Step 2: Learn that viruses cannot reproduce on their own. They do not have the necessary tools or machinery to make copies of themselves.
Step 3: Realize that viruses need to invade a host cell. They attach to a host cell and use the cell's machinery to make more viruses.
Step 4: Conclude that a key characteristic of viral infections is that viruses require host cells to replicate.
