"The Kasai outbreak emphasises the case that genomic stasis might be a recurring feature of Ebola virus ecology. A lineage that is virtually unchanged since 1976 challenges assumptions about Ebola's evolution and exposes the blind spots of surveillance."

Synchronized dynamics of dengue across the Americas Dengue has strong synchrony across the Americas, indicating that a mix of intrinsic and extrinsic factors drives epidemic transmission dynamics.

A new epidemiological analysis parses #dengue transmission in the Americas on a continental scale, defining synchronized seasonal and multiannual patterns in outbreaks and the influence of climatic factors such as El Niño.

Pathways to an Intergovernmental Panel on Pandemics: lessons from the IPCC and IPBES Colin J Carlson, Christopher H Trisos, Ben Oppenheim, Shweta Bansal, Sara E Davies, Aïda Diongue-Niang, Victoria Y Fan, John D Kraemer, Rachel Golden Kroner, Lawrence O Gostin, David T S Hayman, Marion Koopmans, Torre E Lavelle, Carlos G das Neves, Zoe O’Donoghue, Laura M Pereira, Benjamin Roche, Matiangai Sirleaf, Kayla Zamanian, Carlos Zambrana-Torrelio, Alexandra L Phelan Pandemics pose a global threat to human wellbeing, justice, economies, and ecosystems and are comparable with other planetary crises such as climate change and biodiversity loss in terms of urgency and impact. The global community would benefit from a dedicated scientific synthesis body to assess pandemic risks and solutions. In this Personal View, we explore proposals for an Intergovernmental Panel on Pandemics and assess potential pathways to its creation. Learning lessons from the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) might help national governments and international organisations to chart a course through important decisions about format, governance, operations, scientific scope and process, and ability to recommend policies that make the world safer.

🚨 Very, very big news. Today, a global coalition - including members of the IPCC, IPBES, and WHO expert advisors, as well as independent virologists, epidemiologists, and lawyers - started the process of creating an "IPCC for Pandemics."
