Distribution === Redondovirus genomes have been reported primarily from human samples surveyed using metagenomic DNA sequencing. They have been found primarily in oral and airway specimens. Disease associations It is unknown whether redondoviruses cause human disease. Some CRESS viruses are known pathogens, such as porcine circovirus type 2 Redondoviruses have been reported associated with periodontitis. In one study, the levels fell with successful treatment. Abundance of redondovirus genomes has also been found to be high in some intensive care unit patients. At present the basis of these disease associations is unclear.
