Schistosomiasis japonica has long been endemic in the People's Republic of China. In the 1950s, the number of the infected persons was estimated at 10 million; infected snail habitats were estimated at more than 14 billion square metres and infected cattle at 1.2 million. After schistosomiasis control measures were carried out, it was a great success. According to the survey of 1989, infected persons were estimated at 0.95 million; infected snails at 3.47 billion and infected cattle at about 0.1 million. These results compared with those of the 1950s show big reductions in prevalence rates 90.5%, 75.2% and 91.6%, respectively. At present, the disease is a threat in the marshland and lake regions and the high mountainous regions. To maintain the success achieved in effective control and to bring the yet endemic marshland and lake regions and mountainous areas under control are hard and long-term tasks confronting the People's Republic of China.
日本血吸虫病长期以来在中国流行。20世纪50年代，估计感染人数达1000万；感染钉螺的孳生地估计超过140亿平方米，感染牛120万头。实施血吸虫病防治措施后，取得了巨大成功。根据1989年的调查，估计感染人数为95万；感染钉螺34.7亿只，感染牛约10万头。这些结果与20世纪50年代相比，患病率分别大幅下降了90.5%、75.2%和91.6%。目前，该病在沼泽地、湖区和高山区仍构成威胁。巩固有效防治成果，控制仍有血吸虫病流行的沼泽地、湖区和山区，是中华人民共和国面临的艰巨而长期的任务。
