The current characteristics of PrEP among MSM in China. Of the total 1915 participants, 512 (26.7%) had objective need to use PrEP, 1617 (84.4%) were willing to use PrEP, 106 (5.5%) participants reported that they could afford PrEP and only 23 (1.2%) had actual uptake of PrEP for HIV prevention. Area A represents those who are willing to use PrEP but do not have objective need, while Area B represents those who are willing to use PrEP and objectively need it. It is clear that most of the MSM population has a high willingness to use PrEP, but may not actually be the top candidates for PrEP promotion. It is also noteworthy that only 5.5% of the MSM in our study could afford PrEP, and even fewer actually used it
