Hotspots play a central role in the spread of disease to other areas. (Source – Cholera surveillance definitions – GTFCC) Cholera Hotspot • Use recent cholera data - at least last 5 years mapping - • Mapping cholera hotspots by district level GTFCC guidance – Incidence and mortality by hotspot • Description of contextual factors that favor cholera transmission in the hotspots • Review local capacities for implementing control interventions (incl. finances, surveillance, patient care, WASH, ability to conduct OCV campaigns) • Cholera line list data used South – Annual cholera attack rates by county Sudan – Annual cholera CFR Hotspot by county Microsoft Excel Worksheet mapping – – Assessment of high- risk groups in hotspot data used areas –Context and capacities assessed Cases/10,000 (2014) Cases/10,000 (2015) Cases/10,000 (2016) Cases/10,000 (2017) Renk Mayom Tonj North Nyirol Yirol West Tonj East Fashoda Yirol East Cholera Ayod Terekeka Manyo Hotspot - Mundri East Panyikang Yei analysis Magwi Lopa/Lafon Ikotos Torit output Fangak Mayendit Duk Canal Pigi Awerial Panyijiar Rubkona Bor Budi Kapoeta East Kapoeta South Kapoeta North Kajo keji Malakal Juba - 50 100 150 200 0 50 100 150 200 0 50 100 150 200 0 50 100 150 200 Estimated Annual Incidence Rate per 10,000 population by county and year CFR (%) 2014 CFR (%) 2015 CFR (%) 2016 CFR (%) 2017 Yirol West Yirol East Tonj North Tonj East Terekeka Rubkona Renk Panyijiar Nyirol Mayom Mayendit Magwi Leer Kapoeta East Cholera Fashoda Fangak Duk Canal Pigi Hotspot - Bor Ayod Awerial analysis Mundri East Manyo Budi Kapoeta South Bor output Juba 3 PoC Kapoeta North Torit Malakal Juba South Sudan Magwi Tongping PoC Yei River Lopa-Lafon Kajo-Keji Ikotos 0 20 40 0 20 40 0 20 40 0 20 40 60 Estimated CFR by county and year.

Weak social services sector – Health & Water 2. Development funding still low & hence no progress on implementing long term WASH interventions for cholera prevention 3. Inadequate integration of WASH in OCV campaigns 4. Sub-optimal involvement of other sectors 5. Access constraints - security, rainy season NEXT STEPS • Conduct an assessment of WASH needs that will be used to update the situation analysis and tailored WASH interventions in the NCCP • Review, update, validate, cost & launch the National Cholera Control Plan for South Sudan that is aligned to the Global Roadmap for cholera elimination by 2030 AKNOWLEDGEMENTS South Sudan Ministry of Health Pool Fund Health USAID/IOM Rapid Response UNOCHA – South Sudan Fund UNICEF GAVI Health Cluster partners GTFCC – Global Taskforce on Cholera Control WHO Thank you.
