Some good advice here.
From a hospital medic I was told:
Have a washing up bowl with a water and bleach solution by whichever door you all come through. Dip shoe soles and leave shoes outside.
Open door but try not to touch keyhole or any handles. You can always dunk your keys in the bleach solution after opening the door.
Strip off all clothing (or just outer clothing if not returning from a super high risk area) and put straight in the wash. ANY detergent or soap will break down the walls of the virus cells so multiple clothes can be washed together. But place carefully in machines and put on immediately. Doesn’t need to be a hot or particularly long cycle, the detergent is what is key.
If coming back from a high risk place, like your DH will be, Immediately shower, including hair. The virus can cling to hair. Ideally keep hair tied up when out and about.
Drink constantly throughout the day, but sip tepid or warm drinks every 15 minutes. Avoid icy cold drinks. Drink lots of lovely tea!
Obviously, wash hands repeatedly, but namely when coming in from outside.
Routinely wipe down anything with that will be touched by a third party, not from your household, such as letter boxes, milk bottles, door knocker etc.
Leave any shopping bags outside (UV will also kill off the virus) and wipe down all shopping before bringing it in.
All this sounds overwhelming but we’ve managed to make it routine and obviously, we’re not going out much anyway.
Good luck and stay safe.
