No paranoia as far as I'm concerned, just good sense. I would suggest that food containers that can be frozen and then cooked from that state are not likely to be a problem if you use a microwave or oven to reheat. If you are worried about essential mail you could also microwave for a FEW seconds or open outdoors or spray with a soap solution before opening.
I have cardiac problems/copd/diverticulosis/costochondritis/ possibly rhabdomyolysis or similar and an as yet undiagnosed tremor .
Needless to say my appointments are cancelled.
Did manage to shop for food/drink today so we can eat and drink!
All of us need to take care and use family to help at a distance. I f you have a thermometer use it daily on each other, spend time with each other or garden /workshop.
Just stay safe everyone. Nathan.
