A total of 75, 8 people displaced by violence since December 213 within South Sudan, and over 2, displaced in to the neighboring countries (UNOCHA). A total of 1 sites (66.7%) reported in week 9 compared to 11 sites (73%) in week 8. Measles outbreak is declining in all the major IDP sites that reported cases in the previous weeks. Suspected meningitis cases reported in Juba III IDP camp, Kajo Keji County and Abyei County. The 5 days OCV immunization campaign in Tongping IDP camp (Juba) ended on Tuesday 4th March, a total of 14,112 were vaccinated in round one. The 7 days OCV immunization campaign in Mingkoman camp (Awerial) ended on Tuesday 4th March, a total of 52,398 were vaccinated in round one. 2. Trends of priority diseases (cases) in IDP Camps, week 51 to week 9 The figure1 below shows the trends of acute bloody diarrhea, malaria, suspected measles, and acute watery diarrhea in the IDP camps. A general decline is observed in the last two weeks Trend for ABD, AWD and Malaria are likely to change with the onset of rains expected in April Figure 1: Trends of Priority Diseases in IDP camps Wk Wk WK 1- WK 2- WK 3- WK 4- WK 5- WK 6- WK 7- WK 8- Bloody Diarrhoea Malaria Suspected Measles Watery diarrhoea WK 9- For comments or questions, please contact Surveillance Department, MoH-RSS outbreak_ss_27@yahoo.com, HF radio frequency: 815 USP; CELL CALL: 72 1

5 4. 5 suspected meningitis cases Meningitis outbreak was confirmed in South Sudanese refugee camps in Northern Uganda. As of 27 th Feb 19 cases reported among refugees in Arua (3/34=8.8%) and Adjumani (16/41=39%). Cumulative total of 7 suspected meningitis cases and five deaths (CFR=71.4%) have been reported from Kapoeta North and Budi counties of Eastern Equatoria state. Culture results from AMREF were negative for Neisseria meningitides. No additional cases in week 9 Cumulative total of 8 suspected meningitis cases and 2 deaths (CFR= 25%) have been reported from Kajo Keji county in Central Equatoria State. The latest two cases were reported in week 9 and 1. Cumulative total of 27 suspected cases have been reported from Aweil Civil Hospital in Northern Bahr el ghazal state between week 1 and 8.

Mortality data 5.1 Under-five mortality rate The under-five mortality rate in all IDP camps have come down below the emergency threshold (U5MR: 2 per 1, per day) as of week 9 (figure 9).

Oral Cholera Vaccination (OCV) The 5 days OCV immunization campaign in Tonping IDP camp (Juba) ended, a total of 14,112 were vaccinated in round one. The 7 days OCV immunization campaign in Mingkoman camp (Awerial) ended on Tuesday 4th March, a total of 52,398 were vaccinated in round one. Round one OCV campaign in Juba III will start on Monday. Social mobilization will be done 2 days prior the campaign. There were disparities between the OCV final tally figures and the used vials MoH/WHO teams are supporting the vaccination monitoring process 7. Conclusions Despite reduction in morbidity in most IDP camps, the trends for diarrhoea diseases and malaria are likely to change due to the onset of rains expected in April. Measles outbreak at its tail end in the IDP camps. A threat of meningitis outbreak is real, local laboratory capacity for confirmation is lacking. The country is currently having stocks of about 9, doses of trivalent (A/C/W135). 8. Recommendations 8.1 Standing recommendations Integrated health services should Improve and expanded in all IDP camps Ensure timely and good quality of morbidity and mortality data from all IDP camps including line listing of all suspected cases of measles using the standard line list. Strengthen disease surveillance system for timely detection, reporting and response to outbreaks and other public health events Fast track importation and distribution of pharmaceutical and none pharmaceuticals to avert a looming crisis in some states. Scale up the use of oral cholera vaccination in other camps (Bor, Malakal and Bentiu) as an additional public health tool to compliment the ongoing WASH activities. Vaccination of new arrivals and routine immunization in camps to prevent future outbreaks. Measles specimens to be analyzed in Juba after the laboratory were re-established. 8

9 Strengthen capacity for meningitis specimen collection, packaging and transportation in order to improve the isolation rate. Logistical and financial resources should be mobilized to undertake a preventive meningitis mass vaccination in the high risk areas. Improve on cross border surveillance by sharing epidemiological information with neighbouring countries that have received influx of refugees from South Sudan. Use the shared WHO South Sudan crisis response proposal to mobilize funds at all levels. 8.2 Additional recommendations Use lessons learnt after 1 st round OCV campaign in Tongpin and Mingkaman to improve the quality of the planned Juba III campaign which is starting on Monday. Despite the OCV campaigns, laboratory surveillance using cholera RDT kits is required for early detection of cholera cases. The early warning mechanism is critical with the expected rains and floodings.
