We describe the geographical and temporal distribution of West Nile neuroinvasive diseases (WNND) cases in Italy from 2008 to 2011. The increasing number of confirmed human cases from eight in 2008 to 18 in 2009 and the occurrence of the virus in a larger geographical area in 2009 (moving from east to west) prompted the Ministry of Health to publish, in spring 2010, a national programme for WNND human surveillance, comprising veterinary and vector surveillance. Subsequently, in 2011, a new national plan on integrated human surveillance of imported and autochthonous vector-borne diseases (chikungunya, dengue and West Nile disease) was issued. Between 2008 and 2011, 43 cases of WNND were reported from five regions in Italy with a case fatality rate of 16%. The incidence of WNND during the entire study period was 0.55 per 100,000 population (range: 0.06–0.23 per 100,000). During 2011, two new regions (Friuli-Venezia Giulia and Sardinia) reported confirmed cases in humans. Integrated human, entomological and animal surveillance for West Nile virus is a public health priority in Italy and will be maintained during 2012.
我们描述了 2008 年至 2011 年意大利西尼罗河神经疾病（WNND）病例的地理和时间分布。确诊病例数量从 2008 年的 8 例增加到 2009 年的 18 例，病毒在 2009 年的地理范围也扩大了（从东向西移动），这促使卫生部在 2010 年春季发布了一项针对 WNND 人类监测的国家计划，其中包括兽医和病媒监测。随后，2011 年，又发布了一项关于输入性和本土媒介传播疾病（基孔肯雅热、登革热和西尼罗河病）综合人类监测的新国家计划。2008 年至 2011 年间，意大利五个地区报告了 43 例 WNND 病例，病死率为 16%。整个研究期间，WNND 的发病率为 0.55/100000 人口（范围：0.06-0.23/100000）。2011 年，两个新地区（弗留利-威尼斯朱利亚和撒丁岛）报告了人类确诊病例。针对西尼罗河病毒的综合人类、昆虫学和动物监测是意大利的公共卫生重点，将在 2012 年继续进行。
