In chronic viral infection, in contrast, viral replication and infectious particle production are continually maintained. For many such infections, recurrent episodes of high viral production and release interrupt relatively long periods of low-level viral replication.
Why are viruses not considered alive?
Are viruses alive or dead? 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.
Where did viruses evolve from?
Viruses may have arisen from mobile genetic elements that gained the ability to move between cells. They may be descendants of previously free-living organisms that adapted a parasitic replication strategy. Perhaps viruses existed before, and led to the evolution of, cellular life.
