AB  - Airborne transmission of porcine reproductive and respiratory syndrome virus 
      (PRRSV) is a risk factor for the infection of susceptible populations. Therefore, 
      a long‑term sustainability study of air filtration as a means to reduce this risk 
      was conducted. Participating herds (n = 38) were organized into 4 independent 
      cohorts and the effect of air filtration on the occurrence of new PRRSV 
      infections was analyzed at 3 different levels from September 2008 to January 2012 
      including the likelihood of infection in contemporary filtered and non-filtered 
      herds, the likelihood of infection before and after implementation of filtration 
      and the time to failure in filtered and non-filtered herds. Results indicated 
      that new PRRSV infections in filtered breeding herds were significantly lower 
      than in contemporary non-filtered control herds (P < 0.01), the odds for a new 
      PRRSV infection in breeding herds before filtration was 7.97 times higher than 
      the odds after filtration was initiated (P < 0.01) and the median time to new 
      PRRSV infections in filtered breeding herds of 30 months was significantly longer 
      than the 11 months observed in non-filtered herds (P < 0.01). In conclusion, 
      across all 3 levels of analysis, the long-term effect of air filtration on 
      reducing the occurrence of new PRRSV infections in the study population was 
      demonstrated.
