A virus is a small, infectious molecule made of genetic material wrapped up in a protein shell.  A bacteria is a microscopic single-cell organism.  The differences are most easily described with an analogy.  Suppose a virus is a person and a bacteria is a particle.  A virus can’t do anything on its own, it needs a host cell to provide it with a way to replicate and move around.  A bacteria can live independently, but it’s much more efficient if it uses a host cell’s cellular machinery for some of its own work, instead of replicating all of its proteins separately.

Do they spread the same ways, and if so, can you list examples of how they spread?
