Dr. Tom Burkgren-American Association of Swine Veterinarians:
We haven't seen any major changes in the way the virus is popping up.
It's still kind of sporadic.
Of course it's more likely to occur in an area that is hog dense and pretty much where you've expected to see it in the past you will expect to see it in the future.
The one interesting case is that we have seen a PED outbreak in Hawaii.
There's information being gathered about that trying to pinpoint the source of the PED, how it got into those pigs.
From what we've seen with the virus the previous year is that the cold weather allows the virus to spread a little bit easier.
The cooler weather is a more amenable for spread of the virus and the other thing that happens is it's a little bit harder in the mid-west when the temperature is 10 degrees above zero fahrenheit to wash and disinfect and dry down trailers especially the trailers being used for finisher transport.
We know that transport is a major risk factor for bringing the virus back to a farm.
So it's a complication, a risk factor that we've just got to be a little bit more aware of as you bring those trailers and trucks back to farms.
Dr. Burkgren says the more we pay attention to the details of biosecurity the more successful we'll be with any pathogen.
