The descriptive statistics were presented using the Korea HIV\/AIDS cohort data (2006-2016).RESULTS: Men accounted for 93.3% of the total number of respondents, and approximately 55.8% of respondents reported having an acute infection symptom. According to the transmission route, infection caused by sexual contact accounted for 94.4%, of which 60.4% were caused by sexual contact with the same sex or both males and females. Participants repeatedly answered the survey to decrease depression and anxiety scores. Of the total participants, 89.1% received antiretroviral therapy (ART). In the initial ART, 95.3% of patients were treated based on the recommendation. The median CD4 T-cell count at the time of diagnosis was 229.5 and improved to 331 after the initial ART. Of the patients, 16.6% and 9.4% had tuberculosis and syphilis, respectively, and 26.7% had pneumocystis pneumonia. In the medical history, sexually transmitted infectious diseases showed the highest prevalence, followed by endocrine diseases. The main reasons for termination were loss to follow-up (29.9%) and withdrawal of consent (18.7%).CONCLUSIONS: Early diagnosis and ART should be performed at an appropriate time to prevent the development of new infection.<\/jats:p>","DOI":"10.4178\/epih.e2019037","type":"journal-article","created":{"date-parts":[[2019,9,3]],"date-time":"2019-09-03T05:51:59Z","timestamp":1567489919000},"page":"e2019037","update-policy":"https:\/\/doi.org\/10.4178\/crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Epidemiological
