Porcine reproductive and respiratory syndrome (PRRS) is characterized by reproductive failure in sows and respiratory problems in growing pigs. The disease is present in most countries throughout the world but was not diagnosed in Sweden until the summer of 2007 when it was first detected through the national PRRS surveillance program. The immediate mobilization of veterinary authorities, field veterinarians and the pig industry was a prerequisite for preventing the spread of the disease. Within 10 days seven herds were verified as infected and the measures taken included stamping out, cleaning, disinfection and a vacancy period of 3 weeks before the herds were repopulated. To evaluate the effectiveness of these measures, a national sero-surveillance was carried out during the autumn of 2007. Approximately 90% of the pig production was covered by this screening and all samples tested were negative with regard to antibodies to PRRS virus.
猪繁殖与呼吸综合征(PRRS)的特征是母猪繁殖失败以及生长猪出现呼吸问题。该疾病在世界上大多数国家都有存在,但直到2007年夏天才在瑞典被诊断出来,当时它是通过国家PRRS监测计划首次被发现的。兽医当局、现场兽医和养猪业的立即动员是防止疾病传播的先决条件。在10天内,有7个猪群被证实感染,采取的措施包括扑杀、清洁、消毒以及在猪群重新补栏前有3周的空栏期。为了评估这些措施的有效性,在2007年秋季进行了一次全国血清监测。这次筛查覆盖了大约90%的生猪生产,并且所有检测的样本在PRRS病毒抗体方面均为阴性。
