> Assuming a lab leak they may well be aware of these effects already from previous research and therefore enforce zero-covid to avoid it because it's riskier than we currently understand. You're reading way too much science fiction or something. We're two years into this virus with the combined effort of the entire world's scientists trying to determine why it causes loss of smell and we barely have an explanation so far. The Chinese did not unravel the mysteries of SARS-CoV-2 anosmia before the pandemic ever started. Once again in a conspiracy theory the conspirators are both completely incompetent (the lab leak) and nearly omniscient (the ability to engineer SARS-CoV-2 from scratch and determine all its properties and keep all the research perfectly secret).
