This maybe prince Harry's first trip to Mildmay hospital, but already there is a much stronger bond than your average royal visit, they still talk about the time his mother came here in the 80s and 90s, stories Harry was keen to hear more about. Even if some of those stories were more about him and his brother. From a casual handshake to kissing a patient who had aids, her actions were credited with breaking down the stigma at a time when this hospital was having its windows smashed simply for helping those with HIV. Cameras weren't allowed to film prince Harry meeting patients, but he was introduced to staff who met his mother like office manager Sharon Smith who has worked here for over 20 years.She was a very knowledgeable lady, she was very keen on what we did here at Mildmay, and she wanted to meet everybody, and she had private times with some of the patients, she'd go to every room to meet them and have a chat with them.

Through his charity in Africa that helps children with HIV and aids, Harry has already become a global ambassador for the cause, while he maybe happy to talk about the issue, experts say a reluctance to be tested is still a big problem not just in Africa, but also in the UK, advancements in medication mean people are living longer with HIV, but late diagnosis makes treatment much harder.

There are something frightened of testing, the message really is trying to get tested early, because if you can get tested early, then you can get onto the treatment regime which will be quite effective.

Charity is continuing to celebrate the impact that princess Diana had on the cause of HIV and aids, however for prince Harry this is about making his own personal mark on an issue that still decades on continue to be surrounded by stigma for some.
