Instead, they must invade a host organism and hijack its genetic instructions.

What is required for a virus to reproduce?

Viruses are tiny infectious agents that rely on living cells to multiply. They may use an animal, plant, or bacteria host to survive and reproduce. As such, there is some debate as to whether or not viruses should be considered living organisms. A virus that is outside of a host cell is known as a virion.
