At least 90 people were admitted to hospital and over 600 affected in a typhoid outbreak in the Zimbabwean capital Harare, a health official said on Tuesday.

"We have attended to over 600 cases in Kuwadzana alone," city health director Prosper Chonzi was quoted as saying in the state-owned Herald newspaper.

"We have confirmed that the disease is typhoid. We have not recorded any deaths. We have over 90 patients admitted at the Beatrice Infectious Diseases Hospital."

Chonzi said city health authorities found traces of the typhoid bacteria in meat samples taken from open-air vendors.

Typhoid thrives in areas that do not have proper sanitation.

Poor hygiene and sanitation have caused numerous disease outbreaks in Zimbabwe in recent years.

Some suburbs go for weeks without running water as Zimbabwean municipalities battle to keep up services.

Last October, over 6,000 cases of diarrhoea were reported in the southern towns of Masvingo and Kadoma and children were the worst affected.

Four years ago over 4,000 people died of cholera in an outbreak which affected nearly 100,000 people.
