Viruses require what in order to grow?

Explanation:
Viruses can only reproduce inside living cells, using the host’s machinery to copy their genetic material and assemble new virus particles. Outside a host, a virus isn’t actively growing or replicating; it’s essentially dormant. That’s why a living host is essential for viral growth. Oxygen, direct sunlight, or moisture aren’t what enables a virus to multiply—viruses don’t run on their own metabolism, and sunlight can actually inactivate viruses, while moisture simply affects their survival rather than their ability to replicate. For example, influenza copies itself inside respiratory cells, not in the air or on surfaces.
