DH works in an office that will not be closing. All work COULD be done from home, but they are refusing to close, refusing to let them stop seeing clients.

I have asthma and DD has a weak immune system. What's our best way for DH to avoid this and avoid bringing it home? He's been washing his hands when he gets in, and changing his clothes, is showering better? He uses the hand sanitizer when he gets into the car too and wipes the steering wheel with Dettol wipes, and all the door handles.

He has to travel for an hour as well, to get to this job, it's not even local. I'm so scared in case he catches it, he's healthy and young but that doesn't seem to mean anything.
