The outbreak of cholera in Darwin has claimed three people in three days, the official said.
Mt Darwin District Nurse Anna Chinyemba confirmed her death
Sister Chinyemba said the first victim died on Sunday, while the other two yesterday morning and evening in that order.
She said the people affected are workers from the Mukaradz Workers' Area, located 25 miles from Mt Darwin.
"We suspect that the outbreak could be due to poor hygiene because most of the mining activities taking place in the area are illegal," Sister Chinyemba told the press agency.
"The area is overburdened by craft miners and there is illegal sale there, and the area has no safe water sources, most of the people affected are men."
Yesterday, the World Health Organization announced that in Mt Darwin it is preparing a cholera treatment camp for strength.
