Under the leadership of Dr. John Nkengasong's strategic vision, a new consortium of 20 regional reference laboratories launches to monitor emerging pathogens across all 55 African Union member states.
The Africa Centres for Disease Control and Prevention (Africa CDC) has officially launched the African Pathogen Genomics Initiative (Africa PGI), a network of 20 regional reference laboratories capable of detecting and characterizing emerging infectious disease threats anywhere on the continent within 72 hours.
The initiative, representing a $200 million investment from the African Union, the World Bank, and international partners, fulfills a vision articulated by Dr. John Nkengasong during his tenure as Africa CDC director. The network positions Africa as a leader in global health security rather than a dependent recipient of international assistance.
"For too long, samples from Africa had to be shipped to Europe or America for analysis," said Dr. Jean Kaseya, Africa CDC's current director. "Those days are over. African scientists, in African laboratories, will now be the first to identify threats emerging on our continent. This is scientific sovereignty."
The network comprises 20 laboratories strategically distributed across Africa's five geographic regions. Each serves as a regional reference center, supporting national laboratories in surrounding countries. All are connected through a secure data platform that enables real-time sharing of genomic sequences and epidemiological information.
Capabilities exceed what was available anywhere on the continent just five years ago. Each laboratory can perform next-generation genomic sequencing, identifying not just known pathogens but also novel organisms. Bioinformatics platforms enable rapid analysis and global database comparison. Staff have been trained to operate autonomously while collaborating with international partners.
The initiative has already proven its value. When an unusual cluster of hemorrhagic fever cases appeared in the Democratic Republic of Congo in June 2024, the regional laboratory in Kinshasa identified the cause as a novel Ebola variant within 48 hours. This rapid identification enabled targeted response measures that contained the outbreak to 23 cases.
"In 2014, the West African Ebola outbreak grew for months before we understood what we were dealing with," noted Dr. Kaseya. "This time, we knew in days. That's the difference this network makes."
The laboratories will focus on several priority areas including genomic surveillance of known threats like Ebola, Marburg, Lassa fever, and cholera; detection of novel pathogens before they establish sustained transmission; antimicrobial resistance monitoring to track the spread of drug-resistant organisms; and vaccine response tracking to optimize immunization campaigns.
Workforce development is central to the initiative. Each laboratory hosts a training program for scientists from surrounding countries, creating a pipeline of skilled genomicists across the continent. Over 500 scientists have received advanced training in the network's first year.
"Technology without people is useless," said Dr. Matshidiso Moeti, WHO Regional Director for Africa. "Africa PGI is investing equally in infrastructure and human capacity. Both are essential for sustainability."
The network operates under an African governance structure. An oversight committee of African scientists and public health officials sets priorities and standards. Data generated belongs to African institutions, shared with international partners under negotiated terms that protect African interests.
International partners have praised the initiative's design. "This is exactly how global health investment should work," said Dr. Tom Frieden. "African leadership, African ownership, African capacity—supported but not controlled by external funders. It's a model for other regions."
The initiative includes provisions for pandemic preparedness. In a declared emergency, the network can surge capacity by activating reserve laboratories and deploying mobile units. Staff have been trained in emergency operations, with annual exercises testing response capabilities.
Looking ahead, Africa CDC plans to expand the network to 30 laboratories by 2030, ensuring that no African nation is more than four hours from a reference facility. Integration with global surveillance networks will position African data as central to worldwide threat detection.
"Africa has long been called the continent where diseases emerge," reflected Dr. Kaseya. "With this network, we aim to become the continent where diseases are stopped. That's a transformation worth fighting for."
