To reassess the schistosomiasis problem in Ngamiland and especially in Maun area 552 primary school children and 213 adult labourers were examined with urinalysis and rectal snip. Of the pupils 80.3% were found positive for S. mansoni and 1.4% for S. haematobium; of the labourers 35.7% were infected with S. mansoni and 0.5% with S. haematobium. There was no difference between the sexes; prevalence decreased by age. In Seronga village 102 pupils were examined; 69.6% were positive for S. mansoni. The decrease in prevalence in the higher age groups may be explained by recent introduction of the agent in the area.
为重新评估恩加米兰德地区尤其是马翁地区的血吸虫病问题，对552名小学生和213名成年劳动者进行了尿液分析和直肠活检检查。在学生中，发现80.3%的人曼氏血吸虫检测呈阳性，1.4%的人埃及血吸虫检测呈阳性；在劳动者中，35.7%的人感染了曼氏血吸虫，0.5%的人感染了埃及血吸虫。男女之间没有差异；患病率随年龄下降。在塞龙加村，对102名学生进行了检查；69.6%的人曼氏血吸虫检测呈阳性。较高年龄组患病率的下降可能是由于该地区最近引入了病原体。
