Prince Harry has launched a campaign on World Aids Day to combat HIV stigma by telling people to share their secrets online.

The #FeelNoShame campaign, which features celebrities such as singer Nicole Scherzinger and actress Gemma Arterton, asks people across the globe to share their secrets in a video online, in order to raise awareness of the difficulty many living with HIV find in speaking up and seeking support.

"Globally, HIV is the second highest cause of death amongst those aged between 10-19 years old, and it is the number one cause of death across Africa," said Prince Harry

"One tragic issue in particular is the shame and stigma linked to HIV. This causes thousands of children to needlessly die each year because they're keeping their illness a secret and not getting the medical attention they need.

"To show our support for the children of Lesotho, and help reduce the stigma for all those affected by HIV, we are turning this World AIDS Day into a day in which no one should feel any shame about their secrets. Together, we can tackle the stigma surrounding HIV and give the young people carrying it the childhood they deserve. The childhood so many of us take for granted," he added.
