Well, we can't avoid getting in touch with germs and you know that. In our hospital, all patient's room have this hand sanitizer dispenser wherein visitors, HC professionals can use before touching the patient and before leaving the patient's room. This can prevent cross-contamination. It doesn't take more time than doing the handwashing if they're in a hurry. The patient can also use it if he/she wants/needs to. Moreover, children aren't allowed to enter the hospital premises as a visitor. Security guards implement this strictly. If parents really insist to let their child enter then they need the permission of the infection control committee to be allowed to, so that precautions can be followed. Furthermore, immunodepressed patients should be put on a reverse isolation precautions.
