The areas newly affected by the outbreak include the Pwani coast, Dar es Salaam, Morogoro and Iringa.
Cholera is considered a diarrhoeal disease. African countries have recurrent cholera outbreaks due to poor sanitation and hygiene as well as inadequate preparedness and capacities.
Earlier cholera outbreaks in Tanzania have been based in the Kigoma region. Those outbreaks were just declared over when the new cases were reported.
There have now been 857 cumulative cases of cholera in the affected areas; 13 people have died from the outbreak. Laboratory results show the outbreak is caused by Vibrio cholera, type O1 Ogawa strain.
There has only been one case reported in Morogoro, and Dar es Salaam has seen the most cholera cases.
Health officers have begun to include the community in their prevention efforts by offering disinfectants, such as chlorine tablets, and educating local residents. Health workers also have been traveling from house to house to offer their services.
