Cyclovirus Explained

The viral genus Cyclovirus is a genus in the family Circoviridae. Viruses in this genus have been isolated from dragonflies,^[1] as well as chickens, goats, sheep, and other farm animals.^[2] Cycloviruses have also been found in the feces of healthy humans and chimpanzees^[3] and in samples of cerebrospinal fluid from patients with unexplained paraplegia.^[4]
