Objective To investigate the status of carcinogenic infection in people infected with HIV and those with negative HIV test results in VCT clinics. To analyze the epidemiological characteristics and provide scientific basis for more targeted disease prevention and control strategies.
Methods The serum levels of Epstein-Barr virus （EBV）， human herpesvirus type 8 （HHV-8） and human T-lymphotropic virus type Ⅰ （HTLV-Ⅰ） antibodies were detected by ELISA method in 224 HIV-infected patients and 480 HIV-negative visitors treated in VCT clinics during the same period from 2014 to 2017， to compare the differences in the infection rates of this virus between HIV-infected and HIV-negative individuals and to systematically analyze the correlation between viral infections and high-risk sexual behavior.
Results Among the 224 HIV-infected patients， 79 were positive for EBV antibody， with the infection rate of 35.27%； 151 were positive for HHV-8 antibody， with the infection rate of 67.41%； and 95 were positive for HTLV-Ⅰ， with the infection rate of 42.41%. A total of 480 HIV negative visitors were tested. 7 patients were positive for EBV antibody， with the infection rate of 1.46%. 26 patients were infected with positive HHV-8 antibody， with the infection rate of 5.41%. 9 patients had positive HTIV-Ⅰ antibody， with the infection rate of 1.86%. The infection rates of the three carcinogenic viruses in HIV-infected patients were all higher than those in HIV-negative groups， and the differences were statistically significant （P<0.05）.
Conclusion There is a high prevalence of three highly carcinogenic viruses in HIV-infected patients and serious co-infection. It is necessary to improve the education of safe sex among HIV-infected patients and people with high risk of infection in order to curb the epidemic of HIV and other infectious diseases.
