Viruses are shed via urine, sexual fluids, and from external mucus, whereas kidney, spleen, and other internal organs are the sites where the virus is most abundant during the course of overt infection. Insects, annelids, and crustaceans may act as viral vectors.
In the context of overt infection, viruses tend to accumulate in urine, bodily fluids, and external mucus, whereas internal organs like kidneys and spleens become focal points for viral replication. Furthermore, insects, annelids, and crustaceans can facilitate the transmission of the virus.
