Timely and efficient data transfer through the internet plays a critical role in establishing a real-time public health genomic surveillance system. However, limited bandwidth internet access remains a significant challenge in Africa, hindering the timely transfer of data and effective utilization of cloud-based or open-source web-based bioinformatics solutions and databases. To address this issue, the Africa PGI, in collaboration with ASLM, BMGF, and SpaceX, initiated a pilot project in September 2023. The primary objective of this project is to enhance access to high-speed satellite-based internet, enabling real-time, or near-real-time, transfer of pathogen genomic data and facilitating access to cloud-based resources. This high-speed internet service will not only improve data transfer but also enhance other internet-based operations such as communication, e-learning, virtual meetings, video conferences, and various other activities. The pilot project is being implemented in all Member States that have obtained regulatory approval for the operation of SpaceX’s satellite-based internet.

With the continuous expansion of the Africa CDC laboratory network, digital transformation becomes imperative to enhance efficiency. In November 2023, the Africa CDC introduced a laboratory network information management system (NIMS – https://www.pgi-nims-africacdc.org/) to monitor and facilitate informed decision-making on network operations. The NIMS system serves as a valuable resource for Africa CDC, centers of excellence, regional and national laboratories, enabling efficient tracking of biological sample shipments and ensuring their integrity during transit from referral sites to destination facilities across the network. This system also supports cross-border sample referrals for testing and sequencing. The NIMS system has undergone successful piloting for cross-border sample referral in four sites and is currently being implemented for in-country sample referral in one site. The integration of connectivity, digitization, and innovative solutions in public health genomics in Africa will contribute significantly to the detection, response, and control of infectious diseases. By strengthening genomics capacity, improving internet access, and digitizing laboratory operations, Africa is poised to harness the full potential of genomics for public health surveillance and outbreak management.

The post Digitizing public health genomics in Africa appeared first on Africa CDC.

The emergence and spread of drug-resistant malaria, mutated parasites that skip detection by commonly used rapid diagnostic tests, and the resurgence of malaria transmission in multiple countries are major threats to the control and ultimate elimination of malaria. A recent expansion of malaria genomics in Africa has enormous potential to help tackle these problems, but there is an urgent need to expand the workforce for the generation, analysis, interpretation and utilization of malaria molecular surveillance (MMS) data to fully realize this potential. To fill this gap, Africa CDC collaborated with IDRC, UCSF and JHU to develop and deploy an interactive, hands-on workshop, bringing together programmatic and research personnel to understand the uses of malaria genomics in augmenting public health surveillance, discuss the challenges in implementing such technology, and work together across institutions and countries to identity practical solutions.

“This training was a unique opportunity to bring together researchers and officers from the national malaria control program to support the expansion of malaria molecular surveillance to monitor the spread of drug and diagnostic resistance variants across Africa”, said Dr. Yenew Kebede, Head Division of Laboratory Systems and Networks and Acting Head of Division of Disease Surveillance and Intelligence at the Africa CDC. He further added, “The training will act as one of the avenues to bridge the gap between researchers who develop tools and generate data and the program officers who apply data to inform malaria control and elimination”.

“The knowledge and skills gained from this training workshop have the potential to further expand MMS in public health settings by facilitating networking and exchange of ideas between those working in programmatic and research settings.” said Bryan Greenhouse, Associate Professor and Co-director of the EPPIcenter program at the University of California, San Francisco.

“We hope that this training will inspire researchers and programs to work together to achieve the goal of integrating MMS into routine surveillance in their countries, with the longer-term goal of increased regional collaboration to prevent and respond to the spread of drug and diagnostic resistance,” said Jessica Briggs, Assistant Professor also from the University of California, San Francisco, who led development and delivery of the course.

The participants of this training were equipped with knowledge and skills required for the application of malaria genomic data for programmatic needs. The interactive modules in the present training workshop comprised of introduction to malaria epidemiology, molecular genomics, data management, bioinformatics and data analysis tools, translation of data into meaningful results, and ways to disseminate these results in multiple forums, along with the current state of high priority threats in the region. Trainers from the KEMRI-Wellcome Trust Research Programme in Kenya, the Armauer Hansen Research Institute (AHRI) in Ethiopia, and Brown University were also involved in the workshop.

The post Strengthening the Malaria Genomics Workforce in East Africa appeared first on Africa CDC.

The scientific publication includes over 300 authors from Africa and abroad who worked together to describe and analyze over 100,000 genomes and characterize SARS-CoV-2 variants in real-time. This was the largest consortium of African scientists and public health institutions working together to support data-driven COVID-19 response in Africa.

This publication shows how the large investment, collaboration and capacity building in genomic surveillance on the African continent enabled real-time public health response. Particularly it describes the setting up of the Africa Centre for Disease Control and Prevention (Africa CDC) – Africa Pathogen Genomics Initiative (Africa PGI) and the development of the continental network by the Africa CDC and the Regional Office for the World Health Organization in Africa (WHO) to expand access to sequencing and cover surveillance blind spots, in parallel with the growth of the number of countries that are able to sequence SARS-CoV-2 with in the country.

“The publication highlights that sustained investment for diagnostics and genomic surveillance in Africa was needed to not only combat SARS-CoV-2 on the continent, but establish a platform to address the emerging, re-emerging, endemic infectious disease threats, such as Ebola, HIV/AIDS, TB and Malaria. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century.” said Dr. Yenew Kebede, Head Division of Laboratory Systems Acting Head for Surveillance and Disease Intelligence at the Africa CDC

This study was led by two labs that setup the network for genomics surveillance in South Africa, the Centre for Epidemic Response and Innovation (CERI) at Stellenbosch University and the KwaZulu Natal Research and Innovation Sequencing Platform (KRISP) at the University of KwaZulu-Natal, in close coordination with the Africa CDC, WHO AFRO and 300 other institutions across the continent.

