Dr.Irene Ken of Johns Hopkins University in the United States gave her daughter 18 opinions on the COVID-19 virus:

1.Viruses is not living organisms, but protein molecules (DNA) covered by a protective layer of lipids (fat). When absorbed by cells in the mucous membranes of the eyes, nose or cheek, their genetic code changes (mutates) and turns them into attackers and multipliers.

2.Since the virus is not a living organism, but a protein molecule, it will not be killed, but will degrade by itself. The time to disintegrate depends on the temperature, humidity and the type of attached materials.

3.Viruses are very vulnerable; The only thing that protects it is the thin outer layer of fat. That's why any soap or cleanser is the best treatment, as the foam cuts the fat (which is why you have to rub your hands for 20 seconds or more to get a lot of foam). By dissolving the fat layer, the protein molecules disperse and break down.

4.Heat can melts fat; this is why it is best to use water above 25 degrees Celsius to wash hands, clothes and everything. In addition, hot water will make more foam, which makes the foam more useful.

5.Alcohol or any mixture with an alcohol content of more than 65% can dissolve fat, especially the outer lipid layer of the virus.

6.Any mixture containing 1:5 bleach and water will dissolve the protein directly and break it down from within.

7.Oxygenated water will work for a long time, because peroxide will dissolve viral proteins, but you must use pure oxygenated water, otherwise it will harm your skin.

8.Not sterilization. Viruses are not creatures like bacteria. Antibiotics cannot be used to kill inanimate things, but their structure can be quickly broken down by everything that is said.

9.Virus molecules are very stable in the cold outside or in the air conditioning of indoor and automobile conditions. They also need darkness and water to stay stable. So dehumidifying, drying, warm and bright environments will make it degrade more quickly.

10.Virus molecules are very stable in the cold outside or in the air conditioning of indoor and automobile conditions. They also need darkness and water to stay stable. So dehumidifying, drying, warm and bright environments will make it degrade more quickly.

11.Exposing ultraviolet rays to any object that can absorb ultraviolet rays will decompose viral proteins. For example, disinfecting reusable masks. Note that UV rays break down the collagen (protein) in the skin, eventually leading to wrinkles and skin cancer.

12.The virus cannot pass through healthy skin.

13.Vinegar doesn't work because it doesn't break the protective layer of fat

14.Drinking won't help, not even vodka. The strongest vodka is only 40% alcohol; you need 65% alcohol.

15.LISTERINE, (an antiseptic mouthwash), it contains 65% alcohol.

16.The narrower the space, the higher the concentration of virus, while the open or naturally ventilated space, the less virus.

17.You must wash your hands before and after touching mucous membranes, food, locks, knobs, switches, remote controls, mobile phones, watches, computers, desks, TVs, etc., and when using the bathroom.

18.You must wash your hands frequently and the thicker the moisturizer, the better. Also, keep your nails short so the virus can't hide inside.

Beside all above, one most effective way to fight the COVID-19 virus is vaccination. Today ,there are many kinds of vaccines around the worls. And Meling will give you our opinions on 2~8 ℃vaccine refrigerators ,-25 ℃ biomedical freezers or -40~-86℃ ULT freezers  for storing  vaccines based on the vaccine you use.
