PCV2 was first detected and described in pigs where it is widely distributed. PCV2-specific antibodies have been demonstrated in domestic pigs (Allan and Ellis, 2000) in most countries and most continents. PCV2 was associated with PMWS in 6-week-old wild boar piglets raised under free-range conditions (Ellis et al., 2003). Similarly, PMWS was observed in a 10-month-old male European wild boar in Germany (Schulze et al., 2004), and in a 6-month-old Spanish wild boar (Vicente et al., 2004).
