Interpretive Summary:

Technical Abstract: In this report we review the historical aspects and describe several other facets of a disease that is commonly referred to as atypical porcine reproductive and respiratory syndrome (PRRS). Topics covered include early efforts to name the disease and to determine its cause as well as its incidence and geographic distribution. We also discuss some of our current in vitro and in vivo studies to define the circumstances that dictate the appearance and contribute to the distinguishing features of atypical PRRS -- which with our current state of knowledge appears to be simply a more severe clinical form of a costly disease, namely, PRRS, or as a point of contrast typical PRRS, that first appeared in this country in 1987. Sharing such information will contribute to the eventual control of both typical and atypical PRRS and thus result in a substantial saving for the swine industries worldwide.
