In 2010, for the third consecutive year, human cases of West Nile virus (WNV) infection, including three confirmed cases of neuroinvasive disease and three confirmed cases of West Nile fever, were identified in north-eastern Italy. While in 2008 and 2009 all human cases of WNV disease were recorded in the south of the Veneto region, cases of WNV disease in 2010 additionally occurred in two relatively small northern areas of Veneto, located outside those with WNV circulation in the previous years. WNV IgG antibody prevalence in blood donors resident in Veneto was estimated as ranging from 3.2 per 1,000 in areas not affected by cases of WNV disease to 33.3 per 1,000 in a highly affected area of the Rovigo province. No further autochthonous human cases of WNV disease were notified in Italy in 2010. The recurrence of human cases of WNV infection for the third consecutive year strongly suggests WNV has become endemic in north-eastern Italy.
2010 年，意大利东北部连续第三年发现人类感染西尼罗河病毒（WNV）病例，包括三例确诊的神经侵袭性疾病和三例确诊的西尼罗河热病例。而在 2008 年和 2009 年，所有的 WNV 疾病人类病例都发生在威尼托地区的南部，2010 年的 WNV 疾病病例还发生在威尼托的两个相对较小的北部地区，这些地区在前几年没有 WNV 的传播。威尼托地区居民的血液供体中WNV IgG 抗体的流行率估计范围为：未受 WNV 疾病影响的地区为每 1000 人 3.2 例，而罗维戈省一个受影响严重的地区为每 1000 人 33.3 例。2010 年，意大利没有再通报发生本地感染的 WNV 疾病病例。连续第三年出现人类感染 WNV 的病例，强烈表明 WNV 已在意大利东北部成为地方病。
