A new strain of Covid-19 encountered in Brazil

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

According to the report of the South China Morning Post, researchers from China’s Wuhan Institute of Virology stated that the Corona viruses belonging to this new branch are the “distant relatives” of Covid-19.

The researchers noted that the result of the study was that the Corona virus species discovered from bats could only be the visible part of the iceberg for now.

The World Health Organization (WHO) delegation investigating the origin of the new type of Corona virus (Covid-19) reported that there is no evidence that the virus originated from the food market in Wuhan.

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

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

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


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 carried out 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 Disease Center.


The world was first informed of the Covid-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 food market in Wuhan, and the first patient applied to the hospital on 17 November with the complaint of “respiratory illness” whose cause was unknown.

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