While KOVID-19 travels around the world causing location, pneumonia and fear, scientists fight the source of SARS-CoV-2.
Although all the answers – if they came from the animal reservoir – are not yet available, the new research has certainly sparked conspiracies to claim that it is a laboratory-born disease.
The study offers fascinating insights into the origin of the latest coronavirus. One example suggests that the virus may have passed harmlessly through a person for a long period of time before it became a pandemic that paralysed the world.
Research has shown that the ancestor of SARS-CoV-2 can be assumed to have entered the human body and to have been acquired by modification during the process of transmission of the undetected virus from person to person.
Researchers analysed the available data on the SARS-CoV-2 genome. Other related coronaviruses, which demonstrate that the receptor binding domain (RBD) is one of the most important proteins of SARS-CoV-2 They are so effective in their interaction with human cells that they need to be initiated by natural selection. If this additive effect is achieved, the disease will break out and lead to a fairly large number of cases.
The two characteristics of the virus, the ISD mutation of the solder protein and the clear signal path, make it difficult to work in the laboratory with SARS-CoV-2 as a possible source. The team tested two plausible theories, the interruption of the laboratory experiment failed. The natural selection was then carried out before the virus was transmitted to humans as the master of the animal. The team explains that although studies on coronaviruses have shown similar genomes in bats and pangolins, none of them are a perfect match.
Although no animal coronaviruses were found near the direct precursor of SARS-CoV-2, the researchers state that widespread coronaviruses are not released significantly in bats and other animals. The second possibility is that natural selection in humans takes place after the virus has been transmitted by the host animal.is covid 19 airborne cdc,is coronavirus airborne
