[The Recent HIV-1 Infections in Blood Donors of Fuzhou Zone].

Abstract

OBJECTIVE\nTo investigate the recent HIV-1 infections of the blood donors in Fuzhou zone.\n\n\nMETHODS\nThe positive HIV antibody confirmatory samples in Fuzhou zone from 2012 to 2016 were collected and tested by LAg-Avidity EIA, and HIV long-term infections or recent infections were determined.\n\n\nRESULTS\n405 371 cases of blood donors were tested in the period from 2012 to 2016, and 94 HIV confirmatory positive samples were collected. 35 cases were recent infections determined by LAg-Avidity EIA, the annual HIV-1 incidences were 1.326‰, 0.845‰, 0.694‰, 1.148‰ and 0.364‰, the average incidences were 0.863‰. Among 94 cases of HIV confirmatory positive donors，58 cases were first donors and 36 cases were repeated donors, 17(29.3%) and 18 (50.0%) cases were recent infections respectively, which showed statistical significance（χ2=4.07，P＜0.05）.\n\n\nCONCLUSION\nThe HIV-1 incidences were stable among blood donors in Fuzhou zone. The percentage of HIV-1 recent infections in repeated donors were more higher than that in first donors.
