As these were the first pigs ever found to
harbor the virus, this obviously raises the possibility that they infected humans and played a role in the origin of the outbreak.
One possibility would be to find herds where only some of the animals have antibodies; within these groups, the ones that have not yet developed an immune defense may
harbor the virus, Koopmans says.
