Your quarterly PSA about being sick

Why does this have to be repeated? But here we go...

If you're sick, either stay home (esp if fever is present), or wear a mask, use sanitizer, wash your hands, cover your mouth and distance yourself. You are putting everyone else around you at risk, including those with autoimmune conditions. Be considerate and also put your own health first.

PS it is very disturbing and unethical when a professor tells you that you still need to come in if you're sick unless you go to the Dr. and get a note.
