Background  In the era of anti-retroviral therapy (ART), the plasma HIV viral load (VL) is an important primary indicator for monitoring the HIV treatment response. To optimize the clinical management of HIV/AIDS patients, we investigated VL high-risk events related to virological failure (VF) and further explored the preventive factors of VL high-risk events.    Methods  The data were derived from China’s HIV/AIDS Comprehensive Response Information Management System. HIV infected patients who initiated or received ART in Guangxi between 2003 and 2019 were included. The contributions of VL after 6 months of ART to VF and AIDS-related death were analysed by Kaplan-Meier curves, log-rank tests and Cox regression analyses. Both descriptive analyses and bivariate logistic regression were employed to further explore the preventive factors related to VL high-risk events of VF.    Results  The cumulative rates of VF in the high low-level viremia group (high LLV) ( χ   2   = 18.45;  P  <  0.001) and non-suppressed group ( χ   2   = 82.99;  P  <  0.001) were significantly higher than those in the viral suppression (VS) group. Therefore, the VL high-risk events of VF was defined as highest VL > 200 copies/ml after 6 months of ART. Compared with the VS group, the adjusted hazard risk was 7.221 ( 95% CI : 2.668; 19.547) in the high LLV group and 8.351 ( 95% CI : 4.253; 16.398) in the non-suppressed group. Compared with single patients, married or cohabiting ( AOR  = 0.591;  95% CI : 0.408, 0.856) and divorced or separated ( AOR  = 0.425,  95% CI : 0.207, 0.873) patients were negatively associated with VL high-risk events. So were patients acquired HIV homosexually ( AOR  = 0.572;  95% CI : 0.335, 0.978). However, patients who had ART modification were 1.728 times ( 95% CI : 1.093, 2.732) more likely to have VL high-risk events, and patients who used cotrimoxazole during ART were 1.843 times ( 95% CI : 1.271, 2.672) more likely to have VL high-risk events.    Conclusions  A VL greater than 200 copies/ml is a VL high-risk event for VF. Intervention measurements should be adopted to optimize the surveillance of ART in patients who are single or widowed, who have ART modification, and who use cotrimoxazole during ART.
