A Zimbabwean man found to have cholera has sparked fears of an outbreak in
The man was allegedly kept at the Lindela Repatriation Camp before he was deported to
Limpopo MEC [Member of the Executive Council] for health Norman Mabasa confirmed 17 Mar 2013 the 1st tests conducted on the man had discovered _V. cholerae_. He said they were working very hard to establish the facts surrounding the man's illness.
"We are worried about the possibility of a cholera outbreak." He said a team from the provincial department would work with the national response team "to guide us on curbing the outbreak".
An influx of migrants from the countryside into the
"Heavy rain in the port city in recent weeks and sanitation problems triggered the cholera outbreak," said Health Minister Francois Ibovi.
According to the mayor of Pointe-Noire, Roland Bouiti Viaudo, the booming city has seen a large influx of migrants from rural areas. "People build and settle in prohibited areas, including [around] sewers, blocking the free flow of wastewater, which explains the repeated outbreaks of cholera," he told IRIN. "To stop the disease...
everyone -- the authorities, NGOs and communities -- should mobilize and become aware of this danger."
In early March 2013, during a council of ministers' meeting, the government announced that emergency aid had been released to combat the outbreak, but it did not specify the amount.
Health authorities in Pointe-Noire, a city of more than 800 000, have set up an intensive cholera treatment centre on the grounds of the 200-bed
347 have already returned home, 10 have died, and 32 are still hospitalized," he said.

Fri 15 Mar 2013, was the 200th anniversary of the birth of John Snow, an early epidemiologist who discovered contaminated water as the source of cholera in 1854. The following is a discussion of the discovery:
How often does a map change the world? In 1854, one produced by Doctor John Snow, altered it forever.
In the world of the 1850s, cholera was believed to be spread by miasma in the air, germs were not yet understood, and the sudden and serious outbreak of cholera in
There were some outliers though and Snow wrote that: In some of the instance, where the deaths are scattered a little further from the rest on the map, the malady was probably contracted at a nearer point to the pump."
One 59-year-old woman sent daily for water from the
At a local brewery, the workers were allowed all the beer they could drink -- it was believed they didn't drink water at all. But it had its own water supply too and there were consequently fewer cases.
It turned out that the water for the pump was polluted by sewage from a nearby cesspit where a baby's nappy contaminated with cholera had been dumped. But Snow didn't just produce a map; it was one part of a detailed statistical analysis.
As the Public Health Perspectives blog says, it changed how we see data visualisations, and how we see microbes. Snow was born 200 years ago (15 Mar 1813) and is the subject of an exhibition at the London School of Hygiene and Tropical Medicine.