“The enormous leap Africa made in genomic surveillance during the past two years is the silver lining in the COVID-19 pandemic,” said Dr Matshidiso Moeti, WHO Regional Director for Africa. “The continent is now better prepared to face down both old and emerging pathogens. This is a model of how when Africans are in the driving seat we can come up with lasting change and stay a step ahead of dangerous diseases.”

“It has been an inspiring experience to share knowledge, support and learn from colleagues in all parts of the continent continuously during the pandemic. We witnessed small

countries with no previous genomics experience become empowered in sequencing and bioinformatics methods, and start to actively participate in regular pathogen genomic surveillance for SARS-CoV-2. I think it will be a real model of how scientists and public health officials across countries can have a unified front against infectious diseases in the future.”, says Houriiyah Tegally, Bioinformatician at KRISP and CERI and first-author on this publication.

The results also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most relevant being the detection of Beta and various Omicron subvariants. The publication highlights that most of the SARS-CoV-2 variants causing epidemic in Africa were introduced from abroad.

The scientists proceeded carefully in analysing genomic and epidemiological data collected in over 50 countries that experienced quite heterogenous epidemics in order to reconstruct transmission dynamics of the virus in the most accurate way. “The phylogeographic methods that we employ to investigate the movement of the SARS-CoV-2 virus and its variants into, out of, and within the African continent account for uneven testing and sampling proportions across countries, arising from the realities of doing genomic sequencing in the middle of a pandemic, often in low resourced settings.”, explains Dr. Eduan Wilkinson, head of bioinformatics at CERI at Stellenbosch University and senior author on this publication.

The initial waves of infections in Africa were primarily seeded by multiple introductions of viral lineages from abroad (mainly Europe). The Alpha variant that emerged in Europe in the end of 2020 ended up causing infections in 43 countries with evidence of community transmission in Ghana, Nigeria, Kenya, Gabon and Angola. For Delta, the bulk of introductions was attributed to India (~72%), mainland Europe (~8%), the UK (~5%), and the US (~2.5%). Viral introductions of Delta also occurred between African countries in 7% of inferred introduction. For Omicron the scientific results indicate more reintroductions of the variant back into Africa, at least 69 (95% CI: 60 – 78) from Europe and 102 (95% CI: 92 – 112) from North America than from other African countries. This was amplified for Omicron BA.2; the results suggest at least 99 separate introduction or reintroduction events of BA.2 into African countries, ~65% of which are from Europe and ~30% from Asia.

“The ironical part of these results is that most of the introductions of variants in Africa were from abroad, but Africa was the most discriminated and penalized continent in the world with travel bans. Instead of unscientific and inappropriate reactions, we should be building on the infrastructure established in Africa so that the continent can rapidly pivot to other epidemics without the fear of being punished” said Prof. Tulio de Oliveira, Director of the two institutes, CERI and KRISP, that lead the consortium analysis with the Africa CDC and WHO AFRO.

“This study is a testament to Africa CDC’s impact in rapidly expanding access to sequencing technologies by African Union Member States, and creating a platform for coordination and collaboration by all stakeholders.” said Dr. Ahmed Ogwell, Acting Director of the Africa CDC

The post A continent-wide collaboration on genomics surveillance show the power of African science and how the majority of COVID-19 variants were introduced into Africa appeared first on Africa CDC.

As part of its vision to integrate pathogen genomics into the public health surveillance and diseases outbreak response, the Africa CDC through the Africa Pathogen Genomics Initiative (Africa PGI) is collaborating with African Society for Laboratory Medicine (ASLM), WHO Regional Office for Africa, Centers of Excellence in genomics and bioinformatics to train a network of national public health laboratories in the generation and analyses of SARS-COV-2 genomic data. The goal of the training is to build skilled workforce that can provide rapid and representative genomic data to inform the continental COVID-19 pandemic response.

“With the ongoing emergence and spread of variants of concern, we need to increase sequencing capacity and build a critical mass of skilled human resources in the field of pathogen genomics and bioinformatics in Africa. We are pleased to partner with Centers of Excellence to develop and deliver training series to accelerate SARS-CoV-2 sequencing across the continent. The training at ACEGID will enable 12 Member States to expand their sequencing capacity” said Dr. John Nkengasong, the Director of Africa CDC.

“Our partnership with Africa CDC, WHO-AFRO is really remarkable, especially as we are able to bring together trainees from 12 African countries to this event.  Bringing together Academic, Public Health Institutions and the private sector, is definitely the beginning of a new public health era in Africa.  This training is a true testimonial of the Africa PGI and will increase the human capacity in genomics research in Africa. The training will contribute to increase the number of SARS-CoV-2 whole genome sequences in the continent and guide public heath interventions” said Prof. Christian Happi, Founder and Director of ACEGID, Redeemer’s University, Ede, Nigeria.

“Illumina believes strongly in the democratization of sequencing, such that all countries have access to genomics,” says Paula Dowdy, Senior Vice President and General Manager for Europe, Middle East and Africa, Illumina. “We are delighted to be supporting this training program with our cutting-edge technology because it will empower individual countries to drive pathogen surveillance according to their own needs.”

“Africa CDC will continue to work closely with the centers of excellence, the private sector, and other implementing partners to expand training on genomics and bioinformatics. The training organized at ACEGID is one step forward in this effort and more trainings will be organized in collaboration with other centers of excellence and regional hubs” said Dr. Yenew Kebede, Head, Division of Laboratory Systems and Networks at Africa CDC.
