How are germs transmitted?

Germs can be transmitted in many ways,but the most that are very comment are airborne,meaning its impossible to Dodge germs if they are in the air.

The second most comment is contact,as our hands touch so much stuff,its true that we touch our own face a lot so its inevitable for germs to NOT be transmitted.

Other unknowns are unclean utensils,unclean surfaces etc.
