Sustainable strategies for Ebola virus disease outbreak preparedness in Africa: a case study on lessons learnt in countries neighbouring the Democratic Republic of the Congo.

BACKGROUND: From May 2018 to September 2022, the Democratic Republic of Congo (DRC) experienced seven Ebola virus disease (EVD) outbreaks within its borders. During the 10th EVD outbreak (2018-2020), the largest experienced in the DRC and the second largest and most prolonged EVD outbreak recorded globally, a WHO risk assessment identified nine countries bordering the DRC as moderate to high risk from cross border importation. These countries implemented varying levels of Ebola virus disease preparedness interventions. This case study highlights the gains and shortfalls with the Ebola virus disease preparedness interventions within the various contexts of these countries against the background of a renewed and growing commitment for global epidemic preparedness highlighted during recent World Health Assembly events. MAIN TEXT: Several positive impacts from preparedness support to countries bordering the affected provinces in the DRC were identified, including development of sustained capacities which were leveraged upon to respond to the subsequent coronavirus disease 2019 (COVID-19) pandemic. Shortfalls such as lost opportunities for operationalizing cross-border regional preparedness collaboration and better integration of multidisciplinary perspectives, vertical approaches to response pillars such as surveillance, over dependence on external support and duplication of efforts especially in areas of capacity building were also identified. A recurrent theme that emerged from this case study is the propensity towards implementing short-term interventions during active Ebola virus disease outbreaks for preparedness rather than sustainable investment into strengthening systems for improved health security in alignment with IHR obligations, the Sustainable Development Goals and advocating global policy for addressing the larger structural determinants underscoring these outbreaks. CONCLUSIONS: Despite several international frameworks established at the global level for emergency preparedness, a shortfall exists between global policy and practice in countries at high risk of cross border transmission from persistent Ebola virus disease outbreaks in the Democratic Republic of Congo. With renewed global health commitment for country emergency preparedness resulting from the COVID-19 pandemic and cumulating in a resolution for a pandemic preparedness treaty, the time to review and address these gaps and provide recommendations for more sustainable and integrative approaches to emergency preparedness towards achieving global health security is now.

Coordination mechanisms for COVID-19 in the WHO Regional office for Africa.

AIM: This study describes the coordination mechanisms that have been used for management of the COVID 19 pandemic in the WHO AFRO region; relate the patterns of the disease (length of time between onset of coordination and first case; length of the wave of the disease and peak attack rate) to coordination mechanisms established at the national level, and document best practices and lessons learned. METHOD: We did a retrospective policy tracing of the COVID-19 coordination mechanisms from March 2020 (when first cases of COVID-19 in the AFRO region were reported) to the end of the third wave in September 2021. Data sources were from document and Literature review of COVID-19 response strategies, plans, regulations, press releases, government websites, grey and peer-reviewed literature. The data was extracted to Excel file database and coded then analysed using Stata (version 15). Analysis was done through descriptive statistical analysis (using measures of central tendencies (mean, SD, and median) and measures of central dispersion (range)), multiple linear regression, and thematic analysis of qualitative data. RESULTS: There are three distinct layered coordination mechanisms (strategic, operational, and tactical) that were either implemented singularly or in tandem with another coordination mechanism. 87.23% (n = 41) of the countries initiated strategic coordination, and 59.57% (n = 28) initiated some form of operational coordination. Some of countries (n = 26,55.32%) provided operational coordination using functional Public Health Emergency Operation Centres (PHEOCs) which were activated for the response. 31.91% (n = 15) of the countries initiated some form of tactical coordination which involved the decentralisation of the operations at the local/grassroot level/district/ county levels. Decentralisation strategies played a key role in coordination, as was the innovative strategies by the countries; some coordination mechanisms built on already existing coordination systems and the heads of states were effective in the success of the coordination process. Financing posed challenge to majority of the countries in initiating coordination. CONCLUSION: Coordinating an emergency is a multidimensional process that includes having decision-makers and institutional agents define and prioritise policies and norms that contain the spread of the disease, regulate activities and behaviour and citizens, and respond to personnel who coordinate prevention.

Healthcare workers' experiences regarding scaling up of training on integrated disease surveillance and response (IDSR) in Uganda, 2016: cross sectional qualitative study.

