为定量估计我国2000年以来猪旋毛虫感染情况，检索中英文数据库，筛选整理猪旋毛虫流行情况相关文献，并提取数据进行定量分析。共入选28篇文献，涉及全国9个省份。结果显示：采用ELISA法共检测124 088份样品，阳性率为2.54%（95%CI：1.55%~3.57%）；压片镜检法共检测130 267份样品，阳性率为0.17%（95%CI：0.06%~0.34%）。2000年以来猪旋毛虫检出率逐渐降低，华南和西北地区检出率较高，农村饲养生猪检出率略高于商品场，农贸市场猪肉样品中也有检出。结果表明，我国猪群旋毛虫感染率较低，且呈下降趋势，但分布范围仍较广，有感染猪肉进入流通环节的风险，提示该病原对公众尤其是农村地区群众的健康仍造成威胁。建议对现有检测方法进行评价，同时加强对农村地区生猪屠宰的检疫和监管。
In order to quantitatively estimate the prevalence of swine trichinellosis in China since 2000，the data was extracted from Chinese and English databases and the literature related to the prevalence of swine trichinellosis for quantitative analysis. A total of 28 articles from 9 provinces were selected，which introduced that a total of 124 088 samples were detected by ELISA，and the positive rate was 2.54%（95%CI：1.55%~3.57%），while 130 267 samples were examined by microscope，and the positive rate was 0.17%（95%CI：0.06%~0.34%）. The detection rate of trichinellosis had gradually decreased since 2000，was higher in South China and Northwest China，and slightly higher in pigs in rural regions than those in commercial farms，which was also detected out in pork samples from farmers' markets. In conclusion，the infection rate of Trichinella spiralis was low in pigs in China，and trended to decrease，but it was still widely distributed with potential risk of spreading via infected pork，posing a threat to the health of the public，especially those in rural regions. Therefore，it was suggested to evaluate current detection methods and to strengthen quarantine and supervision for pig slaughtering in rural regions.
