Early Warning and Disease Surveillance System Republic of South Sudan EARLY WARNING AND DISEASE SURVEILLANCE BULLETIN (IDP CAMPS AND COMMUNITIES) Week 43 20 October – 26 October 2014 General Overview Completeness for weekly reporting increased from 66% to 82% while timeliness increased from 36% to 54% in week 43 when compared to week 42. Malaria remains the top cause of morbidity with Malakal, Tongping, UN House, Renk, and Melut reporting the highest incidence in week 43. Malakal PoC had the highest incidence for Malaria, ARI, AWD, and ABD during week 43; highlighting the need to enhance communicable disease prevention and control interventions in the PoC. Sixteen measles cases were reported from Melut (11 cases), Lankien (4 cases), and Mingkaman (1 case). One new probable HEV case was reported in Bentiu PoC in week 43. The cumulative for HEV is 113 cases and 4 deaths (CFR 3.7%) after one new case was reported from Mingkaman in week 43. Forty seven cholera cases and two deaths were reported from Lobonok in Juba, Central Equatoria State, as well as Lofus, Lorum and Imatong in Ikotos County; Ohilang and Ibele in Lopa-Lafon County; and Kapoeta South Town in Eastern Equatoria State in week 43. The cumulative stands at 6,297 cases with 160 deaths (CFR 2.26%). Kala-azar trend continues to surge to its seasonal peak with 5,713 cases and 163 deaths reported this year. The under-five and crude mortality rates in all IDP sites were below the emergency threshold in week 43. Completeness and Timeliness of Reporting Completeness for weekly reporting increased from 33 (66%) in week 42, to 41 (82%) in week 43. Timeliness for weekly reporting increased from 18 (36%) in week 42 to 27 (54%) in week 43.

Three outreach sites including Yalakot mobile (IMC), Panculim mobile (IMC), and Man-Awan (Goal) were not visited but zero reports were submitted. Health facilities are requested to kindly submit their IDP reports for the preceding week, by 17:00 hrs on Monday.

During week 43, most of the consultations were reported from Malakal, Renk, Awerial, Melut, UN House, and Bentiu (Figure 2). Figure 2 Overall Trends of Priority Epidemic-prone Diseases Figures 3 and 4 show the proportionate and incidence morbidity trends for Acute Respiratory Infection (ARI), Malaria, Acute Watery Diarrhoea (AWD), suspected measles and Acute Bloody Diarrhoea (ABD) in the IDP sites and communities. Malaria, ARI and AWD were the top three causes of morbidity among IDPs in week 43 (Figure 3 and 4). During week 43, malaria had the highest proportionate morbidity and incidence when compared to the other top five causes of morbidity among IDPs (Figure 3 and 4). The overall incidence for malaria, ARI, ABD, AWD, and suspected measles increased in week 43 when compared to week 42 (Figure 4). This Bulletin is produced by MOH, RSS with Technical support from WHO 2 Early Warning and Disease Surveillance System Figure 3 The weekly number of cases for the current and preceding weeks, and cumulative number of cases for the top five causes of morbidity are presented in Table 2.

ARI registered the second highest proportionate morbidity of 18.6% and incidence (52 cases per 10,000 population) in week 43 (Figure 5). Figure 5 During week 43, a total of 2941 cases of ARI were reported with the highest ARI incidence (cases per 10,000) being reported in Malakal (984), UN House (270), Bor (46), Bentiu (46), and Akoka (44). Acute Watery Diarrhoea As seen from Figure 6, the AWD proportionate morbidity increased from 5.9% to 6.8% and the overall AWD incidence (cases per 10,000) increased from 14 to 19 in week 43 when compared to week 42 (Figure 4). Overall, the AWD trend has been on the decline since the beginning of the year. Figure 6 This Bulletin is produced by MOH, RSS with Technical support from WHO 4 Early Warning and Disease Surveillance System During week 43, a total of 1068 AWD cases were reported with the highest AWD incidence (cases per 10,000) being reported in Malakal (120), Melut (78), UN House (52), Renk (44) and Akoka (37) as illustrated in Figure 7).

The incidence (cases per 10,000) of AWD is higher in children under five years of age. The high AWD incidence during weeks 17-25 corresponds to the peak of the cholera outbreak in South Sudan. These trends indicate that the background risk for acute watery diarrhoea is high especially in children under-five.

The overall ABD trend has been on the decline since the beginning of the crisis with successively shorter peaks in weeks 2, 21, and 37. The incidence (cases per 10,000) of ABD increased from 2 to 4 while the proportionate morbidity (%) increased from 1.0 to 1.4 in week 43 when compared to week 42. Figure 9 shows ABD incidence trends by IDP site from week 1 to week 43 in 2014. During week 43, the highest ABD incidence was reported in Malakal PoC as compared to other IDP sites. During week 43, 218 ABD cases were reported with the highest ABD incidence (cases per 10,000) being reported in Malakal (21), Renk (19), Melut (14), Akoka (Rom) (12), and Ogod (9). This Bulletin is produced by MOH, RSS with Technical support from WHO 5 Early Warning and Disease Surveillance System Figure 8 These ABD trends highlight the need to improve access to safe drinking water and sanitation facilities in all IDP camps. Stool samples should be obtained from suspected cases to facilitate laboratory testing. Laboratory confirmation will allow better clinical case management and the initiation of tailored public health interventions.

This trend is attributed to a series of reactive measles vaccination campaigns conducted to contain the outbreaks in UN House, Tongping IDP camp, Bor, Yuai, Lankien, Cueibet and in Thol Payam, Nyirol County in Jonglei State.