BACKGROUND: The Integrated Disease Surveillance and Response (IDSR) strategy was adopted as the framework for implementation of International Health Regulation (2005) in the African region of World Health Organisation (WHO AFRO). While earlier studies documented gains in performance of core IDSR functions, Uganda still faces challenges due to infectious diseases. IDSR revitalisation programme aimed to improve prevention, early detection, and prompt response to disease outbreaks. However, little is known about health worker's perception of the revitalised IDSR training. METHODS: We conducted focus group discussions of health workers who were trained between 2015 and 2016. Discussions on benefits, challenges and possible solutions for improvement of IDSR training were recorded, transcribed, translated and coded using grounded theory. RESULTS: In total, 22/26 FGDs were conducted. Participants cited improved completeness and timeliness of reporting, case detection and data analysis and better response to disease outbreaks as key achievements after the training. Programme challenges included an inadequate number of trained staff, funding, irregular supervision, high turnover of trained health workers, and lack of key logistics. Suggestions to improve IDSR included pre-service and community training, mentorship, regular supervision and improving funding at the district level. CONCLUSION: Health workers perceived that scaling up revitalized IDSR training in Uganda improved public health surveillance. However, they acknowledge encountering challenges that hinder their performance after the training. Ministry of Health should have a mentorship plan, integrate IDSR training in pre-service curricula and advocate for funding IDSR activities to address some of the gaps highlighted in this study.

Evaluation of integrated disease surveillance and response (IDSR) core and support functions after the revitalisation of IDSR in Uganda from 2012 to 2016.

BACKGROUND: Uganda is a low income country that continues to experience disease outbreaks caused by emerging and re-emerging diseases such as cholera, meningococcal meningitis, typhoid and viral haemorrhagic fevers. The Integrated Disease Surveillance and Response (IDSR) strategy was adopted by WHO-AFRO in 1998 as a comprehensive strategy to improve disease surveillance and response in WHO Member States in Africa and was adopted in Uganda in 2000. To address persistent inconsistencies and inadequacies in the core and support functions of IDSR, Uganda initiated an IDSR revitalisation programme in 2012. The objective of this evaluation was to assess IDSR core and support functions after implementation of the revitalised IDSR programme. METHODS: The evaluation was a cross-sectional survey that employed mixed quantitative and qualitative methods. We assessed IDSR performance indicators, knowledge acquisition, knowledge retention and level of confidence in performing IDSR tasks among health workers who underwent IDSR training. Qualitative data was collected to guide the interpretation of quantitative findings and to establish a range of views related to IDSR implementation. RESULTS: Between 2012 and 2016, there was an improvement in completeness of monthly reporting (69 to 100%) and weekly reporting (56 to 78%) and an improvement in timeliness of monthly reporting (59 to 93%) and weekly reporting (40 to 68%) at the national level. The annualised non-polio AFP rate increased from 2.8 in 2012 to 3.7 cases per 100,000 population < 15 years in 2016. The case fatality rate for cholera decreased from 3.2% in 2012 to 2.1% in 2016. All districts received IDSR feedback from the national level. Key IDSR programme challenges included inadequate numbers of trained staff, inadequate funding, irregular supervision and high turnover of trained staff. Recommendations to improve IDSR performance included: improving funding, incorporating IDSR training into pre-service curricula for health workers and strengthening support supervision. CONCLUSION: The revitalised IDSR programme in Uganda was associated with improvements in performance. However in 2016, the programme still faced significant challenges and some performance indicators were still below the target. It is important that the documented gains are consolidated and challenges are continuously identified and addressed as they emerge.

The design and implementation of the re-vitalised integrated disease surveillance and response (IDSR) in Uganda, 2013-2016.

BACKGROUND: Uganda adopted and has been implementing the Integrated Disease Surveillance (IDSR) strategy since 2000. The goal was to build the country's capacity to detect, report promptly, and effectively respond to public health emergencies and priorities. The considerable investment into the program startup realised significant IDSR core performance. However, due to un-sustained funding from the mid-2000s onwards, these achievements were undermined. Following the adoption of the revised World Health Organization guidelines on IDSR, the Uganda Ministry of Health (MoH) in collaboration with key partners decided to revitalise IDSR and operationalise the updated IDSR guidelines in 2012. METHODS: Through the review of both published and unpublished national guidelines, reports and other IDSR program records in addition to an interview of key informants, we describe the design and process of IDSR revitalisation in Uganda, 2013-2016. The program aimed to enhance the districts' capacity to promptly detect, assess and effectively respond to public health emergencies. RESULTS: Through a cascaded, targeted skill-development training model, 7785 participants were trained in IDSR between 2015 and 2016. Of these, 5489(71%) were facility-based multi-disciplinary health workers, 1107 (14%) comprised the district rapid response teams and 1188 (15%) constituted the district task forces. This training was complemented by other courses for regional teams in addition to the provision of logistics to support IDSR activities. Centrally, IDSR implementation was coordinated and monitored by the MoH's national task force (NTF) on epidemics and emergencies. The NTF and in close collaboration with the WHO Country Office, mobilised resources from various partners and development initiatives. At regional and district levels, the technical and political leadership were mobilised and engaged in monitoring and overseeing program implementation. CONCLUSION: The IDSR re-vitalization in Uganda highlights unique features that can be considered by other countries that would wish to strengthen their IDSR programs. Through a coordinated partner response, the program harnessed resources which primarily were not earmarked for IDSR to strengthen the program nation-wide. Engagement of the local district leadership helped promote ownership, foster accountability and sustainability of the program.
