As the world debates the origin of SARS-COV-2, most assume the SARS outbreak of 2003 was a natural event. But revisiting the evidence I found parallels, direct linkages and many unresolved questions.
To understand the origin of SARS-CoV-2 it’s illuminating to revisit the history of the first SARS outbreak and the subsequent investigation of its origin. SARS is assumed to be the result of a natural zoonosis by most scientists – including many who are open to an artificial origin of SARS-CoV-2. But the basis for this assumption may be unsound. There are many parallels between the two viruses both at the molecular level, and also in the epidemiology, pandemic management and origins tracing. Many of the same individuals and institutions play key roles in both. It may be that these outbreaks aren’t independent events, but the result of a long-term research program.link
