Are viruses living?
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Effects on the host cell Most virus infections eventually result in the death of the host cell. The causes of death include cell lysis (bursting), alterations to the cell’s surface membrane and apoptosis (cell “suicide”).
Do viruses have any purpose?
These latent viruses might sometimes be beneficial, as the presence of the virus can increase immunity against bacterial pathogens, such as Yersinia pestis. Some viruses can cause lifelong or chronic infections, where the viruses continue to replicate in the body despite the host’s defence mechanisms.
