People tend not to go to hospitals for a lot of reasons. Number one? The wait. People have to weigh the worth of using an entire working day. I sure don't go to hospitals unless it's absolutely fucking dire, and even then I'll try to hold off until it's a weekend.

Number two? While you're waiting, there are a shit ton of other sick people waiting with you. For all the good hospitals do, they're pretty efficient at spreading disease as well. If someone isn't sure whether or not they have covid, why risk catching it or something even worse, like norovirus?
