In September 2024, bluetongue virus serotype 3 (BTV-3) was first identified in Portugal, specifically in the Alentejo region (Évora District), using molecular diagnostic methods. The initial case involved a sheep exhibiting severe clinical symptoms, including head oedema, prostration, nasal discharge, and significant respiratory distress. A subsequent case was documented in another sheep from a different farm within the same district, which presented with high fever (41.5 °C), nasal discharge, and arthritis, ultimately resulting in mortality. Within one month of these initial detections, additional cases in both sheep and cattle were reported in neighbouring districts, indicating the virus rapid spread within the region. In response to this emerging threat, extensive monitoring efforts are being undertaken to delineate the distribution of BTV-3, and vaccination campaigns targeting this serotype have been initiated. These measures aim to mitigate the impact of the virus on livestock health and prevent further transmission.
2024年9月，利用分子诊断方法在葡萄牙首次发现了蓝舌病病毒3型（BTV-3），具体是在阿连特茹地区（埃武拉区）。首例病例是一只出现严重临床症状的绵羊，包括头部水肿、虚脱、流鼻涕和严重呼吸窘迫。随后，在同一地区另一个农场的另一只绵羊身上记录到了病例，该绵羊出现高烧（41.5摄氏度）、流鼻涕和关节炎，最终死亡。在这些最初检测到病例后的一个月内，邻近地区报告了绵羊和牛的更多病例，表明该病毒在该地区迅速传播。针对这一新兴威胁，正在进行广泛监测以确定BTV-3的分布情况，并已启动针对该血清型的疫苗接种运动。这些措施旨在减轻病毒对牲畜健康的影响并防止进一步传播。
