The IRC responds to the world’s worst humanitarian crises and helps people whose lives and livelihoods are shattered by conflict and disaster to survive, recover, and gain control of their future. IRC was founded in 1933 through the advice of Albert Einstein to respond to the needs of people vulnerable to conflict around the world. Since then, it has expanded and evolved to become one of the world’s leading humanitarian organisations. In 2016, more than 26 million people benefited from IRC programs and those of its partner organizations.

There is persistent transmission of Hepatitis E Virus (HEV) in Bentiu Internally Displaced Population (IDP) camp in Rubkona County, Unity State, South Sudan. Cumulatively 2237 cases have been reported since beginning of 2019 when the outbreak was declared with 18 deaths reported cumulatively (Case Fatality Rate; 0.8%). There has been an upsurge of cases in the camp in the first half of 2021 due to reduced WASH in the camp due to funding constraints. HEV transmission has increased from a peak of 53 cases every fortnight by week 28 2021 to 67 cases every fortnight by week 10 2022.

As per January 2022 head count, Bentiu IDP camp hosts over 107,390 people and is divided into five sectors (sector 1=13,642, sector 2=18,853, sector 3=28,163, sector 4=19,508 and sector 5=27,224) HEV cases are reported from all sectors, highlighting widespread transmission. However, sector specific attack rates for HEV disease for 2022 are the highest in sectors 3 and 5. This is concerning particularly due to continued expected population movement into the IDP camp due to insecurity, subnational conflict, and seasonal flooding.

Purpose of Endline Evaluation:

This outbreak and HEV continued transmission has exposed the need for more efforts to scale up preparedness and response activities, drawing from available evidence and learning generated from ongoing responses. This endline evaluation will assess the hepatitis E Virus outbreak response interventions in Bentiu IDP camp assessing epidemiological and Environmental factors in Bentiu IDP Camp to identify the source of infection, mode of spread and other risk factors for Hepatitis E Virus infection. The scope of post action review will be focused on the public health response to HEV response. The evaluation will identify best practices and document lessons learned to inform HEV responses in camp settings.

Objectives of the Endline Evaluation:

This final evaluation exercise will seek to achieve the following objectives:

1. To critically review current methods for the detection, identification, characterization, and tracing of HEV. In the case of methods for detection, special emphasis should be made to assess their application to samples from food-producing animals and foods.

2. To examine currently available information on the geographical distribution of HEV and epidemiology, occurrence and persistence in foods and consumer habits contributing to infection.

3. To assess response measures in place (Health, WASH, Environmental Health) and possible control, management and prevention measures along the food chain and evaluate decontamination treatments.

4. Document good practices and lessons learned supported by evidence from current and past HEV response interventions in Bentiu IDP camp.

Endline Evaluation Scope:

The consultant will conduct end line evaluation in all sectors of Bentiu IDP camp. The survey team members and shall conduct the endline evaluation to the required quality standards.
