Tracing the sources of newly reported HIV infections in Dehong prefecture of Yunnan province
0bjective To trace and provide HIV-testing among those having contacts with HIV-infected individuals at various levels in Dehong prefecture，Yunnan province and to evaluate the effectiveness and feasibility of such investigation as a supplemental strategy for HIV testing and control.Methods Newly reported HIV infections from August throughout October in Dehong orelecture，in 2008 were asked to provide contact information of persons whom they had high risk contacts with.Persons having had risk contacts with HIV-infected cases werc hereof interviewed and their blood tested on the scro—status of HIV.Results A total of 335 HIV cases were newly reported during this three.month period.A total of 309 Cases of them and 148 HIV infections identified thereafter from their risk contacts were under informed consent.to participate in this study.A total number of 3395 risk contacts were reported，of whom only 20.7％(704/3395)had‘contact information’and 51.3％(361/704)were successfully located and interviewed，including 117 previously confirmed HIV infections and 244 people with unknown HIV status.The majority of them (203 or 83.2％of244)were then tested for HIV and 56(27.6％of203)were tested positive for HIV.The proportion of having detailed contact information and the proportion of being uaced or followed among reported risk contacts of HIV infections were 68.8％and 68.2％for spouses of HIV patients。respectively，which were much higher than those among commercial SeX partners(1.2％and l 6.7％)，casual sex partners(37.3％and 22.3％)and peers who sharing needles(34.1％and 56.4％).Conclusion Newly reported HIV infections reported a large number of risk contacts and new HIV infcctions were identified among them.It WaS extremely difficult to trace commercial sex partners or casual sex partners on their HIV infection status.Nevertheless.tracing the risk contacts of newly reported HIV infections seemed to be helpful in identilying new HIV infections and in understanding the nature oftransmission towards controlling the HIVepidemics.
