Hospital elevator buttons carry more bacteria than toilet surfaces

And since we are very likely to  need to use the elevators because of our impaired walking ability let your doctor or therapist push the buttons for you. They can handle any infection much better than you can.

Canadian researchers at the University of Toronto found that bacteria commonly colonize on elevator buttons, although most pathogens were not clinically relevant, according to a study published in Open Medicine.
Researchers swabbed 120 elevator buttons and 96 toilet surfaces over separate intervals at three large, urban teaching hospitals on weekends and weekdays in Toronto, Ontario. They swabbed the up and down buttons on the outside of the elevator, along with the ground floor and a randomly selected upper-level floor button, while they swabbed the handles of the bathroom door, the privacy latch on the door and the toilet flusher.
