People who are contaminated touch things.
Then you come along behind them and touch what they have touched.
Then you subconsciously touch your mouth, your nose, your eyes, or your food.
Now you have become contaminated.
If your life involves primary or secondary contact with other people,
you should wash your hands frequently to wash away the contamination.
The more often you are in contact with other people,
the more often you should wash your hands.
Simply scrubbing your hands together under running water will remove 90%.
Using hot water might give you a couple more %.
Using soap might give you a couple more %.
Using antibacterial soap might give you a couple more %.
...but just the very simple mechanical action
of scrubbing your hands together under running water will remove 90%.
This is true now and always under every condition with every virus.
If you don’t get out much, then it doesn’t matter much.
A retired person sitting at home has much less risk
than someone who is a flight attendant or a doctor or a nurse.
Very useful and sensible post.
Think of all the things you touch every day without thinking about it - door handles/knobs; a pen or pencil handed to you to sign something; elevator buttons; handrails on stairs, escalator, or bus; the receipt handed to you in a store when you purchase something, or the bar of the shopping cart you used in that same store.
It goes on and on ad infinitum.
Makes good sense to wash our hands - a LOT. We are probably more likely to contract something by transferring it from hands to face, than by catching it through the air from a cough or sneeze.
