Influenza is caused by a lytic virus while Hepatitis C is caused by a non-lytic virus.
Explanation:
The lytic cycle for reproduction enables the virus to make several copies of itself and destroys the host cell in the process. Many bacteriophages (viruses that infect bacteria) adhere to the lytic cycle. During the lytic cycle, once the virus has attached itself to the host cell, it injects its DNA into it. The virus is thus able to use the host cell's machinery to synthesize proteins and replicate itself.
