it might. the herpes simplex virus replicates via the lysogenic cycle, i. e. in inserts itself unspecifically into the host cells genome via non-homologous end joining (NHEJ). Cellular and/or environmental triggers lead to the excision of this (now) latent virus, which can carry adjacent DNA segments along under certain circumstances. If the new overall DNA sequence doesn’t surpass a critical size, have a disrupted reading frame, etc., it can still be packaged into infectious virus particles during the lytic cycle and then be inserted into new (foreign) host cells. This is also a major contribution to the evolution of viruses. Genetics is a huge discipline, if you want to know more, I should’ve given you enough key words for your googling.
