In Andalusia, Spain, West Nile virus (WNV) surveillance takes place from April to November, during the active vector period. Within this area seroconversion to this virus was evidenced in wild birds in 2004, affecting horses and two humans for the first time in 2010. Since 2010, the virus has been isolated every year in horses, and national and regional surveillance plans have been updated with the epidemiological changes found. WNV is spreading rapidly throughout southern Europe and has caused outbreaks in humans. Here we describe the second WNV outbreak in humans in Andalusia, with three confirmed cases, which occurred between August and September 2016, and the measures carried out to control it. Surveillance during the transmission season is essential to monitor and ensure prompt identification of any outbreaks.
在西班牙安达卢西亚地区，西尼罗河病毒（WNV）的监测工作从四月到十一月进行，正值活跃的媒介期。在该地区，2004 年有野生鸟类出现针对该病毒的血清转换，2010 年首次影响到马和两个人类。自 2010 年以来，每年都在马中分离到该病毒，并且随着发现的流行病学变化，国家和地区监测计划也得到了更新。WNV 在整个南欧迅速传播，并在人类中引发了疫情。在此，我们描述了 2016 年 8 月至 9 月期间安达卢西亚发生的第二起人类西尼罗河病毒疫情，有三例确诊病例，并介绍了为控制疫情而采取的措施。在传播季节进行监测对于监测和确保及时发现任何疫情至关重要。
