How much danger in exposure to disease does seeing a doctor present?

For instance, someone posted about germy neckties. Presumably true – but how often does someone catch an infection via necktie? Patients aren’t going around licking neckties, or sniffing deeply into one, or anything like that. And even if a doctor leans in and brushes his necktie against one’s arm or even cheek … that’s not insta-infection – probably just incidental touching of germy things like that doesn’t commonly spread illness.

You can adjust your germ-filled necktie, and later touch your eyes, nose or mouth with your now germ-laden fingers.
