The large foci of trichinellosis are mainly located in the southeastern, the central and northeastern China. By the end of 1999, human cases with trichinellosis have been recorded in 17 out of 34 Provinces/Autonomous Regions/Municipals (P/A/M) of China. The seroepidemiological surveys of T. spiralis infection in humans were carried out in nine out of 34 P/A/M. The overall seroprevalence was 5.3%. The prevalence detected by muscle biopsy in Henan province was 2.5%. From 1964 to 1999, 548 outbreaks of trichinellosis, with 23,004 cases and 236 deaths, were recorded in 12 P/A/M of China. Pork is the predominant source of outbreaks of human trichinellosis in China, 525 (95.8%) out of 548 outbreaks were caused by eating pork. However, 14 outbreaks resulting from the consumption of mutton and game meat occurred in recent years, suggesting the increasing significance of herbivorous and wild animals as source for human trichinellosis.
旋毛虫病的大流行区主要位于中国东南部、中部和东北部。截至1999年底，中国34个省/自治区/直辖市中有17个报告了旋毛虫病病例。在34个省/自治区/直辖市中的9个开展了人体旋毛虫感染血清流行病学调查，总体血清阳性率为5.3%。河南省肌肉活检检出率为2.5%。1964年至1999年，中国12个省/自治区/直辖市记录了548起旋毛虫病暴发，23004例病例，236例死亡。猪肉是中国人体旋毛虫病暴发的主要来源，548起暴发中有525起（95.8%）是因食用猪肉所致。然而，近年来有14起因食用羊肉和野味导致的暴发，这表明食草动物和野生动物作为人体旋毛虫病来源的重要性日益增加。
