Retroviruses integrate the DNA produced by reverse transcription into the host genome as a provirus as a part of the replication process; pararetroviruses do not, although integrated genome copies of especially Latent infections, which may not cause symptoms at first but can reactivate over a period of months and years. However, at some point, the provirus or prophage may give rise to active virus, which may lyse the host cells.
