AB  - OBJECTIVE: The present study is intended to show the progress of voluntary 
      porcine reproductive and respiratory syndrome (PRRS) control programmes in 
      Thuringia and Saxony as well as to emphasize the importance of confirmation 
      testing in the case of positive findings in unsuspicious herds. MATERIAL AND 
      METHODS: In order to present the progress of porcine reproductive and respiratory 
      syndrome virus (PRRSV) elimination, the findings for the years 2011-2018 as well 
      as data on the elimination programme, type and size of the farms, and use of PRRS 
      vaccination were compiled. Each herd was assigned an antibody and PCR status for 
      each year in order to analyze the relationship between status and year. 
      Furthermore, the association between status and herd size as well as the use of 
      PRRS vaccination were investigated. The relevance of confirmation testing is 
      shown by the findings of the herds in the years following PRRSV elimination. 
      RESULTS: In the majority of affected farms in Saxony, depopulation/repopulation 
      was performed in order to eliminate PRRSV. In Thuringia, PRRSV elimination was 
      frequently accomplished during ongoing production. A significant reduction of 
      positive antibody and PCR findings was observed in both federal states during the 
      investigation period. Higher antibody and PCR levels were evident in farms using 
      PRRS vaccination. In the years following PRRSV elimination, positive PRRSV 
      antibody findings occurred in individual PRRSV-unsuspicious farms. These were 
      shown to be false-positive by use of confirmation tests. CONCLUSIONS: The 
      proportion of PRRSV-positive herds in a region with low pig density can be 
      reduced by voluntary control programmes with the eradication method playing a 
      subordinate role. The use of vaccination against PRRSV or alternative control 
      measures is to be considered carefully. In the case of positive findings in 
      unsuspicious farms, confirmation testing is warranted in order to rule out any 
      ongoing PRRS outbreak as well as to clarify the farm's status. CLINICAL 
      RELEVANCE: Voluntary PRRS elimination and maintenance of the status of "PRRSV 
      unsuspicious" is possible even when individual herds in the region do not 
      participate in the control programme.
