When Innocent Havyarimana started his soap-making business in Kenya s Kakuma refugee camp in early 2015, he was trying to move on from the traumatic events that had made him flee his native Burundi a year earlier.
Little did he know that his cottage enterprise would become a major weapon in the fight against coronavirus in one of the world s biggest settlements of its kind - Kakuma is home to almost 200,000 people.
As soon as the former chemistry student realised the importance of hand-washing in tackling the spread of Covid-19, he lowered prices and started to offer his products in smaller quantities and sizes, to make them more affordable.
