Systematic Veterinary Virology

CONTROL

• Vaccination: Vaccines containing live attenuated CPV generally induce more effective immunity than inactivated virus vaccines. The high-titer CPV vaccines now available effectively protect puppies against viral challenge, even during the period when maternal antibody titers remain high enough to interfere with active immunization but have declined enough to predispose pups to infection. Three doses of vaccine are recommended at 6, 9, and 12 wk of age.
• Eradication: To eradicate CPV following points should be observed.
• Isolation of affected dogs from other dogs.
• Canine parvovirus can survive for weeks in contaminated cages and kennels, and thorough disinfection (e.g., sodium hypochlorite solution) is necessary before uninfected dogs are admitted.
• Disinfection of hands, clothing, and food and water bowls is recommended.
• Pups should be kept isolated from adult dogs returning from shows or field trials
