Well, since my significant other is a nurse and she is on the frontlines, I have some insight into this. Here is the difference with CoVid. Having an N-95 mask on and then having a surgical mask over that and working 12 to 14 hours on your shift is very difficult on those workers. They have a hard time breathing and the N-95's masks hurt, mark and bruise their faces. There is also an emotional toll that it has on Doctors, nurses, respiratory therapist, etc. despite the fact that they deal with disease everyday. The more they get exposed, the greater the chance that they can be a victim of a breakthrough case. CoVid has not been business like usual for healthcare workers. They are tired of CoVid and want to get back to normal. Their job is stressful enough.
