Young prostitutes appear to be organized into groups led by a elder women who smuggles the girls here from Zimbabwe, says Ushe Nyahunzvi, a man from Zimbabwe who works at the Hillbrow Inn.
"These [elder] women are the ones who smuggle them from their native countries for the purposes of using the girls to make a living. Old women are losing business hence using the girls," Mr. Nyahunzvi says. "The competition is very tight because of the World Cup."
Cyril Mwamba, 32, says she traveled more than 1,700 miles from Zambia's Ndola Copperbelt to reach the World Cup. Along the way, she met up with Zimbabwean prostitutes at a bus station, and she says they decided to travel together to Johannesburg for the opportunities here.
"When we came here [Summit Hotel], we were not so sure whether we would be able to attract rich and well-paying men since back home in Zambia men were looking down upon us," she says. She says she now earns R2,000 (about $270) per night.
"I am convinced that after the World Cup, I will be able to buy my own car," Ms. Mwamba says. "Cars are cheap here in South Africa."
While South African officials have long had difficulty keeping out illegal immigrants, South Africa’s Department of Home Affairs says it has tightened its borders to prevent human trafficking during the World Cup.
