For a few months basically no one knew how it spread. I look back and think about how it could be seen as overboard, but being cautious and careful is more important in a time when something like Covid was quickly spreading and had these wildly different experiences for people. Especially the first alpha variant which seemed to either kill people, or cause them to not smell/taste and have memory issues. I wasn’t going to fuck with that, and still don’t want to.
Also, some forget, but there was a lot of videos coming out of China where it started with people running around seemingly trying to infect others and felt very zombie-esque.
