Introduction
Vaccination against porcine circovirus type 2 (PCV2) reduces the incidence and severity of porcine circoviral disease (PCVD), in particular the postweaning multisystemic wasting syndrome (PMWS). This confirms that PCV2 is the essential infectious agent in this disease syndrome, but attempts to elucidate why PMWS became an emerging disease have failed. Much still remain to be clarified regarding the epidemiology of PCV2, its interaction with the host and the role of other infections in the development of PCVD. The current views on these issues are summarized below.
