You can do this via three doors (eyes, nose and mouth) and you are waiting for them to be opened. But if we touch contaminated surfaces and then rub our eyes or nose, we could expose ourselves to infection. So please put a “security guard” by the three doors. When hands come near any door, the security guard will “stop and question” what they’ve touched. When you are alerted by your security guard, you will remember to wash your hands before rubbing your nose or eyes.
