In terms of how it is different to other people going to work, when I was in work (now WFH), I went to one location, washed my hands constantly, wiped down my desk and computer, used hand sanitiser, made sure not to touch my face etc.
At home, I wash my hands when I get in, wipe down perishables before putting them in the fridge / freezer and leave the clothes / bags / non-perishables I wore / brought in from outside in the second loo that I don’t use for 3 days.
I then don’t worry about washing my hands (other than after the loo, when showering, before eating as I did pre-virus), touching my face etc. I am basically fairly sure that unless I have picked it up outside (more than possible), my flat is virus free.
There is no way I am having a random person (people) who could be infected or have the virus on their clothes or cleaning equipment from another client’s house in my flat, particularly as cleaners go to house after house - which must increase their chance of transferring the virus from one place to another.
I use an agency and have never met my actual cleaners. I’m fairly sure that if I kept paying, the actual cleaners wouldn’t see the money so I’m not going to.
