Ans: Viruses need a host cell to replicate and a bacteria needs food to continue to replicate. B. What can anti-viral drugs target in order to bring a viral infection under control, or to prevent a viral infection in the first place?

What can anti-viral drugs target to prevent a viral infection in the first place? Ans: To prevent a viral infection in the first place you could take a medication that would alter the surface receptor, fill in the surface receptor or inhibits the viral surface protein all together.
