PROTECT YOURSELF: ASSUME YOUR ENVIRONMENT IS CONTAMINATED
Responsible people, those who understand the Chain of Infection, using touch resonance contaminated fingers will not touch anything until they are washed clean. However, we cannot assume that every person that uses public utilities are so hygienic.
Conversely, we can safely assume that each time we use a public utility, others will have contaminated shared surfaces.
BREAKING THE CHAIN: PRIMARY METHODS
DISINFECTION WITH ALCOHOL
Virus particles are not alive - when out in the environment they are quite fragile. They soon wither, dry up and are no longer infectious.
It is not known how long COVID-19 lasts fresh, but is likely to be from 2 hours to 3 days: survival rates differ for various surfaces. [1][2] It is therefore wise to assume virus particles are active, and to assist the drying out process with 70% (or greater) alcohol.
Common methylated spirits is an example, but methanol can dry skin excessively if used frequently. Commercial sprays, wipes, and gels are commonly available. Alcohol gels are appropriate for hand usage, but not always for disinfecting shared surfaces. One should carry a small spray bottle at all times to spray appropriately (not indiscriminately).
"TOUCH RESONANCE" OR "HAPTIC MEMORY"
Do a little experiment on yourself. Pinch the back of one hand with the other. Notice when you let go, the pinched bit "remembers" the experience for quite some time. This is called touch resonance or haptic memory. The sensation may last for 30 seconds or longer if one focuses.
When you touch a potentially contaminated surface, focus on that touch resonance until, with the other hand, you have sprayed the area with disinfecting alcohol.
BARRIERS
It is best to avoid touching frequently shared utilities and surfaces. If surfaces must be touched (eg ATM buttons), barriers such as paper tissues should be used to avoid your own skin becoming vectored.
Barrier use is appropriate for respiratory viruses - the most common of which is the tissue into which one sneezes or coughs. Tissue barriers should not be re-pocketed (old style handkerchiefs can be dangerous vectors) but should appropriately discarded, and the hands then washed or disinfected.
Disposable gloves can act as barriers... but all too often they become the initiating vectors of a chain of vectors, so why bother? The Policeman wearing gloves, jotting things on a pad with a pen comes to mind; how is the pen sterilised? Both the pen and the gloves continue to be vectors & further contaminate every surface they touch.
It is how barriers are used that is important: not that they are simply out on display being "used".
