What does an active virus destroy a cell?

An active virus does not destroy a cell. Instead, it hijacks the cell's machinery to replicate and produce more virus particles, effectively compromising and manipulating the cell's normal functions for its own benefit. Once the virus finishes replicating, it usually exits the cell, possibly causing the cell to burst and release the newly formed viruses into the environment. Depending on the type of virus and the host cell, the infected cell may undergo various effects, including but not limited to cell death, altered metabolism, or dysfunction.
