The virus in its various guises has been studied for over 50 years and monitored yearly with strains know at the time.Interesting theory but I'm looking at this as more of a thought experiment, where SARS-CoV2 went under the radar as a nonlethal virus that didn't cause any significant symptoms for longer than we realize and only recently mutated to the deadly virus we now know. Would these 2 viruses be the same genetically? There's obviously something physically different about the mutations we know of, Alpha, Beta, Delta, etc. but they are all SARS-CoV2. Would a hypothetical pre-mutation, nonlethal, version of SARS-CoV2 be recognized as SARS-CoV2?
Investigations are ongoing (to the best of my knowledge) in reference to a 2012 outbreak in China although the link also refers to 2004.

Thank you for the link... I note the paper was not peer reviewed and the authors created a second paper where they removed the reference to March 2019 in Barcelona.This is the source from the article: https://www.medrxiv.org/content/10.1101/2020.06.13.20129627v1
