In order to be infected from a door handle, somebody the last few seconds had to sneeze in his hand, touch the handle, you'd have to really touch the whole handle and then take the hand to your mouth/nose. It is unlikely. They find virus RNA on surfaces but it is not activate. Infections from surfaces are vastly overestimated. Staying and talking with an infectious person in a room is underestimated.
