Abstract: Objective Describe and analyze the epidemiological characteristics of foreign HIV (AIDS) and AIDS patients (HIV/AIDS cases) in Shenzhen from 2004 to 2017 and the differences in case characteristics between different time periods. Methods Basic information on foreign HIV/AIDS cases during 2004-2017 were analyzed by descriptive epidemiological method. Results A total of 111 cases of foreign HIV/AIDS cases were reported in Shenzhen from 2004 to 2017, including 100 HIV infected person and 11 AIDS patients.

Among the sample source distributions, 60.36% were diagnosed in prisons. Comparing the epidemiological characteristics of foreign cases in different time periods, the Results showed that the differences in nationality, education level, infection route, sample source, disease stage and follow-up were statistically significant (P<0.05). During 2011-2017, the detection rate of the first CD4⁺T lymphocytesin foreign cases was 76.74% (33/43)inShenzhen, and 60.61%(20/33)Results were lower than 350cells/μL. Two cases were treated with antiviral therapy. Conclusion The epidemiological characteristics of foreign HIV/AIDS caseslived in Shenzhen were significantly changed recently.
