Technical Abstract: This information comprises a section on diagnosis in a chapter on porcine reproductive and respiratory syndrome virus (PRRSV) for the 8th edition of the book titled "Diseases of Swine," ISU Press, Ames, Iowa. A diagnosis of PRRS is based on a combination of herd history, production records analysis, clinical signs, gross lesions, microscopic lesions, serology, and virus detection. PRRS should be considered when there are clinical signs of respiratory disease occurring at any stage of production, when reproductive failure occurs, and when herd performance is suboptimal. Mild or subclinical disease is common, so absence of clinical signs does not ensure a porcine reproductive and respiratory syndrome virus (PRRSv) free herd.
