evidence: At the moment, investigations are still underway to determine where SARS-CoV-2 originated and how it came to infect humans. Both the natural and lab leak hypotheses rely on circumstantial evidence that can’t prove nor disprove either theory. However, no credible evidence indicates that the virus was engineered. Based on prior disease outbreaks, the most likely hypothesis is that SARS-CoV-2 arose naturally and that zoonotic infections were the reason for the spread of the virus in humans.
