Par·vo·vi·rus (pahrґvo-vi″rəs) [parvo- + virus] parvoviruses; a genus of viruses of the subfamily Parvovirinae (family Parvoviridae) that infect mammals and birds.

Human parvoviruses cause transient aplastic crisis, acute arthritis, erythema infectiosum, hydrops fetalis, spontaneous abortion, and fetal death. Animal pathogens include bovine, canine, feline, and goose parvoviruses, feline panleukopenia virus, mink enteritis virus, Aleutian mink disease virus, and various murine parvoviruses.
