AB  - Four years after the report of its discovery, porcine reproductive and 
      respiratory syndrome virus (PRRSV) continues to challenge swine producers, 
      veterinary practitioners, and animal health researchers in the United States. The 
      prevalence of infection is high--60% to 80% of herds is a reasonable 
      estimate--but the clinical effects of infection vary widely among farms. In many 
      herds, infection is unapparent and productivity seemingly unaffected. Some 
      infected herds report occasional respiratory disease outbreaks in young pigs, or 
      periodic outbreaks of reproductive disease, and a few herds experience severe, 
      chronic disease problems, particularly in young pigs. In these herds, secondary 
      infections with viral or bacterial pathogens, particularly Salmonella 
      choleraesuis, Streptococcus suis, or Haemophilus parasuis typically occur 
      concurrently with PRRSV infections. Understanding why some herds undergo 
      devastating episodes of clinical disease and others show no apparent effects is 
      central to solving the problem of clinical PRRS for swine producers. 
      Understanding the ecology and epidemiology of PRRSV is the key to preventing and 
      controlling PRRSV in the future. The objective of this article is to review 
      recent developments in these areas.
