An analysis of epidemiological characteristics of HIV patients infected through sex in Henan Province in 2011

Objective To analyze the social demographic and behavioral characteristics of sexually transmitted HIV patients and evaluate the risk of secondary transmission. Methods Retrospective cross-sectional study was performed to survey sexually transmitted HIV patients reported in 2011 in Henan Province. Results Females were the predominant population of marital sexual transmission, while males were the main population of extramarital spreading. The average age of extramarital sex transmission in males was significantly older than in females. Of the extra-marital sexually transmitted patients 68.0% used to have commercial hetero sex and the average commercial hetero sex partner was 3, and consistent condom use rate was 0.7% （4/578）. Of the homosexually transmitted pa- tients 90.6% （260/287）used to have non-commercial homo sex and the consistent condom use rate was 5.1%（13/257）. Conclusion High risk behavior for HIV secondary transmission was common among sexually transmitted HIV patients and targeted preventive measures should be taken to control the spread of AIDS.
