You mention hand sanitisers. How does that help then? I 'm not the bravest and most optimistic of people. I'll readily admit I'm scared .
Hand Sanitizers
The threat, the coronavirus, is generally transmitted through the air. It is transmitted between people two main ways. You are near someone who is infected, they sneeze or cough and small droplets which carry some of the coronavirus travels through the air. You breathe the air and become infected. Or the person coughs or sneezes and these small droplets land on an object. You touch the object and then touch your face and then become infected.
So in the first case, how far will these droplets travel in the air. The answer is less than 6 feet. So if you stay away 6 feet from an infected person, you are generally safe. But out in public you do not know who is infected and who is not. They do not exactly wear signs saying "I have the coronavirus". But if you shelter-in-place in your home or apartment, you are relatively safe. But most people find it difficult to do this. They need to work, to buy groceries, etc. So when you leave the safety of your home, you incur a risk of becoming infected. One way to provide some protection is using a proper face mask such as an N95 face mask that will filter out most of these coronavirus particles.

But what about the second route of transmission. Someone coughs or sneezes and the droplets land on objects that you subsequently touch. The general solution is to wash your hands with soap and water. But is that realistic?
If you wash with water for 20 seconds, the contamination is reduced around 77%.
If you wash with soap and water, the contamination level is reduced a total of around 92%.
But the problem here, is that most people touch their face around 500 times per day.
If I washed my hands every time I touched my face, I would probably spend my entire life at the bathroom sink.
This is where hand sanitizers come into play.

Hand sanitizing gel is an evaporating gel that kills 99.99% of the germs in 15 seconds. Rather than just trying to wash away the germs I am more focused on killing them (or deactivating them). Besides it is fairly inexpensive. I would recommend obtaining a large bottle and then a small size individual bottle that one can carry around in their pockets when they are on the go. When the small bottle is empty it can be refilled using the large bottle. It is probably a good routine to use this gel every time one gets the urge to touch their face out in public.
So soap and water is good, but soap and water and hand sanitizing gel is even better; much, much better.
But there is another wrinkle. Both N95 face mask and now even sanitizing gel have been flying off the shelves as people prepare for the threat of the coronavirus. They are quickly becoming OUT OF STOCK.
