ABSTRACT
Objective To understand the risk behavioral networks of newly reported HIV infections in Taizhou prefecture, Zhejiang province. Methods Newly reported HIV infections from May 2008 through March 2010 in Taizhou prefecture were invited to participate in a cross-sectional survey which requested numbers and contact information of individuals with whom they had had high risk contacts as well as risk behavioral acts with them. Persons having had risky contacts with HIV-infected cases were thereof approached to participate in this survey and to receive HIV testing.Those who tested positive for HIV were subject to further round of the surveys. Results A total of 267 HIV cases were newly reported during this study period. Among them, 191 participated in the survey and served as 'index cases', including 158 cases identified from routine HIV surveillance programs and 33 cases identified from the present survey. Heterosexual transmission was the primary transmission route (74.9%, or 143/191 ), followed by homosexual transmission ( 19.4%, or 37/191 )and injection drug use (5.8%, or 11/191 ). These 191 HIV cases reported a total of 1152 individuals with whom they had had risky contacts. They were able to provide contact information of 461 risk contacts. Of them, 129 received HIV testing and 61 (47.3%) tested positive for HIV. HIV prevalence was the highest among spouses or long-term sex partners of HIV cases (45.6%, or 47/103) and malesex partners of HIV-infected men having sex with men (MSM) (60.0%, or 12/20). Condom use wasvery low among them, with only 33.9% consistently using condoms for sex. Conclusion Newlyreported HIV infections in Taizhou prefecture reported a large and complicated risk behavioral networks and low condom use, suggesting a potential risk of HIV among these connected people,especially among MSM. Much efforts are needed to intervene these high risk subgroups and high risk behavioral networks.
