Porcine Circovirus Type 2: Genotypes and protection, where do we stand?

Of the 8 existing genotypes, only PCV2 a, b and d have a  global distribution (Franzo et al. 2018); of these three,  PCV2b is the one most isolated in Europe and the Americas.  In turn, PCV2d was particularly relevant in Asia, where its  isolation was greater than that of PCV2b.
