On 22 August, a common whitethroat in the Netherlands tested positive for West Nile virus lineage 2. The same bird had tested negative in spring. Subsequent testing of mosquitoes collected in August and early September in the same location generated two of 44 positive mosquito pools, providing first evidence for enzootic transmission in the Netherlands. Sequences generated from the positive mosquito pools clustered with sequences that originate from Germany, Austria and the Czech Republic.
8 月 22 日,荷兰一只普通白喉莺检测出西尼罗河病毒 2 谱系阳性。该鸟在春季的检测结果为阴性。随后对同一地点 8 月和 9 月初采集的蚊子进行检测,有 44 个蚊子池中有 2 个呈阳性,这首次提供了荷兰蚊媒传播的证据。从阳性蚊子池生成的序列与源自德国、奥地利和捷克共和国的序列聚类。
