"Most of them die on their way to hospitals at the main towns in the region," he said.
The recent cholera outbreak has occurred in three southern regions of Somalia: Banadir, Gedo and Lower Shabelle.
Somalia has some of the world's worst health indicators, with life expectancy at birth is 46 years, while on average a quarter of children die before they reach the age of five.
The first reported outbreaks of cholera in Somalia came in December last year, with reports of outbreaks in the four central regions of the country. Doctors say it has now spread.
