Conditions ripe for diseaseThe resurgence of cholera in Sudan has been fuelled by heavy rains and flooding, overcrowding and lack of access to clean water in displacement sites and within communities. In certain localities in West Darfur, the case fatality rate has been as high as 11.8 per cent, she said. Ms. Khudari explained that WHO and partners have been working to control the outbreak with a vaccination campaign in the worst-hit communities. The WHO representative said that the “biggest challenge” in launching the campaign was to “actually get the vaccines there”. Access to life-saving treatment for cholera in Sudan is limited as the almost two-and-a-half-year-old violent conflict has devastated the health system.
