You can leave that cardboard package at your door for a few hours — or bring it inside and leave it right inside your door, then wash your hands again. If you’re still concerned there was any virus on the package, you could wipe down the exterior with a disinfectant, or open it outdoors and put the packaging in the recycling can. (Then wash your hands again.)
Shop when you need to (keeping six feet from other customers) and load items into your cart or basket. Keep your hands away from your face while shopping, and wash them as soon as you’re home. Put away your groceries, and then wash your hands again.

If you need to use something immediately, and want to take extra precautions, wipe the package down with a disinfectant. Last, wash all fruits and vegetables as you normally would.
.....if you take basic precautions, including washing your hands frequently, the danger from accepting a package from a delivery driver or from takeout from a local restaurant or from buying groceries is de minimis. That’s a scientific way of saying, “The risks are small, and manageable.”
