How do you thoroughly wash your hands one-handed to prevent coronavirus transmission?

There is no point in looking for your fucking failures of stroke associations to provide this. It is obvious the response is likely; 'Just fuck off and die'. Your doctor will be no help.  I need to know, going to Madagascar this week and Vienna and northern Italy in April if Italy borders aren't completely closed. We were planning on visiting Balzano, the area between the Lombardy and Veneto regions that are hard hit. I'm healthy and not concerned.

Damn, I had an excellent comment from Jo, but managed to delete it.  

Hand-washing: Do's and don'ts

We should have a protocol for one handed washing. Where is it?  I assume hand washing is an ADL.

Hand-washing is an easy way to prevent infection. Understand when to wash your hands, how to properly use hand sanitizer and how to get your children into the habit.By Mayo Clinic Staff

Frequent hand-washing is one of the best ways to avoid getting sick and spreading illness. Hand-washing requires only soap and water or an alcohol-based hand sanitizer — a cleanser that doesn't require water.
Find out when and how to wash your hands properly.

When to wash your hands

As you touch people, surfaces and objects throughout the day, you accumulate germs on your hands. In turn, you can infect yourself with these germs by touching your eyes, nose or mouth. Although it's impossible to keep your hands germ-free, washing your hands frequently can help limit the transfer of bacteria, viruses and other microbes.
Always wash your hands before:

• Preparing food or eating
• Treating wounds, giving medicine, or caring for a sick or injured person
• Inserting or removing contact lenses

Always wash your hands after:

• Preparing food, especially raw meat or poultry
• Using the toilet or changing a diaper
• Touching an animal or animal toys, leashes or waste
• Blowing your nose, coughing or sneezing into your hands
• Treating wounds or caring for a sick or injured person
• Handling garbage, household or garden chemicals, or anything that could be contaminated — such as a cleaning cloth or soiled shoes
• Shaking hands with others

In addition, wash your hands whenever they look dirty.

How to wash your hands

It's generally best to wash your hands with soap and water. Follow these simple steps:

• Wet your hands with running water — either warm or cold.
• Apply liquid, bar or powder soap.
• Lather well.
• Rub your hands vigorously for at least 20 seconds. Remember to scrub all surfaces, including the backs of your hands, wrists, between your fingers and under your fingernails.
• Rinse well.
• Dry your hands with a clean or disposable towel or air dryer.
• If possible, use a towel or your elbow to turn off the faucet.

Antibacterial soaps, such as those containing triclosan, are no more effective at killing germs than is regular soap. Using antibacterial soap might even lead to the development of bacteria that are resistant to the product's antimicrobial agents — making it harder to kill these germs in the future. In 2016 the Food and Drug Administration issued a rule under which over-the-counter consumer antiseptic wash products containing the majority of the antibacterial active ingredients — including triclosan and triclocarban — can no longer be marketed to consumers. These products include liquid, foam and gel hand soaps, bar soaps and body washes.
