Harding provides a look into the history of PCVD and PMWS diagnosis, including pathology and history of outbreaks. Today it is estimated that PCVD is present in 14% of finisher and farrow-to-finish operations in the 3 Western Canadian provinces. Common signs include wasting, pallor, diarrhoea, and laboured breathing. There are 2 vaccinations available at the time of writing and 2 more awaiting registration. PCV2 vaccinations are administered in the breeding herd in order to improve colostral immunity passage to piglets.
