Recently, eradication of PRRS has been demonstrated to be possible on an individual farm basis. Methods such as whole herd depopulation-repopulation, test and removal, and herd closure have been documented as effective methods for eliminating PRRS virus from endemically infected herds. Unfortunately, a number of eradication efforts have failed due to the introduction of new isolates through unidentifiable routes. | Recently, eradication of PRRS has been demonstrated to be possible on an individual farm basis.
