Through media coverage of her work, she helped to start conversations and change attitudes towards conditions like HIV/AIDS and leprosy.
HIV/AIDS
During the mid-1980s, a global lack of conversation about HIV/AIDS was causing a lack of understanding of the condition, and reinforcing existing stigma and prejudice towards gay men. Many world leaders shied away from talking about the HIV epidemic as tens of thousands of people lay dying.
In April 1987—when many people didn't understand that HIV couldn't be contracted through skin-on-skin contact—Princess Diana shook the hand of a patient living with the condition in front of the world's media.

She visited hospitals at home and abroad and was photographed holding hands and talking with patients. Activists believe these small acts helped change attitudes towards HIV/AIDS and a crucial point in history.

Diana helped raise global awareness of the impact of landmines by visiting those living with life-changing injuries sustained as a result of the devices.
On 15 Jan. 1997—the year that Princess Diana died—she walked through an active minefield in Angola and detonated a mine in front of a crowd of reporters with the assistance of a land mine expert.

While there, Diana championed the Ottawa Treaty, the aim of which was to eliminate anti-personnel landmines around the world. To date, there are 162 member states committed to the treaty.

In the late 1980s, Princess Diana helped dispel one of the myths surrounding leprosy—that it can be contracted by touch. Activists say Diana made "huge strides" in tackling the stigma surrounding leprosy by touching those affected by the condition.

She sat on the beds of patients, shook hands with them and touched their bandaged wounds to draw attention to the myth surrounding the condition.
