A regional health official, Abdulmunhem Al-Beshir, said that “some 131 people have been infected in the outbreak while nine others died,” ETV said.
Cases have been reported in three districts, according to the Benishangul-Gumuz Health Bureau.
Meanwhile, a cholera outbreak also killed nine Sudanese refugees in Ethiopia’s north-western Amhara region.
Local media say the cholera outbreak has spread through 11 regions of Ethiopia in the past year, killing 320 people.
A two-year civil war and a drought have caused a severe humanitarian crisis in the region.
