Schmallenberg virus (SBV) circulation was investigated in 25 previously exposed dairy herds in Ireland in 2016. A population of 1,550 spring-2014-born animals, which had been monitored for SBV infection in 2014 and 2015 as part of a previous SBV surveillance study, were resampled for evidence of SBV infection during 2016. A total of 366 blood samples were collected in the 25 study herds (15 samples per herd) between 3 March 2017 and 10 March 2017 (before the 2017 vector-active season) and analysed for SBV antibodies using a competitive ELISA kit (IDVet). A total of 256 animals tested seropositive, an AP of 69.9% (95% CI: 65.1-74.4) and TP of 77.7% (95% CI: 72.3%-82.8%) when correcting for imperfect test characteristics. These results demonstrate that a new epidemic of SBV circulation occurred in these previously exposed herds in Ireland in 2016.
2016年，在爱尔兰对25个之前已接触过的奶牛场进行了施马伦贝格病毒（SBV）传播情况调查。作为之前SBV监测研究的一部分，对2014年春季出生的1550头动物在2014年和2015年进行了SBV感染监测，2016年对这些动物再次采样以获取SBV感染证据。2017年3月3日至2017年3月10日（在2017年媒介活跃季节之前），在25个研究奶牛场共采集了366份血样（每个奶牛场15份），并使用竞争ELISA试剂盒（IDVet）分析SBV抗体。校正检测特性不完善的情况后，共有256头动物检测为血清阳性，表观流行率为69.9%（95%可信区间：65.1 - 74.4），真实流行率为77.7%（95%可信区间：72.3% - 82.8%）。这些结果表明，2016年在爱尔兰这些之前已接触过的奶牛场发生了SBV传播的新一轮疫情。
