The men sitting in the shade of a large thorn tree on the outskirts of Kano-Angola village, 10 miles inland from the shores of Lake Victoria in Kenya’s Nyanza province, are in buoyant spirits today. There is bravado, there are lewd jokes, but there are also long periods of silence.

One man in particular commands attention. As soon as he begins to talk, the rest of the group listen deferentially. Esban Ochanga is tall and slender with a far-away look in his eyes. He has called the men together to talk about the practice of widow cleansing, whereby Luo women, after the death of their spouse, are pressurized into having unprotected sex; ostensibly to allow their husband’s spirit to roam free in the afterlife. It is a tradition rarely spoken about in public. ‘I knew my brother had died and they told me it was AIDS, but I thought a Luo could not die because of that virus,’ says Ochanga. ‘So I cleansed his widow and I contracted HIV. That is what killed my first wife.’
