Since last October, 470 cholera cases have been recorded in the region, Dodoma Regional Medical Officer James Kiologwe said.

Efforts are underway to contain the disease, particularly in the harder hit areas, including educating people to observe general hygiene.
"A team of health practitioners has been dispatched in those areas to educate people on the effective use of latrines or other sanitation systems, like chemical toilets, and encourage them to ensure that they wash hands with soap and safe water after toilets," the official said.
