"Emergency drugs and rehydration fluids have been provided,", he said, adding that the outbreak has been put under control.
World Health Organisation physician Sylvester Malemi said his agency would provide technical support to the state to tackle the outbreak.
He advised residents of the affected areas to boil their water before drinking and maintain good hygiene.
Cholera, a highly contagious intestinal infection, is transmitted by water soiled by human waste. The disease leads to diarrhoea, dehydration and death if untreated.
