Viruses are tiny infectious agents made up of genetic material (DNA or RNA) and surrounded by a protein coating called a capsid. They are not bacteria and do not respond to antibodies in the bloodstream. While some viruses can enter the body through the skin or bloodstream, they are not considered genetic mutations themselves.
