Imagine a city full of filth and disease. There’s precious little plant life as most of the streets are taken up by a quagmire of mud, while the houses are tumbledown shacks held together by spit and goodwill. People greet each other with smiles and nods, but the next minute will be gripped by a fit of hacking coughs that sees them bent double in agony. Children draw lines in the mud and construct elaborate games. Needless to say, people look out for each other, knowing that they haven’t got long. It’s a young population, with an average age of 25, a testament to this debilitating plague. There’s no governing structure, no system in place – but a lot of love.
