The city of Gweru has declared an outbreak of typhoid in Mkoba 15, 18 and 20.
Gweru Town Clerk, Elizabeth Gwatipedza said council received results from an independent laboratory confirming that there is typhoid in some parts of Mkoba high density suburb.
In the past weeks, there have been several reports of diarrhoea cases and four died in suspected typhoid cases.
Gwatipedza said tests indicate that the water from borehole in the three suburbs is not safe for drinking.
Meanwhile, the council has set a treatment centre at Mkoba Polyclinic where people can be treated for free.
The council has since dispatched teams to create awareness about the outbreak to residents of Mkoba.
The local authority is continuing with investigations so as to establish the source of bacteria causing typhoid.
On Tuesday, the Minister of Health and Child Care is expected to visited the affected areas.
