To my surprise the journey had only taken 20 minutes – I’d allowed an hour more than that. It’s 8am, I’ve just driven off the ring road and I’m parked between a mountain of huge sewer pipes and a local pharmacy. People, goats and dogs are milling around my vehicle as I wait for Andy to come and guide me to the ACT (“AIDS Care and Treatment”) Project compound in the middle of the expanse of slums in front of me.
