Among patients who are infected with NG, a proportion of them would not to seek medical service because of asymptomatic infections or other reasons. These patients would like to choose private clinics or some irregular private hospitals where gonorrhoea cases are not mandatory reported to CISDCP, and the others would go to general hospital which mandatory reporting STD cases to CISDCP. Next, on the basis of the suggestion of physicians and the decision of patients, some of the patients would get the NG test done, and the others would not. Among gonorrhoea patients who were tested for NG, some of them would receive a true-positive result and be diagnosed with gonorrhoea, and the others' results would be false negative. Except them, some of the other people who did not have NG infection but got NG test done and got false-positive results would be wrongly diagnosed with gonorrhoea. Among the diagnosed gonorrhoea cases (including the true positive and false positive), most of them would be reported to CISDCP as required, and some of them would not because of the negligence of physicians. Our study focused on the clinical diagnosis of gonorrhoea and subsequent reporting as presented within the dashed frame.
