124 has been around and this lineage 1C though is a variant that's caused more problems and been much more pathogenic clinically out in the countryside than what we've had before.
PRRS 124 Line 1C has been especially hard in the Midwest, the pork production areas of the Midwest, Minnesota, Iowa, down into Missouri and even across to Nebraska and Illinois on the other side.
It's a regional issue that has been very difficult for practitioners to handle because it tends to stay on the farms longer and be harder to get rid of, be harder to step out of a farm and so our objective is to give people some practical information about how to handle those types of situations.
