Objective To understand the characteristics of HIV testing and HIV infection status among 138 sexual partners of HIV positive MSM in Zhejiang province.Methods A cross-sectional study was conducted among the selected sexual partners of HIV positive MSM diagnosed between September,2015 and September,2016 in the cities of Hangzhou,Ningbo,and Wenzhou in Zhejiang by using self-administrated questionnaire.Information was collected on socio-demographic characteristics,periodic testing,and'dating someone by informed of his HIV status beforehand(informed dating)'.Results The HIV-infected MSM helped recruit a total of 138 sexual partners in this study.Among them,those reported as being fixed homosexual partners and temporary homosexual partners received periodic HIV testing of 16/46,and 16/53 respectively.Regarding the dating,15/46 of the fixed and 36/53 of temporary homosexual partners knew or partially knew the status of HIV infected MSM before each intercourse,with the difference statistically significant(χ~2=12.297,P<0.000).33/46 and 31/53 of the fixed,and temporary homosexual partners wanted to know HIV status of the partners before sex.HIV positive rates of fixed homosexual partners,casual homosexual partners and spouses were 13/46,2/53 and 4/39.Those who knew or partially knew HIV status of their sexual partners had lower rate of HIV infection 2/51,than those who did not know HIV status 13/48.Conclusion Fixed homosexual partners are less likely to know the status of HIV infection of their sexual partners than temporary homosexual partners,who are more anxious to know the HIV status of their sexual partners.Informed dating should be encouraged to reduce HIV infection among homosexual sex partners.
