@Spudlet the pepper visual tool is fantastic! My children are older now, so get the idea of why they need to wash properly, but a few years ago this would have brought it alive for them properly.
I am happier today because my colleague, whom I was really worried for due to underlying conditions has begun WFH. DH has also been WFH, so he has calmed down a lot (he has asthma, and health anxiety and is stressed also about his elderly mum).
We set-up Skype to his mum last night, and spent about forty minutes chatting with her, so that was great, and has alleviated a lot of his worries. 
I am listening to classic FM, which is nice and calm, with only two minutes of news on the hour (so easily avoided if you want).
Although I'm in the office, I am fortunate enough to have an office to myself, and drive to and from work in my car, and stay pretty self-contained for most of the day. I think maintaining normality wherever possible is good for my emotional health.
