The surface area of contact for a finger is significantly larger than the end/edge of a key and so although some may transfer, it matters how much contact is made.

I understand that but still feel it's sorta useless precaution. Like just wash your hands more often or make it a habit to carry anti. Bac. And when going in and out of public buildings and bathrooms get In the habit of using it. Maby not every time you enter a public building. Idk if you use a public restroom and when your done running errands for the day. You need some natural immunity

Touching a surface with a finger will transfer on average half the contamination over a finger tip. Or a palm. Touching that to your nose is half that or 1/4.
Now touch the surface with the tiny key tip. If it's 100 times as small that would be not 100 less but 10, 000 times less dosage. For a palm on a door handle it could be millions less.
