Another testament for Africa’s growing genomics capacity
The 16th Ebola Virus Disease Outbreak in Bulape Health Zone, Kasai, DRC. We were able to generate an accurate consensus genome in less than one hour starting from the library preparation. The newly EBOV genome is 99.97% complete and consists of 18,819 nucleotides.

8/ AI presents a leapfrogging opportunity to address workforce shortages, data infrastructure gaps, and fragmented systems. However, its implementation requires substantial investment in local tools, data systems, governance, and training.

7/ Algorithmic bias is a real concern. 65% worry about bias in AI models trained on non-African data. With <1% of global human genomes from Africa, this underrepresentation risks inequitable outcomes.

6/ AI is trusted—but not yet fully used. Most respondents see AI’s value in: ✅ Data analysis (84%) ✅ Early disease detection (82%) ✅ Diagnostic accuracy (80%) But fewer see it helping with admin tasks like reporting or resource allocation. This may need further investigation

5/ Barriers to AI adoption in genomics labs are systemic and multifaceted. 78% of labs lack training programs, 60% face high costs, 70% encounter infrastructure gaps, and 60% deal with regulatory inconsistencies. These challenges collectively hinder the widespread adoption of AI

4/ Training is the missing link. 🔹 90% want AI training 🔹 Only 6% have received any 🔹 Just 0.8% completed formal AI courses 🔹 Top interests: data analysis, predictive modeling, machine learning, ethics

3/ AI could be a game-changer by filling critical analytic gaps. AI enables rapid data analysis, outbreak forecasting, and real-time pathogen tracking. Yet only 4% of surveyed experts are highly familiar with AI in genomics. The potential is huge—but the skills gap is wider.

2/Genomics capacity is growing rapidly. In 2019, only seven countries had genomics labs, but by 2025, that number has increased to 46. Africa has seen an expansion of local genomics labs, which has helped detect new variants like clade Ib mpox.

Connectivity is critical to unlock the potential of genomics in Africa. #AfricaPGI’s pilot project, supported by the @gatesfoundation, has already demonstrated the impact of connecting genome sequencing labs with @Starlink satellite internet in Africa. Let’s scale this impact!
The National Tuberculosis Reference Laboratory (NTRL) in Eswatini has transformed its public health response through the deployment of Starlink high-speed internet. This upgrade has reduced genome sequencing turnaround times from several weeks to under seven days, enhancing both
