==Transmission==

CAV-1 infection occurs by inhalation and ingestion, after shedding in the urine, faecs or respiratory secretions. Transmission my be by direct contact, or by indirect contact and fomites such as handlers or infected surfaces. Following infection, the virus initially replicates in the tonsils and Peyer's patches. A viraemia is produced, and CAV-1 secondarily localises and replicates in the liver and kidneys.
