In July 1994, one of the worst ever cholera epidemics broke out among nearly one million Rwandan refugees in Goma, eastern Zaire.

The United Nations High Commission for Refugees estimated that nearly 12,000 people died during the epidemic.

On one day alone I remember 1000 people died, sometimes they simply collapsed crossing the road in front of our car.

This boys father died at the side of the road just as I passed by. They were part of a column of refugees heading for help at an aid station a couple of miles further up the road..

His companions, too sick to help, simply kept walking. A family from a nearby hut came and took the child in.
