Sudan's acting health minister Al-Fateh Mohammed Saeed, however, said his ministry had been on alert for signs of the disease three weeks before an outbreak was declared and that the situation was now "quite stable".
According to a 14 November WHO update, 12 people died over a seven-day period in While Nile, Sinnar and Gezira States, and the number of reported cases of the disease increased to 329 from 228 a week before.
