In pictures: Battling hunger and Aids in Swaziland

Mgubelo Mamba is an HIV-positive farmer from Swaziland - the country with the world's highest rate of HIV/Aids.

Although almost 40% of Swazis are HIV-positive, Mr Mamba says stigma and ignorance remain widespread.

"People ask: 'Are you positive?' They can’t believe I am able to work."
