How to avoid germs
Take a shower shortly after being around someone who is sick.
Use antibacterial soap if the person was unwell with a contagious condition. There's no need to do this if you've been around a person sick with something non-communicable, like cancer, or a migraine.

Options:
[a]. Avoid using other people's food utensils. Never eat off someone else's plate or drink their beverage.
[b]. Using one of these antibacterial soaps or bathing outside the bathroom allows bacteria to set in and make you more confident that the person will have a good time. See a doctor if you have a virus.
[c]. When making a cold wash with cold water, be gentle and avoid combining cold water with any soap. Avoid putting any clothes or linens in a warm tub after a cold wash for the same reason.
[d]. Steam a tea made from water and fresh flower leaves or place 3 leaves in a cup of warm soapy water (tea cups are sometimes made as sandwiches). You can use this to wash your face and body.
[a].
