A British charity insisted on Thursday, just hours after the country's President Robert Mugabe said there was no cholera in his country that Zimbabwe's Cholera outbreak is worsening.
The comments also came as the United Nations said the death toll from the outbreak had risen to 783, with 16,403 suspected cases.
Advertisement"If anything is certain in the chaos of Zimbabwe today it is that the cholera outbreak is not under control," said Save the Children's director for Zimbabwe Rachel Pounds.
She added: "Reliable figures are hard to come by, but there is much evidence out there that this crisis is growing, not diminishing, especially as we know there are many people who can't get to cholera centres."
"Given that this is a disease spread by unclean water and exacerbated by hunger which weakens victims, this problem has clearly not gone away. Water and health services have collapsed and more than half the 10 million population needs emergency food aid," she said.
"This deadly disease will continue to spread unless we get more money and more resources to halt the contamination and treat victims promptly."
Earlier Thursday, Mugabe said in a nationally televised speech: "I am happy to say our doctors have been assisted by others, and WHO (the World Health Organization) and they have now arrested cholera."
He also denounced calls by Prime Minister Gordon Brown of former colonial power Britain, French President Nicolas Sarkozy and US President George W. Bush for him to step down.
