The following was received from an assistant professor in infectious diseases at Johns Hopkins University and is very informative. It is an excellent summary to avoid contagion and I share it with your readers because it is very clear:
• The virus is not a living organism, but a protein molecule (DNA) covered by a protective layer of lipid (fat) which, when absorbed by the cells of the ocular, nasal or buccal mucosa, changes their genetic code (mutation) and convert them into aggressor and multiplier cells.
• Since the virus is not a living organism but a protein molecule, it is not killed, but decays on its own. The disintegration time depends on the temperature, humidity and the type of material where it lies.
• The virus is very fragile; the only thing that protects it is a thin outer layer of fat. That is why any soap or detergent is the best remedy, because the foam cuts the fat. That is why you have to rub so much: for 20 seconds or more, to make a lot of foam. By dissolving the fat layer, the protein molecule disperses and breaks down on its own.
• Heat melts fat, which is why it is so good to use water above 25 degrees Celsius for washing hands, clothes and everything. In addition, hot water makes more foam and that makes it even more useful.
• Alcohol or any mixture with alcohol over 65% dissolves any fat, especially the external lipid layer of the virus.
• Any mix with one part bleach and five parts water directly dissolves the protein, breaking it down from the inside.
• Oxygenated water helps long after soap, alcohol and chlorine, because peroxide dissolves the virus protein - but you have to use it pure, and this hurts your skin.
• No bactericide serves any purpose. The virus is not a living organism like bacteria; one cannot kill that which is not alive with antibiotics, but its structure can quickly be disintegrated with everything mentioned here.
• Never shake used or unused clothing, sheets or cloth. While the virus is glued to a porous surface, it is very inert and disintegrates only within three hours (fabric and porous surfaces) or four hours (copper, because it is naturally antiseptic; and wood, because it removes all the moisture and does not let it peel off and disintegrate).
It can live for 24 hours on cardboard, 42 hours on metal and 72 hours on plastic. But if you shake it or use a feather duster, the virus molecules float in the air for up to three hours, and can lodge in your nose.
• The virus molecules remain very stable in external cold, or artificial as air conditioners in houses and cars. They also need moisture to stay stable, and especially darkness. Therefore, dehumidified, dry, warm and bright environments will degrade it faster.
• UV light on any object that may contain it breaks down the virus protein. For example, it is perfect to disinfect and reuse a mask. Be careful, though, as it also breaks down collagen (which is protein) in the skin, eventually causing wrinkles and skin cancer.
• The virus cannot go through healthy skin.
• Vinegar is not useful because it does not break down the protective layer of fat.
• No spirits, for example vodka, will serve in breaking it down. The strongest vodka is 40% alcohol, and you need 65%.
• Listerine will do as it contains 65% alcohol.
• The more confined the space, the more concentrated the virus will be; the more open or naturally ventilated, the less.
• This can’t be said enough: you have to wash your hands before and after touching mucosa, food, locks, knobs, switches, remote controls, cell phones, watches, computers, desks, TVs, etc. And of course when using the bathroom.
• You have to humidify hands dried out from so much washing, because the molecules can hide in the micro cracks. The thicker the moisturiser, the better. Also, keep your nails short so that the virus does not hide there.
