American
veterinarians are effectively blaming Europeans for Porcine Circovirus in the USA
Anyway, they say, correctly, that is was in Europe in the
“late 1990s”
It was in Britain, in Northern Ireland,
Cornwall or East Anglia in 1998 or 1999. It may have been elsewhere. It certainly went everywhere else and is still a massive problem.
Certainly, the only British testing station for live pigs, in Northern Ireland, was closed down because of circovirus contamination, but live exports of pigs from Britain continued unhindered.
Much contemporaneous information on the origins of Porcine Circovirus in Britain has been preserved and is now only available on the newsgroup, uk.business.agriculture. Much has been removed from the WWW.
This will become the biggest scandal of the 21st century so far, with links to many other animal epidemics and the rise of antibiotic resistance. It also seems to be the key to the massive 2001 British Foot and Mouth epidemic.
How the hell a scientifically illiterate retired ship-broker with a bad heart and pancreatic cancer (now in remission) got there first, years ago, needs investigation. Who was asleep?
That should not happen. That really should not happen.
Circovirus Calls for
Flexible Approach

vaccinating mature sows for PCV2.

In the late 1990s, European animal health officials
identified a condition in swine that caused a chronic wasting syndrome in
nursery pigs. However, not until the mid-2000s did a syndrome become recognized
in the United States that included high mortality and morbidity in late nursery
to finishing swine.
The syndrome was originally coined postweaning multi-systemic wasting syndrome (PMWS). It was thought to be caused by everything from mycotoxins to virus. Later, it was learned the cause was porcine circovirus type 2 (PCV2).
Early on, PCV2 commonly produced
20-40% pig mortality. The pigs that survived performed very well despite the
lack of commercial vaccines...
