I don’t think so. I mean, about needing to have break in the skin. Many doctors have died, having merely touched a patient.

I agree. You can make yourself ‘bleed’ just by lightly rubbing your skin with your hand.
You don’t actually see the blood, but it is there. You would see a wound under an electron microscope. Albeit, very small, but significant enough to allow penetration of a virus.
