Detailed explanation-1: -Data has shown that the COVID-19 virus spreads mainly from person to person among those in close contact. The virus spreads by respiratory droplets released when someone with the virus coughs, sneezes, breathes, sings or talks. These droplets can be inhaled or land in the mouth, nose or eyes of a person nearby.

Detailed explanation-2: -The coronavirus latches its spiky surface proteins to receptors on healthy cells, especially those in your lungs. Specifically, the viral proteins bust into cells through ACE2 receptors. Once inside, the coronavirus hijacks healthy cells and takes command. Eventually, it kills some of the healthy cells.

Detailed explanation-3: -COVID-19 is caused by a virus called SARS-CoV-2. It is part of the coronavirus family, which include common viruses that cause a variety of diseases from head or chest colds to more severe (but more rare) diseases like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

Detailed explanation-4: -One similarity between bloodborne pathogens and SARS-CoV-2 is that they can both be transmitted via mucus membrane exposures to the eyes, nose, and/or mouth. Spit, vomit, sputum, or mucus can also contain blood – these body fluids are classified by OSHA as “other potentially infectious materials”.
