Question #1: False Negatives ()
Subject: Should we be worrying about false negatives for Coronavirus testing?
Message: I've been seeing claims on Facebook where people state that COVID19 testing is "30% inaccurate," is just a placebo, and that we should not even bother with it. No citations of course, but I think they are referencing this article: The Conversation: Coronavirus - How accurate are Coronavirus tests?[6] I'd love to hear a more in depth analysis of the subject!
