The authorities have yet to isolate the source of cholera that killed two residents of Soweto, South Africa's largest township, on the southwestern fringe of Johannesburg, but the community is blaming local government's failure to provide basic services like clean water and proper sanitation.

Earlier this month the Department of Health in Gauteng Province confirmed that two people living in the Chicken Farm informal settlement in Kliptown, an area in Soweto, had died after contracting the waterborne disease.

"The source of the infection has not been established, but an urgent investigation is underway to establish the source, identify and treat possible cases, and ensure no further spread of this illness," a spokesperson for the provincial health department, Zanele Mngadi, told IRIN.

Cholera is an intestinal infection causing acute diarrhoea and vomiting and, if left untreated, can cause death from dehydration within 24 hours. It is easily treatable with rehydration salts.

Deeper issues

Soweto residents point to deep-seated problems related to poor sanitation facilities and the lack of access to potable water. Patra Findane, national organiser for the Coalition Against Water Privatisation (CAWP), a pressure group agitating for free water for all in Soweto, said many more Kliptown residents were showing symptoms associated with cholera. Findane said there had been unconfirmed reports of a third case this week.

A joint statement by CAWP and the Kliptown Concerned Residents (KCR) read: "While it is a shock to everyone in the community to lose one of its members, it should not be a surprise ... the government's neglect of pleas for emergency intervention to combat the social and environmental crisis makes it fully responsible for her death." The statement was issued after members of the groups had visited the family of one of the two confirmed cases of cholera.

"Residents live in fear as they wonder who is next," the statement commented. "Despite all efforts undertaken by the poor residents of Kliptown to get its attention, the City continues to turn a blind eye."

Findane said local government's failure to adequately improve basic services delivery to a neglected township that is more than 100 years old had likely been the main contributing factor to the outbreak of the disease.

The informal settlements of Soweto have no sewage or drainage systems and the bucket system of human waste disposal is still widely used, despite promises by the government that the practice would be eradicated by the beginning of 2007.

Failing to isolate the source

Last week Johannesburg Water, the local utility, said the results of recent tests of the area's water supply confirmed that Kliptown's water was cholera-free and safe to drink.

Municipal spokesperson Baldwin Matsimela said the City of Johannesburg's Environmental Management System, which is part of Johannesburg Water and is responsible for sampling and monitoring surface water, took samples in Kliptown on 28 March and 8 April.

The samples tested negative for cholera on both occasions, and more samples were taken on 11 April but tests on these were also reported as negative for cholera.

"In addition, drinking water samples were taken from the informal settlement in the Kliptown area and the results were cleared of any contamination," Matsimela said.

Findane doubted this. "They say there is no cholera here, but all over Kliptown there are posters and field-workers from different local clinics warning people about the threat of cholera infection. So why should we believe the current cholera outbreak has nothing to do with terrible conditions the people live in, and that it is not a big problem?" he asked.

The CAWP has called on the Department of Water Affairs and Forestry, the Department of Health and Johannesburg Water "to immediately act on the crisis in Kliptown. Without water and sanitation more people will continue to fall ill in this community."
