Prevention of feline herpesvirus, feline calicivirus, and Chlamydia can be enhanced greatly by the proper use of vaccinations against these diseases. Immunization offers protection from clinical signs of disease but not infection. Therefore, even well-vaccinated cats can be chronic carriers of a virus.
For prevention of the diseases in groups of cats, additional control measures are recommended. Routine vaccinations should be performed on all cats, and new cats should be vaccinated and isolated for three weeks. In addition, owners should maintain thorough hygiene techniques, avoid overcrowding, and isolate suspected carriers from the rest of the population.
