Abstract The East African Community (EAC) grapples with many challenges in tackling infectious disease threats and antimicrobial resistance (AMR), underscoring the importance of regional and robust ...pathogen genomics capacities. However, a significant disparity exists among EAC Partner States in harnessing bacterial pathogen sequencing and data analysis capabilities for effective AMR surveillance and outbreak response. This study assesses the current landscape and challenges associated with pathogen next-generation sequencing (NGS) within EAC, explicitly focusing on World Health Organization (WHO) AMR-priority pathogens. The assessment adopts a comprehensive approach, integrating a questionnaire-based survey amongst National Public Health Laboratories (NPHLs) with an analysis of publicly available metadata on bacterial pathogens isolated in the EAC countries. In addition to the heavy reliance on third-party organizations for bacterial NGS, the findings reveal a significant disparity among EAC member States in leveraging bacterial pathogen sequencing and data analysis. Approximately 97% ( n = 4,462) of publicly available high-quality bacterial genome assemblies of samples collected in the EAC were processed and analyzed by external organizations, mainly in Europe and North America. Tanzania led in-country sequencing efforts, followed by Kenya and Uganda. The other EAC countries had no publicly available samples or had all their samples sequenced and analyzed outside the region. Insufficient local NGS sequencing facilities, limited bioinformatics expertise, lack of adequate computing resources, and inadequate data-sharing mechanisms are among the most pressing challenges that hinder the EAC’s NPHLs from effectively leveraging pathogen genomics data. These insights emphasized the need to strengthen microbial pathogen sequencing and data analysis capabilities within the EAC to empower these laboratories to conduct pathogen sequencing and data analysis independently. Substantial investments in equipment, technology, and capacity-building initiatives are crucial for supporting regional preparedness against infectious disease outbreaks and mitigating the impact of AMR burden. In addition, collaborative efforts should be developed to narrow the gap, remedy regional imbalances, and harmonize NGS data standards. Supporting regional collaboration, strengthening in-country genomics capabilities, and investing in long-term training programs will ultimately improve pathogen data generation and foster a robust NGS-driven AMR surveillance and outbreak response in the EAC, thereby supporting global health initiatives.
Within the first 14 days after outbreak confirmation, the East African Community Mobile laboratory network was actively involved in providing Sudan virus disease and differential diagnostics in the ...epicentre at Mubende Regional Referral Hospital (and neighbouring districts), as well as in coordination of mobile laboratory preparedness activities in five other East African countries. Introduction On 20 September 2022, the Ugandan Ministry of Health declared an Ebola Sudan virus disease (SVD) outbreak in the Mubende District of the country, with one confirmed SVD death and six probable deaths reported in the region since 1 September 2022.1 Since 2017, and with funding from the German Federal Ministry for Economic Cooperation and Development through the KfW Development Bank, the East African Community (EAC) together with the Bernhard-Nocht-Institute for Tropical Medicine established a network of nine mobile EAC laboratories embedded within the National Public Health Laboratories (NPHLs) of six EAC Partner States (Tanzania, Kenya, Burundi, Rwanda, South Sudan and Uganda).2 3 These field-deployable mobile laboratories have the capacity to diagnose risk group four pathogens, such as SVD. On the same day of the SVD outbreak announcement (20 September 2022) by the Ugandan government, the EAC Health Department initiated their regional pandemic preparedness and response activities, which consisted of a two-pronged approach: while the mobilisation of the EAC mobile laboratory network commenced, the regional procurement of diagnostic kits for SVD and differential diagnosis was immediately initiated (for a detailed timeline of events, see table 1).Table 1 Timeline of regional SVD outbreak response and preparedness activities in six East African countries Days following outbreak announcement 1 2 3 4 5 6 7 8 9 10 11 12 13 14 SVD outbreak declared by Uganda MoH EAC secretariat Emergency pandemic preparedness meetings Emergency procurement initiated Logistical support (kit delivery) Technical country support Press Release No of SVD kits ordered/expected 1×96 tests (arrival day 20) Uganda SVD outbreak response Request for support to EAC Lab deployment from Kampala to Mubende Start of testing No of SVD kits ordered/received 4×96 tests No. Diagnostic workflows, standard operating procedures and supply of diagnostics kits The EAC Mobile laboratories consist of negative pressure gloveboxes (Könnecke, Germany) (see figure 2) for sample inactivation and Bio-Rad CFX96 RT-PCR platforms for molecular SVD diagnosis (for further details on the laboratory setup, see Affara et al2).
