HIV transmission rates are rising in China, and gay and bisexual men are the most at risk.

Male-to-male HIV infections in youth cases in China have "increased from 58.5 percent to 81.6 percent in 2015," according to the Chinese news site, The Nanfang.

HIV infections are up in China but the average age for patients with the disease has dropped over the past five years, "with 15 to 24 year-old making up 35 percent of all new cases."

The National Center for AIDS and Sexually Transmitted Disease Control and Prevention reported that 2,200 new HIV infections were reported among students over the age of 15 in 2015, up from 1,772 the year before.

One reason that infection numbers are up could be because they are now more accurate. Testing for the disease has become more accepted, with mobile testing units and at-home testing kits helping with the embarrassment and stigma that comes with testing for HIV.

In 2015 there were over 1,800 new HIV cases reported in Shangai, 70% reportedly involved men who have sex with other men.
