Prevalence of Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum among outpatients in central China: A retrospective study

Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU) are the common sexually transmitted pathogens and lead to genital diseases, highly prevalent all around the world. The objective of this study was to analyze the prevalence of NG, CT and UU among outpatients in central China. A total of 2186 urogenital swabs were collected from the patients and the NG, CT and UU pathogens were testing with RT-PCR method, meanwhile the medical records were obtained from the hospital information system. The overall infection rates of NG, CT and UU were 4.57%, 6.63% and 48.81% respectively, showed the prevalence of UU was higher than NG and CT. The younger people had the highest infection rate of NG (10.81%), CT (20.54%) and UU (54.59%). Single infection (89.09%) was significant higher than co-infection (10.91%), and the CT-UU co-infection was the prominent pattern (66.41%). There were an obvious sex difference, the prevalence of NG and CT were significant higher in male, whereas UU was higher in female. Our study could contributed a better understanding of the prevalence of NG, CT and UU, facilitating to the development of effective screening, prevention and treatment policies.
