ResultsThe positive rate of human immunodeficiency virus antibody （anti-HIV） was 0.045%； positive rates of syphilis antibody （anti-TP） and HBsAg were 4.64% and 0.64%， respectively. The positive rates of anti-HIV， anti-TP and HBsAg varied from 2018 to 2021， but the differences were not statistically significant （P>0.05）. The positive rate of HBsAg increased gradually with the increase of maternal age， and the difference was statistically significant （P<0.01）. There were 16 mixed infections among 1 309 positive cases， 15 of which were hepatitis B and syphilis mixed infections. ConclusionThe infection of AIDS， syphilis and hepatitis B in pregnant women in Yueyang City is relatively high.
