That's a lot of pigs. It becomes increasingly clear that the PEDv is not airborne.
The Americans correctly deduce that humans are the main vector of carriage.
There is too much traffic through the average pig farm of people going from farm to farm, everywhere
That's nothing new. During the Classical Swine Fever (CSF) and, Foot and Mouth (FMD) epidemics in Britain, government veterinarians were going from infected farms to clean ones and not always taking the appropriate precautions.
If you allow government veterinarians to edit or fake the data to remove them from any possibility of fault, you will never get to stop the national and international movement of animal and zoonotic disease.
The remedy is clear, supervise them and if you catch them: sack and prosecute.
If that had been the policy in Britain in 1999, intensive livestock farming would not be in the mess it is in now.
Government also needs to tackle the associated disinformation campaigns.
