A SARS-CoV-2 lineage once thought extinct has re-emerged after more than two years revealing how the virus can evolve undetected and return with significant genetic change.

Collaboration and continuous learning are at the heart of advancing genomics in Africa and the return of Dr Armando Djiyou to KRISP reflects just that.

A fellowship designed to close Africas health innovation gap is already reshaping how young scientists think and act beyond the lab.

Engaged research is reshaping how global health challenges are understood and addressed by bringing communities into every stage of the process. At CERI, this approach is helping to build more grounded, context-driven solutions for climate and infectious disease risks in vulnerable settings.


Two new publications by Prof Jo-Ann Passmore reveal a critical gap between scientific knowledge and womens lived realities where silence, stigma and power dynamics limit the impact of even the best research. By calling for ethical, community-driven design, the work points to a future where science is not only rigorous, but truly usable in womens everyday lives.

A new cohort of African fellows is turning epidemiological data into practical decisions from vaccination strategy to outbreak risk working directly with policymakers in their own countries. At a time of uncertain funding and rising pressure on health systems, the SACEMA Policy Modelling Fellowship shows how locally driven, data-led insight can protect and strengthen public health across the continent.
