一治疗及临床研究通过大规模的血吸虫病防治工作,使我们对本病获得了广泛而深入的了解。流行区患者往往经过反复多次的不同程度的感染,但不一定有急性病史,因此,以一次感染来划分病期不甚恰当,而依病情来分期较为合理。我们曾简分为隐匿、急性和慢性三个期,后者又分为慢性早期和慢性晚期。流行区以慢性早期和隐匿期患者最为多见。隐匿期患者症状虽不明显,但粪便排卵是重要的传染源,因此我们仍将他们列为治疗对象。 A treatment and clinical research through large-scale schistosomiasis prevention and control work, so that we get a broad and in-depth understanding of the disease. Patients in endemic areas are often repeatedly infected with different degrees of infection, but not necessarily have an acute history, therefore, an infection to divide the disease is not appropriate, but according to the disease to stage more reasonable. We have briefly divided into three periods of occult, acute and chronic, the latter is divided into chronic early and chronic. Popular areas with chronic early and occult patients the most common. Although the symptoms of patients in the hidden period are not obvious, but the feces ovulation is an important source of infection, so we still treat them as a treatment.
