Harry, 32, visited NAZ, a sexual health charity in Fulham, London, in his mission to raise awareness of HIV and AIDS, particularly among those in his generation.
Harry, the fifth-in-line to the British throne, urged young people to fight against complacency and delivered a reminder that there is still much to be accomplished in the fight against HIV and AIDS.
Harry was also treated to a performance by the Joyful Noise choir, which is comprised of people living with HIV. Harry watched as the choir sang "No Woman No Cry" by Bob Marley.
Harry's mother, the late Princess Diana, was one of the first public figures who tried to de-stigmatize HIV and AIDS and Harry has carried on her work. Harry underwent an HIV test in July that was broadcast live on the royal family's Facebook page to show people just how simple it is to get tested.
Later in July, Harry spoke at the International AIDS Conference in Durban, South Africa, and participated in a talk with AIDS activist and musician Elton John.
"It is time for a new generation of leaders to step forward. It is time for us to step up to make sure no young person feels any shame in asking for an HIV test," Harry said at the conference. "It is time for us to step up and acknowledge that stigma and discrimination still act as the greatest barrier to us defeating this disease once and for all."
Harry has been back at work, attending a series of engagements over the last week since news of his relationship with American actress Meghan Markle became public.
Harry was seen today wearing a beaded bracelet identical to the bracelet that Markle, 35, showed off in an Instagram post. Markle’s bracelet has been reported to possibly be a gift from Harry.
Markle was seen in London last weekend buying groceries and returning with them to Harry’s home at Kensington Palace. Harry visited Markle over Halloween weekend in Toronto, where she films the legal drama “Suits.”
Harry will depart this weekend for a two-week tour of the Caribbean on behalf of his grandmother, Queen Elizabeth II.
