How Viruses Spread and Work

Viruses mostly spread when droplets fly out of the mouth or nose when you sneeze or cough. The droplets would move through the air and would attach themselves to bodies and surfaces.

When a person is infected with a virus, they body becomes a pool of virus particles. The virus particles can be released when the person infected coughs or sneezes, in some cases, shedding skin and even touching surfaces.

Virus particles can either go into a new host or a non-living object.
