Yusupha Mbye's mother pushes his wheelchair slowly across the tiled compound of their home in Kanifing, about 11km (seven miles) from The Gambia's capital, Banjul. The late-afternoon sun hangs low as she pauses to straighten a wrap over his legs, stopping briefly to catch her breath. He has been in this wheelchair since he was a teenager, she told Al Jazeera, wiping away tears. Twenty-six years later, I am still caring for him.
