Health Minister Obadiah Moyo announced on Tuesday that more than 2,000 people have been diagnosed to have contracted the water-borne disease in the capital alone, with several other cases recorded around the country.
He said the high number of cases in Harare has forced the government to declaring an emergency in the capital.
"This will enable us to contain cholera and typhoid in the city as quickly as possible,” Moyo told journalists after visiting a cholera treatment centre in Harare.
The outbreak that started in Harare two weeks ago has now spread to four other provinces. These are Manicaland, Mashonaland Central, Masvingo and Midlands provinces.
The outbreak is attributed to lack of clean water supply and poor sanitation in most Zimbabwean cities.
The latest outbreak raises fears of a repeat of the 2008 episode when over 100,000 people were infected and more than 4,000 died.
