Question

explain how virus can be spread​

Answer 1

ǟռֆաɛʀ :

Viruses spread from person to person mainly in droplets that fly out when you cough or sneeze. These tiny drops from a sick person move through the air and land on the mouths or noses of others nearby.

Germs are also passed along when you touch mucus droplets from someone else on a surface like a desk and then touch your own eyes, mouth, or nose before you get a chance to wash your hands. Viruses like the flu can live 24 hours or longer on plastic and metal surfaces like cafeteria tables, doorknobs, and cups.

Viruses spread from person to person mainly through the tiny droplets that are produced when a person carrying the virus coughs or sneezes. Those droplets, whether we can see them or not, may fly and land on a surface. Some may land directly on the mouth, nose or eye of another person while others may land on a hard surface like a phone, doorknob or countertop. How long those particles survive on the surface varies depending on both the surface and the viral strand. For some viruses it is only a few hours; for others it can be as much as nine days. If a healthy person touches one of those surfaces and then touches their nose, mouth or eyes before washing their hands, they have transmitted the virus to themselves. If that person now carrying the virus coughs or sneezes and doesn’t disinfect the area, the virus can be transmitted again, and the cycle continues.
