there are 3 entries for a virus. mouth, nose, and eyes
Your mouth has acids to neutralize most things.
Your nose has ‘filtration’ which will block most air particles.
But your eyes have nothing. The thinnest membrane and little to no protection.
This is how people normally get the flu.
by touching something infected (ie: surface) and then touching their face.
Best way to avoid contracting the virus would be to avoid touching your face when you’re out and to wash your hands regularly.
This being a formite bug, you have to include hand to ears, and also hand to genitals contact. The membranes on the downstairs are just as thin as the eyelids or inner lips of the mouth. The natural acids levels are not enough to distroy the lipid coat of SARS COVID II there is also a very real risk of sexual transmission of covid the ACE 2 receptors are all over the male genital track. How many people wash their hands BEFORE using the loo? You mine as well just lick your fingers its biological nearly identical to take your unwashed hands and contact your genital membranes. Think about that the next time you handle.stuff in tne store then run off for a quick loo break.
There are other entry points for viruses other than facial orifices.
You are not wearing masks to protect yourself from getting infected. You are wearing masks to protect others from getting what you have.
Hand washing is very important. I worked where we manufactured K-cups used in those coffee machines. We had to hand wash for 20 seconds before entering the production area and leaving the production area. There was a person there to monitor your handwashing. Get caught not doing it correctly and you were out the door. I cannot stress the importance of hand washing. It protects others from you contaminating them with what you have. It also illustrates the way we should approach hygiene safety.
