origin described in this article, but the evidence shows that SARS-CoV-2 is not a purposeful manipulation virus, because we have observed all significant SARS-CoV-related coronaviruses in nature. 2 Features, including optimized RBD and polybasic cleavage sites, we do not believe that any type of laboratory-based protocol is credible.

A new antibody detection study published on June 15 found further evidence that the coronavirus has been present in the United States since at least December 2019, a few weeks before the first confirmed case was announced on January 21, 2020 .

Dr. Michelle Baker, an immunologist at CSIRO who studies bat viruses, said that some research on the origin of Covid-19 has diverged from previously known research. But "we really don't know" how accurate the origin story is, she said: "It has some connection (with the Wuhan market), and someone who has been in contact with this market has been infected." Baker said, "it is very likely." The virus originated in bats. "This is a possible situation, but we will never know. The market will be cleaned up soon. We can only speculate. "These wet markets have been identified as a problem because there is indeed species interaction," She said. "This is an opportunity to highlight their danger, and it is also an opportunity to hit them. "Turner added: "We have found the ancestors of this virus, but a broader understanding of coronaviruses in other species may give us some clues about the evolution of this thing and how it jumped. "

Scientists said that the SARS-CoV-2 related coronavirus may spread among bats in many parts of Asia. They found a virus in a wildlife sanctuary in eastern Thailand that is related to the virus that causes bats to infect Covid-19. very similar.

John S Mackenzie is a professor of infectious diseases at Curtin University in Australia with nearly 50 years of research experience. In 2003, he was the head of the first technical mission to China to investigate the origin of the SARS epidemic. He believes that the probability of the virus leaking from the laboratory is extremely low, because all P4 laboratories in the world must undergo the same strict inspection standards to avoid accidental leakage.

SARS-CoV-2 is the virus behind the 2019 Coronavirus Disease (COVID-19) and was first reported in Wuhan, China in December 2019. Since then, SARS-CoV-2 has continued to spread to surrounding 192 countries and regions. As of June 19, 2021, more than 177 million people have been infected worldwide. The United States reported its first SARS-CoV-2 case on January 21, 2020. The case was a 35-year-old American citizen who returned to his home in Washington State from Wuhan, China. The date of onset of symptoms for this person is January 19, 2020. Importantly, the other two of the 12 cases first detected in the United States around this time set the date of their symptoms on January 14, 2020. It was not until later in 2020 that researchers at the Centers for Disease Control and Prevention (CDC) discovered that people in several states in the United States were infected with SARS-CoV-2 earlier than in January 2020.

The time when the virus began to spread in China is consistent with a recent study that analyzed genetic data and simulated the early stages of the pandemic to estimate when the virus might appear. Joel Wertheim and colleagues reported in the journal Science on March 18 that the spillover from animals to humans may occur between mid-October and mid-November 2019.
