A new paper claims SARS-CoV-2 bears signs of genetic engineering

The nightmare of covid-19 began with a string of about 30,000 genetic letters. The exact beginning of this story has been a point of contention. The emergence of covid-19 is thought to be a spillover of a group of coronaviruses found in bats. There is an enthusiastic coronaviruses engineering going on in laboratories around the world, but particularly in the Chinese city of Wuhan, where the first case of the virus was found. A team of scientists assembled by the World Health Organisation said a laboratory leak was not likely. This conclusion was challenged by the WHO boss who said it was premature to rule out this theory.

The case for a natural origin connected to a " wet market" has been strengthened by two recent publications. Live animals are often housed in poor conditions and are known to be sites where new pathogens jump from animal to human. There were early cases of covid-19. Critics say that there are so many missing data that this portrait may be incorrect.
