间日疟的潜伏期过去认为是9～20天(短潜伏期),从初发到再次复发的潜隐期长短不一,长期以来认为继发性红细胞外期是间日疟复发的根源,但从近年来动物实验的肝组织切片等的观察来看,此一学说已不能成立。在1975年世界卫生组织的专家会议上否定了上述学说,并提出了子孢子休眠学说。本世纪以来,国内外有许多长潜伏期间日疟的报告,有长达6个月以上至628天的。有不 The latency to vivax malaria was thought to be 9 to 20 days (short latency), and the range of latency from initial onset to relapse was different. It has long been assumed that the secondary erythrocytic stage is the root cause of recurrence of P. vivax In recent years, animal experiments such as the observation of liver sections, this doctrine can not be established. At the 1975 expert meeting in the World Health Organization, the above theory was rejected and the sporozoan dormancy theory was put forward. Since the beginning of this century, there have been many reports both domestically and internationally about vivax malaria in the long incubation period, lasting more than 6 months to 628 days. No
