The aim of the study was to determine the overall prevalence of classical swine fever (CSF) in pigs in India, through a systematic review and meta-analysis of published data.
Consortium for e-Resources in Agriculture, India, Google Scholar, PubMed, annual reports of All India Coordinated Research Project on Animal Disease Monitoring and Surveillance, and All India Animal Disease database of NIVEDI (NADRES) were used for searching and retrieval of CSF prevalence data (seroprevalence, virus antigen, and virus nucleic acid detection) in India using a search strategy combining keywords and related database-specific subject terms from January 2011 to December 2015 in English only.
A total of 22 data reports containing 6,158 samples size from 18 states of India were used for the quantitative synthesis, and overall 37% (95% confidence interval [CI]=0.24, 0.51) CSF prevalence in India was estimated. The data were classified into 4 different geographical zones of the country: 20% (95% CI=0.05, 0.55), 31% (95% CI=0.18, 0.47), 55% (95% CI=0.32, 0.76), and 34% (95% CI=0.14, 0.62). CSF prevalence was estimated in northern, eastern, western, and southern regions, respectively.
This study indicates that overall prevalence of CSF in India is much lower than individual published reports.
本研究旨在通过对已发表数据进行系统评价和荟萃分析,确定印度猪群中经典猪瘟(CSF)的总体流行率。
利用印度农业电子资源联盟、谷歌学术、PubMed、全印度动物疾病监测与防控协调研究项目年度报告以及NIVEDI(NADRES)的全印度动物疾病数据库,仅使用英文,采用结合关键词和特定数据库相关主题词的检索策略,搜索和检索2011年1月至2015年12月印度CSF流行率数据(血清流行率、病毒抗原和病毒核酸检测)。
共有来自印度18个邦的22份包含6158个样本量的数据报告用于定量综合分析,估计印度CSF总体流行率为37%(95%置信区间[CI]=0.24, 0.51)。数据被分为该国4个不同的地理区域:分别为20%(95% CI=0.05, 0.55)、31%(95% CI=0.18, 0.47)、55%(95% CI=0.32, 0.76)和34%(95% CI=0.14, 0.62),分别估计了北部、东部、西部和南部地区的CSF流行率。
本研究表明,印度CSF的总体流行率远低于个别已发表的报告。
