【Abstract】ObjectiveTo investigate the infection conditionofhuman T-cellymphotropic virus（HTLV）among voluntaryblooddonors in Qinzhou City，soasto provideabasis forformulating blood screning strategiesin China.MethodsA totalof74716bloodsamples werecolectedfromvoluntaryblooddonorsinQinzhou CityfromJuly2022 toMay2024.The antibodies against HTLV-1/2 weredetectedbydouble-antigensandwich enzyme-linked immunosorbentassy（ELISA）Samples thatshowedreactivityweresenttothe Guangxi Blood Center forfurtherconfirmationbyWesternblot（WB）andrealtimefluorescent quantitativepolymerasechainreaction（PCR）．ResultsAmongthe74716blood donorsamplestested by ELISA，10 cases were positive for HTLV-1/2 antibodies，with a preliminary sreening positivity rate of O .134‰ ；among the 10 initiallyscreened positiveblooddonors，onecase wasconfirmedtobepositiveforHTLV-1，withaconfirmed positivity rate of 0.0134%o ，no HTLV-2 positive blood donors were detected，and the confirmed positive donor was a Han Chinese of Qinzhou native.ConclusionCurrntly，there isno HTLV-2 infection detectedamong voluntary blood donorsinQinzhou City.However，alow level of HTLV-1infection，mainlyamong local residents，doesexist.Continuousmonitoring istil neded.Toensure bloodsafety，efectivepreventiveandcontrol measuresshouldbetakentoreducetheriskofHTLVtransmission through blood.
