True. I suppose you could wipe down everything you touch if you want to minimize your exposure even further but shopping cart handles are the things we can pretty much guarantee someone else has been handling.
I've run out of food and have to go get it today. I'm putting on mittens.
There's only one reported case in my town - one of about 20 in The Netherlands. The person is at home and not allowed to go out - his/her family members are allowed to go out though for necessary things - so it can spread through them. I don't know why they don't put infected in total quarantine, but I suppose they see that as inhuman or something.
Anyway, I'm not directly in the risk group I think. I'm not a smoker and not that old. I also have quite strongly OCD and always wash my hands about 40-50 times anyway each day, I would guess.
