How do viruses move through the body?
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.

Viremia is a medical term for viruses present in the bloodstream. A virus is a tiny, microscopic organism made of genetic material inside a protein coating. Viruses depend on a living host, like a human or animal, for survival. They survive by invading cells and using those cells to multiply and produce other viruses.
