Thanks for commenting. As Peter noted, the information that Wuhan research lab scientists got sick is an unreliable information. Subsequent efforts have failed to confirm this information (I added this slide in the Appendix). Moreover, based on the Wuhan lab prior activities, the researchers kept on publishing during that time. While this does not prove they were not severely ill, at least it doesn't match the unreliable information of sick Wuhan scientists.

Thank you for congratulating, and I understand you may not be able to take much from this article. The natural vs. lab origin topic is vast and I can't cover everything in this article.
