Yemen cholera epidemic 'controlled' by computer predictions
Cholera cases in Yemen have been slashed by a new system that predicts where outbreaks will occur. Last year, there were more than 50,000 new cases in just one week - this year, the numbers plummeted to about 2,500. The system has enabled aid workers to focus efforts on prevention several weeks in advance of an outbreak - by monitoring rainfall. It comes as the UN says it is concerned about a possible "third wave" of the epidemic. The deployment of the technology has been coordinated by the UK's Department for International Development.
