本文描述了猪繁殖与呼吸综合征(PRRS)的流行病学特点，即其在猪群中的“行为”，并将其与传染病的一般流行病学特征进行了比较。这一分析表明，感染PRRS病毒在流行病学上既是一种流行病，也是一种地方病：一方面，它可以像流行病一样在幼稚人群中传播，另一方面，它似乎在受影响的人群中无限存在，其临床表现像地方病一样，在不同的农场有不同的表现。本文试图就控制和/或根除这种疾病的一般方法得出“流行病学”结论，并确定进一步研究的领域。
The paper describes the specifics of the epidemiology of the Porcine Reproductive and Respiratory Syndrome (PRRS), that is its "behavior" as a communicable disease in porcine populations, and compares them to the general epidemiological characteristics of communicable diseases. This analysis shows that infection with the PRRS virus "behaves" epidemiologically both as an epidemic and as an endemic disease: on the one hand it can spread like an epidemic in naive populations, and on the other it seems to linger on infinitely in an affected population with its clinical expression varying from farm to farm like an endemic disease. The paper tries to draw "epidemiological" conclusions on the general methods for controlling and/or eradicating the disease, and to identify areas of further research.
