I don’t understand why people think it’s more likely to come from a lab rather than a zoonotic infection. China has routine cases of Plague because people eat Marmots and other animals every year and no one claims it’s a lab release despite their significant plague research program. Was SARS a lab release too? What about MERS? what about the countless other coronaviruses that are known to be in bats and other animal species? Think about how often zooonotic infections occur every day and then think about the number of reported laboratory associated infections. Never mind the fact that Bsl-4 labs have the most strictest safety regulations that mitigate accidental infections without some idea of breach of containment to zero and that there is no mention of lab workers at the facility being infected.
