Abstract：
African swine fever (ASF) is a severe viral disease characterized by high lethality in suids and caused by the African Swine Fever Virus (ASFV). The ASF genotype I virus was introduced to Europe in 1957, marking the onset of the first European epidemic wave. In 2007, ASFV genotype II was detected in Georgia, affecting domestic pigs and wild boars before spreading to various European and extra-European countries, including Italy. The first case of ASFV in Italy was documented on 7 January 2022, in a wild boar in the Piedmont region. Since then, several ASFV-positive wild boar carcasses have been identified in the Piedmont and Liguria regions. By June 2023, ASFV had spread to Lombardy, one of the major pig-producing regions in northern Italy; the virus was first detected in early summer in wild boar carcasses. Two months later, it was diagnosed in a commercial pig farm as a consequence of the disease\'s spread amongst wild boars and an increase in the viral environmental load. This report aims to describe the features of ASFV domestic pig outbreaks that occurred in the Zinasco municipality (Lombardy) and the joint efforts to mitigate potential direct and indirect economic impacts on the Italian and global pig industry. The epidemiological investigation and the measures implemented, which were all performed according to national and European regulations, as well as exceptional ad hoc measures aimed at protecting the pig industry, are described in order to provide a practical and effective approach to combating ASF.
摘要：
非洲猪瘟（ASF）是一种严重的病毒性疾病，其特征是在猪中高致死率，由非洲猪瘟病毒（ASFV）引起。ASF基因型I病毒于1957年被引入欧洲，标志着第一次欧洲流行浪潮的开始。2007年，在佐治亚州检测到ASFV基因型II，影响家猪和野猪，然后传播到欧洲和欧洲以外的国家，包括意大利。意大利的第一例ASFV病例于2022年1月7日在皮埃蒙特地区的野猪中记录。从那以后,在皮埃蒙特和利古里亚地区已鉴定出几种ASFV阳性野猪尸体。到2023年6月，ASFV已经蔓延到伦巴第，意大利北部主要的猪产区之一；该病毒于初夏在野猪尸体中首次发现。两个月后,由于这种疾病在野猪中的传播和病毒环境负荷的增加，它在一个商业养猪场被诊断出来。本报告旨在描述Zinasco市（Lombardy）发生的ASFV家猪疫情的特征，以及减轻对意大利和全球养猪业的潜在直接和间接经济影响的共同努力。流行病学调查和实施的措施,这些都是根据国家和欧洲的规定进行的，以及旨在保护养猪业的特殊临时措施，为了提供一种实用有效的方法来对抗ASF。
