Can we track how the virus is spreading in the Ebola outbreak in DR Congo? Claude Science is providing bioinformatics support to scientists at @inrb_kinshasa responding to one of the most pressing global health challenges right now: virological.org/t/reproducti… Drs. Placide Mbala Kingebeni, Tony Wawina Bokalanga, Collins K. Tanui, Emmanuel Lokilo, Princesse Paku, their team, and I used Claude Science to analyze >800 virus genomes and infer the most likely ‘virus family tree’ to reveal when the outbreak started, how and where the virus is spreading, and whether spread is increasing or slowing. Claude Science enables researchers to run complex bioinformatics workflows, including Bayesian phylodynamic inference, and go from sequences to public health insights in minutes (or hours for BEAST X analyses). It also allowed us to compare how stable the results are across >20 different phylodynamic workflows and data subsets, and easily rerun analyses as new data comes in: our current report shows results for genomes released up to last Saturday. Our results are further corroborated by this preprint, posted one day after the initial Claude Science results, which independently estimated the viral effective population size for genomes collected through mid-August and finds the same early growth rate and slowdown since June: medrxiv.org/content/10.64898…

How do you build Africa’s largest hydroelectric power plant? The Grand Ethiopian Renaissance Dam took more than a decade to build, with Ethiopians contributing to its financing through bonds, salaries and public fundraising. Read in The Republic:

Congratulations to Prof. Jean-Jacques Muyembe-Tamfum (@MTamfum) and Prof. Peter Piot on the #VirchowPrize2026! A well-deserved honour for both, and for everyone inspired by their work. #INRB
It is a privilege to deliver the laudation for Prof @Mtamfum and Prof Peter Piot at #VirchowPrize2026 Few have given more to advance public health while mentoring generations of future leaders We celebrate not only their scientific achievements but also their deep humanity

#Malaria “Elimination is fundamentally about equity, reaching those who are consistent” @LekeRose
Eliminating malaria is fundamentally about equity because the disease persists where systems are weakest- remote, underserved, & cross-border communities. Read more on my co-authored op-ed with Dr. Seynudé Jean Fortune Dagnon on the shift to elimination. africahealthwatch.com/p/from…

Today, I am proud to launch the African Strategic Advisory Group on Genomics (ASAG) — an African-led advisory body to guide how the continent governs, generates and uses genomic data to protect our people. ASAG will strengthen disease surveillance, enhance epidemic preparedness, support ethical data governance and accelerate the development of African-led medical countermeasures — placing Africa at the centre of the global health security agenda. This is genomics on Africa’s terms: coordinated, ethical and grounded in our priorities. ----- Aujourd’hui, je suis fier d’annoncer le lancement du Groupe consultatif stratégique africain sur la génomique (ASAG) — un organe consultatif dirigé par l’Afrique, chargé d’orienter la manière dont le continent gouverne, produit et utilise les données génomiques pour protéger nos populations. L’ASAG contribuera à renforcer la surveillance des maladies, améliorer la préparation aux épidémies, soutenir une gouvernance éthique des données et accélérer le développement de contre-mesures médicales dirigées par l’Afrique — plaçant le continent au cœur de l’agenda mondial de la sécurité sanitaire. Il s’agit d’une génomique définie selon les priorités de l’Afrique : coordonnée, éthique et ancrée dans nos réalités. Read more: ow.ly/Fiu250YUta4

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.
