Where did Covid-19 come from? The answer can be found in the SARS-CoV-2 virus itself. To get to the truth, we need only unleash the power of science.

Based on experience with SARS-1 in 2003 and MERS in 2012, we know that many people are infected by a host animal long before a coronavirus mutates to the point where it can jump from human to human. An extensive data set from late 2019—more than 9,000 hospital samples—is available of people exhibiting flulike (thus Covid-like) symptoms in China’s Hubei and Shaanxi provinces before the epidemic started. Based on SARS-1 and MERS, the natural zoonotic theory predicts 100 to 400 Covid infections would be found in those samples. The lab-leak hypothesis, of course, predicts zero. If the novel coronavirus were engineered by scientists pursuing gain-of-function research, there would be no instances of community infection until it escaped from the laboratory. The World Health Organization investigation analyzed those stored samples and found zero pre-pandemic infections. This is powerful evidence favoring the lab-leak theory.
