How do viruses spread?

How do viruses spread? Once a person is infected with a virus, their body becomes a reservoir of virus particles which can be released in bodily fluids – such as by coughing and sneezing – or by shedding skin or in some cases even touching surfaces. The virus particles may then either end up on a new potential host or an inanimate object.
