Reply to comment by -Metacelsus- in Are there any known endogenous retroviruses that can cause active infections, and is this possible in principle? by amlyo

Can't we argue that by definition a live virus should have a reproduction number strictly greater than 1 (ie. exponential) and be able to spread from cells to cells? For PERV-A seems they obtain exponential replication in human 293T cells https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2950858/figure/pone-0013203-g001/
