HIV positive rates among syphilis and HSV-2 In non-syphilis and non-HSV-2 infected patients (χ2 = 7.79, P = 0.005; χ2 = 6.57, P = 0.01). Conclusion MSM in Zhengzhou has a high prevalence of HIV infection and prevalence of high-risk sexual behaviors. STD patients are at high risk of HIV infection and should be the focus of HIV / AIDS prevention and control.
