It's interesting that people are only applying this level of precaution to covid when (if they were consistent) they would probably apply it all the time to every novel viral strain. If the far-off chance of covid causing some crazy complications down the line is enough to warrant partially shutting down civilization, then we should probably all just live in hermetically sealed bubbles on account of the possibility of the hundreds of more obscure but (cumulatively) more dangerous viruses out there.
