PRSV doesn’t immediately kill the plant. It kills it slowly over quite some time. It replicates in the growing point of the plant. This conveniently is the same location where aphids feed.
The aphids then transfer the virus to a new plant. Plant viruses have a wide range of host species and they move around with their vectors.
For more information, Here is an excellent write up on the virus.
