To this end, 621 references were analyzed. It is evident that the number of publications increased between 2010 and 2020, which emphasizes the importance of the subject.

As the farmer discontinued sow vaccination and just partly increased biosecurity, this may have contributed to ongoing virus circulation and clinical signs in pigs, even 5 months post-diagnosis.
