He was one of the first public figures, along with Princess Diana, a close friend, to change the perception of the disease. Princess Diana, John and now Harry have fought for needed funding and continued vigilance on the importance of education and resources in particularly vulnerable regions in sub-Saharan Africa.

Harry founded a charity, Sentebale, which means \"forget me not,\" in Lesotho in honor of Diana. The charity's Let Youth Lead program gives young people a public voice on the issue of AIDS and how it affects their lives.

Just last month, the prince made a private visit to Lesotho for the opening of a new dining hall at the Phelisanong Children’s Center in Pitseng.

Harry’s campaign to raise awareness and encourage testing for HIV/AIDS has included taking an HIV test together with the singer Rihanna in her home country of Barbados to show how easy the process is.

While in Amsterdam, Harry, who is sixth-in-line to the throne, also attended a reception with Invictus Games hopefuls from the Netherlands. The Paralympic-style competition for wounded sick and injured service members will be held in The Hague, Netherlands, in 2020.

Harry and Meghan will attend the 2018 Invictus Games in Sydney this October during their tour of Australia, New Zealand, Tonga and Fiji.
