Which laboratory did Corona come from?

One cannot say with certainty that a laboratory was the cause of the pandemic. Although technically it would be possible to produce such a virus as an “experiment”, one can wonder what it would be good for. The genetic material of the Covid-19 pathogen does not have the typical manuscript that should leave such experiments.

On the other hand, the virus has broken out in Wuhan. There is the Institute of Virology at the University of Wuhan, which was the world leader in the experimental research of coronaviruses. Experiments with genetically manipulated coronaviruses were also carried out there.

The statements and behaviour of the staff of this institute were not exactly encouraging to confirm that the virus was not released from this laboratory by an accident. They could have let international inspectors into the laboratory at a time and it would have been possible to provide their virus database for the search for the origin of the coronavirus.

This database was public once, but no one had made a complete copy.

The most similar known virus with Covid-19 lives in over 1000km south of Wuhan. You don’t know how the virus came to Wuhan. Since there is no other explanation of what was expected at the beginning, you can speculate that it has something to do with the laboratory. You can’t prove that.
