Control of Porcine Circovirus Disease (PCVD)

PCVD is a multifactorial disease where viruses, the environment and other factors all play a role in causing disease. For control to be effective, many factors must be taken into consideration. It has been determined that the presence of PCV-2 is essential for the development of the syndrome.

PCV-2 is very resistant to disinfectants and conventional inactivation methods making decontamination of premises difficult. Control measures therefore focus on preventing the co-factors involved in PCVD’s. See General Control Measures.

PCV-2 vaccines have shown to protect against the development of PCVD's. The use of these vaccines have resulted in the improvement of mortality rates after weaning and during fattening of pigs on farms affected by PCVD. See Vaccination.
