A cholera outbreak that started in Blue Nile state in August 2016 began to spread rapidly as of April this year. Conservative estimates suggest a minimum of between 15,000-23,000 people infected, with 280-820 deaths. It is currently affecting Gedarif, White Nile, Khartoum, Sennar, River Nile, North Kordofan, and Gezira states. White Nile is host to a large South Sudanese refugee population and has had the highest number of cases so far. A state of emergency has not yet been declared and response has been limited. An underfunded health system and poor WASH facilities have contributed to the spread of infection.
