[Characteristics of newly reported HIV/AIDS cases in Henan province, 2010-2018].

To analyze the epidemiological characteristics of newly reported HIV/AIDS cases in Henan province during 2010-2018, and to provide theoretical evidence for strategies on prevention and control. Information about newly reported HIV/AIDS cases in Henan between January 1, 2010 and December 31, 2018 were collected from the National Comprehensive HIV/AIDS Information System. Excel 2010 and software SPSS 23.0 were used for data cleaning and statistical analysis. During 2010-2018, a total of 41 223 HIV/AIDS cases were newly reported in Henan, and the number of newly reported HIV/AIDS cases increased from 3 087 in 2010 to 5 910 in 2018. Sexual contact was the predominant transmission route in newly reported HIV/AIDS cases, and the proportion of sexual transmission increased from 50.6 (1 564/3 087) in 2010 to 98.8 (5 839/5 910) in 2018. The proportion of heterosexual transmission firstly increased from 44.9 (1 387/3 087) in 2010 and then declined to 65.7 (3 885/5 910) in 2018, and the proportion of MSM behavior related transmission increased from 5.7 (177/3 087) in 2010 to 33.1 (1 954/5 910) in 2018. Among the newly reported heterosexual transmitted cases, the proportion of cases with non-marital heterosexual behaviors increased from 69.4 (962/1 387) in 2010 to 91.7 (3 562/3 885) in 2018 ((2)=657.802, <0.001). The number of newly reported HIV/AIDS cases in young people aged 15-24 years and old people aged ≥60 years increased year by year. The youth cases were mainly infected by MSM behavior transmission (52.7, 2 561/4 856), and heterosexual transmission was the main infection route of the elder cases (86.4, 5 907/6 833). Among the elder cases infected by heterosexual transmission, cases with non-marital heterosexual behaviors were mainly males, the number of male cases increased from 122 in 2010 to 738 in 2018, and sex composition ratio was between 82.2 and 91.0, while the sex composition ratio of female cases was increased from 9.0 (12/134) in 2010 to 17.8 (160/898) in 2018. From 2010 to 2018, the number of newly reported HIV/AIDS cases in Henan increased. Sexual transmission had become the main transmission route. AIDS prevention and control should focus on the control of non-marital heterosexual transmission and MSM behavior transmission, and to pay more attention to young people and people aged 60 years and above.
