For the second year in a row the charity Water Aid has highlighted Ethiopia's poor record when it comes to access to toilets at home.
On World Toilet Day, it has reported that 93%of Ethiopians lack basic sanitation where they live, making it the lowest ranked nation on the continent.
For Chad, Madagascar and South Sudan the figure is 90%.
In sub-Saharan Africa overall more than 340 million children do not have access to a decent toilet, thereby increasing the risk of death from diseases like diarrhoea, Water Aid says.
The report also highlighted the lack of toilets in schools for children, with 60% of schools in the region without toilets.
