Anxiety over sickness bug

[Bexlily]

My son had a sickness bug over the weekend, he last vomited on Sunday lunchtime.

Since he's been ill I've been extremely anxious about getting it, I don't have a vomiting phobia and have looked after him OK, I just don't want to get ill.

I know that the chances of me starting with it now are very slim but I can't stop thinking about it. I didn't use to be like this, it's only since worrying about Covid that I've started to get anxious over illnesses.

What can I do to reduce this anxiety?

I don't have much in the way of advice. Only to say I'm exactly the same, again since Covid, so you're not alone in this thinking.
The only thing that works for me is distraction, so finding something to do to keep my mind off it. Or reminding myself that if I did get ill, I'd likely get over it ok.
