[Recent infected and newly reported HIV cases in Jiangsu province, 2011-2013]

To understand the status of recent infected and newly reported HIV cases in Jiangsu province.

Information including general demographic, mode of transmission and sample source of newly reported HIV infected cases was collected. Corresponding serum or plasma samples were collected and tested with BED-CEIA. Proportions of recent HIV infections among different populations were calculated, and associated factors of recent HIV infection calculated.

Among cases infected through different channels as homosexual, heterosexual and needles sharing, the proportions of recent infections were 29.19% , 17.40% and 21.75% , respectively. Statistically significant difference was seen between different populations(P < 0.05). Compared with female cases, male cases were more likely to be recent infected (OR = 1.569, 95%CI: 1.168-2.107). Compared with cases older than 35 years of age, the ones that younger than that age were more likely to be recently infected (OR = 1.556, 95% CI:1.289-1.879). Compared with cases who remained single, those married cases were more likely to be long-term infections(OR = 0.789, 95%CI:0.649-0.960). Compared with patients identified by hospitals, the recent HIV infections were more likely to be found through voluntary counseling programs and testing (OR = 2.278, 95%CI: 1.853-2.801), project-based surveillance programs (OR = 2.409, 95%CI:1.860- 3.120), and unpaid blood donation sites (OR = 2.911, 95%CI:2.118-4.001)(P < 0.05).

Proportion of MSM ranked 1st in the newly reported HIV cases in Jiangsu province. Related HIV case-finding programs should be strengthened to reduce the secondary transmission.
