估算美国猪生产者每年因猪繁殖与呼吸综合征（PRRS）病毒感染而产生的成本。设计-经济分析样本群体-从美国中西部猪场的便利样本中收集PRRS影响和PRRS未影响的种猪群和生长猪群体的健康和生产力数据，分析PRRS影响和PRRS未影响猪场的程序-健康和生产力变量，以估计PRRS对特定猪场的影响。PRRS发病率的国家估计，然后用于确定每年的经济影响PRRS对美国猪producers.Results-PRRS影响的繁殖牛群和生长猪种群的测量减少生殖健康，增加死亡，并减少增长的速度和效率。这些影响对美国生猪生产商的年度经济影响估计为66.75美元。结论和临床相关性-PRRS给美国猪生产者带来了巨大的经济负担，每年造成约5.6032亿美元的损失。相比之下，在消灭之前，由于猪瘟（猪瘟）和伪狂犬病造成的年度损失估计分别为3.6409亿美元和3 627万美元（根据2004年美元调整）。目前的PRRS控制战略无法预测成功;因此，PRRS相关损失将持续到未来。有必要开展研究，以提高我们对PRRS病毒的生态学和流行病学特征的认识，并提高预防临床效应的技术（疫苗和诊断试验）。
Objective-To estimate the annual cost of infections attributable to porcine reproductive and respiratory syndrome (PRRS) virus to US swine producers. Design-Economic analysis.Sample Population-Data on the health and productivity of PRBS-affected and PRRS-unaffected breeding herds and growing-pig populations were collected from a convenience sample of swine farms in the midwestern United States.Procedure-Health and productivity variables of PBRS-affected and PRRS-unaffected swine farms were analyzed to estimate the impact of PRRS on specific farms. National estimates of PRRS incidence were then used to determine the annual economic impact of PRRS on US swine producers.Results-PRRS affected breeding herds and growing-pig populations as measured by a decrease in reproductive health, an increase in deaths, and reductions in the rate and efficiency of growth. Total annual economic impact of these effects on US swine producers was estimated at $66.75. million in breeding herds and $493.57 million in growing-pig populations.Conclusions and Clinical Relevance-PRRS imposes a substantial financial burden on US swine producers and causes approximately $560.32 million in losses each year. By comparison, prior to eradication, annual losses attributable to classical swine fever (hog cholera) and pseudorabies were estimated at $364.09 million and $36.27 million, respectively (adjusted on the basis of year 2004 dollars). Current PRRS control strategies are not predictably successful; thus, PRRS-associated losses will continue into the future. Research to improve our understanding of ecologic and epidemiologic characteristics of the PRRS virus and technologic advances (vaccines and diagnostic tests) to prevent clinical effects are warranted.
