From 2007 to 2016, the numbers of HIV/AIDS students aged 15 to 24 showed an increasing trend ( χ2=6.173, P=0.013). The proportion of same-sex transmission among young students was higher than that of all cases (P<0.05). The majority of HIV/AIDS students were male, accounting for 98.8%; current local resident accounts for 69.2%; the sexual transmission accounted for 98.2%, while the same-sex transmission accounted for 83.7%; the ways to find out were mainly the survey and thematic surveys, accounting for 36.1% and 33.3% respectively; 97.0% students had completed the CD4+ testing for the first time; CD4+ level larger than 500 case/μL was 43.3%.
