FCV is endemic worldwide. Transmission occurs through '''direct contact''' with secretions of carrier cats or '''indirect contact''' via drinking bowls, etc. Clinical disease is most frequently seen in kittens; '''active immunity''' is generally present in animals over 1 year of age. Antigenic variation means that subclinical reinfections can occur. | FCV is endemic worldwide.
