After this epidemic the world is going to be concerned about the spread of viruses.  Someone is going to need to constantly walk around offices and disinfect doors, and everyday things.  Figure out a way to make door handles that are enclosed in a blue light. 

The reality is that the virus isn't going away anytime soon. I say a webinar type of class teaching office staff and businesses how to be clean and sanitize.  Personally the Ideal of everyone walking around with face masks is absurd.
