A sample should be given to improve the intensity of contact-tracing. Therefore three re-interviews were performed in two groups of patients suffering on gonorrhoea (Group A=1000;Group B=110 persons) with the aim to find out, how many persons could be traced more by re-interviews and could be found infected with gonorrhoea too. By re-interviews 12.0% more contacts could be traced, of whom 55.5% were infected.
应提供样本以提高接触者追踪的强度。因此，对两组淋病患者（A组 = 1000人；B组 = 110人）进行了三次重新访谈，目的是查明通过重新访谈可以多追踪到多少人，以及这些人中有多少也被发现感染了淋病。通过重新访谈，可以多追踪到12.0%的接触者，其中55.5%被感染。
