I'm not sure exactly what you are asking, but:
- When people exhale, cough, or sneeze, the virus comes out in droplets that can remain in the air for up to ten minutes and travel up to 20 feet.
- Then the droplets fall in surfaces and can last for up to several days, where they can be touched and picked up by fingers, which then infect a person when the fingers touch nose, mouth, or eyes.
- Humidity and warmth protect against viral transmission. Masks protect, both by preventing breathing of aerosol viruses and preventing touching of nose or mouth. Washing hands with hot water and soap, or alcohol, protects.
- Drinking water protects, as viruses are digested and destroyed if swallowed. They have to reach the lungs.
- Once in the lungs they enter cells via the ACE2 receptor on epithelial cells and replicate. The inflammatory response to the viruses can cause the air sacs of the lung to fill up with fluid and mucus, causing suffocation. That is why in severe cases you need oxygen, to make up for the loss of lung capacity.
