I honestly think the medical and health care professionals are our own worst enemies. I sit on some of these committees and we hear some of the debates about how and where we should use this. From a medical standpoint, we have to be extremely careful. From a public health standpoint, of course you still need to be careful, but there's a little bit more wiggle room in how you can use these tools. You can certainly set up protocols to use them.
Unfortunately, I think we're perhaps treating a screening tool more as a diagnostic tool. The question we're answering with these is: “Is the person at risk of transmitting the infection?” not “Is this person infected?” It sounds similar, but it's actually quite a different question.
We have ourselves to blame for a lot of this.
