Coronavirus has a natural origin

Scientists in areas with circulating conspiracy theories, according to which the novel Coronavirus called SARS-CoV-2 produced in the lab was supposed to be: A meticulous look at the genetic material of the Virus showed no evidence that the Virus was artificially manufactured.

Corona viruses are a large family of viruses, which cause diseases with varying severity. Soon after the beginning of the epidemic decrypted Chinese researchers the genome of SARS-CoV-2 and provided the data. "Through the comparison of the available genome sequence with the known Coronavirus strains, we can see clearly that the SARS-CoV-2 by natural processes created ist", Dr. Kristian Andersen, a Professor of immunology and Microbiology at the Scripps Research in California, said.

The genetic structure of the Virus speaks for a natural process: If someone had tried to develop an artificial pathogenic Coronavirus, he would have designed it from the backbone of a Virus, which is known that it causes diseases. That was not the case. Rather, the basic structure of SARS-CoV-2, the viruses that have been found in bats and pangolins, is similar to. In addition, the mutations to speak of a certain Protein that the Virus binds to human cells, to ensure that they are the result of natural selection.

The emergence of SARS-CoV-2: Two theories are conceivable

There are two possible theories on how the Virus developed, it could have: It could have been in animals so that it was pathogenic and directly or via an intermediate host to the human skip was able. Another possibility is that the Virus is transferred as a harmless variant on the people and only after mutations have occurred, it was the causative agent of a severe disease. Which of the scenarios is true, you can’t say just yet.
