Of course you should wash your hands carefully before eating.
Also glasses and dishes should cleaned thoroughly.
But I dont think there are any virus on such a pizza (photo) fresh from the oven.
On the other hand if someone who is infected would cough and sneeze on the food (preparation -> eg salad) you eat after :
Not so good.
But if its cooked or baked I think it should be clean so far.
agree with you on this @Chiquinho
Yes, high temperatures seem to kill the virus very quickly. So you should be fine with anything cooked.
Salads you might want to stick to made at home for a while.
