I made some stock trades this am based on this news (bought BNTX, reduced market exposure) and think it’s at least credible that this could be qualitatively worse that what we have now. Might not be in the end (hopefully), but govt actions can be worse than the disease too and those might be prompted as well if it looks bad and they feel they need to “lockdown even harder” or whatever. But it’s already spread to half a dozen countries, at least in small numbers, and probably moreso once they actually start looking carefully for it.
