A new branch was found in the family tree of coronaviruses seen in bats


According to the report of the South China Morning Post, researchers from China’s Wuhan Institute of Virology stated that the coronaviruses belonging to this new branch are the “distant relative” of the cause of Kovid-19.

The researchers noted the conclusion of the study that the coronavirus species discovered from bats may only be the visible part of the iceberg for now.

The World Health Organization (WHO) delegation, which investigated the origin of the new type of coronavirus (Kovid-19), reported that there was no evidence that the virus originated from the food market in Wuhan.

Russian expert Vladimir Dedkov from the WHO delegation said that there were all conditions for the spread of the epidemic in the food market in Wuhan, but this did not mean that the virus originated from there.

The institute, which was established to create an archive with the genetic information of bat coronaviruses after the Acute Respiratory Syndrome (SARS) epidemic in 2002-2003, was the subject of allegations that “Kovid-19 was artificially produced in the laboratory here and went out by mistake”.

Chinese officials denied the allegations, and made counter claims that “it is not proven that Kovid-19 originated in another country and came to the country with imported frozen seafood.”

China declined calls for investigation

China previously rejected the US administration’s request to initiate an investigation into the origin of the virus, and imposed export restrictions on this country after the Australian government called for an international investigation into WHO in April 2020.

Later, after the increase of international pressure, the delegation consisting of experts and researchers from the USA, Australia, Germany, Japan, England, Russia, Netherlands, Qatar and Vietnam first went to China at the beginning of January, but to return after the Beijing administration warned that valid visas were not received. had to.

After obtaining the permits, the delegation, which came to the city by private plane on January 14, was kept in quarantine for 14 days, during this period, they exchanged information with Chinese officials online.

In the field studies that started on January 29, the delegation conducted examinations in the seafood food market in Wuhan, where the first cases were seen, as well as Hubey China and Western Medicine Integrated Regional Hospital, Wuhan Jinyintan Hospital, Hubey Province Disease Control Center and Animal Diseases Center.

Kovid-19 was seen for the first time in the food market in Wuhan

The world was first informed of the Kovid-19 outbreak when it reported to WHO that “mysterious respiratory illness of unknown origin” emerged in Wuhan city of Hubey province on December 31, 2019.

The disease was first seen in people who visited the seafood market in Wuhan, and the first patient was admitted to the hospital on 17 November with the complaint of “respiratory illness” whose cause was unknown.

It was understood that the disease that causes lung inflammation was caused by a previously unknown type of coronavirus, which is predicted to be a mutated beta coronavirus found in bats.
