In other words, there is no identifiable locus of the virus. It doesn’t matter whether the virus is transmitted among the community, or brought in on a plane or train. It doesn’t matter whether we have been globally exposed or locally situated, the virus is all around, and it could be transmitted by any of us. And even though I might feel well, I have been infected and have transmitted it to others before I even knew I was sick. How terrifying is that?
