Explanation:
For coronavirus, it spreads when a person with coronavirus coughs, sneezes, get his or her saliva on another person, or when they get discharge from their nose on another person. I also know that if an infected person infects a non living object, the next person that touches it can get coronavirus by touching his or her body part. (Basically any where with holes including eyes, nose, mouth etc.) coronavirus can stay on surfaces for a long time. I don’t know how long though.
They are better because they are for comparative use for instance hair color to finger nails they both grow but onto separate parts of the body.
Hope this Helps [:
