  • Undetectable, Then Detectable: Decoding the HIV “Viral Blip”

    Undetectable, Then Detectable: Decoding the HIV “Viral Blip”
    Jun 30 2026
    Why does an undetectable HIV viral load sometimes flip to “detectable” — and what does that actually mean for the patient? Host Ben Plumley talks with Ben LaBrot (Professor of Global Medicine, USC; Medical Affairs Lead, Roche Molecular Diagnostics) and Daniel Griffin, MD (Chief of Infectious Disease, Island Infectious Disease Medical, Instructor of Clinical Medicine, Columbia University, Host, This Week in Virology) about the “viral blip” — a brief, low-level detectable result that occurs even in patients on fully effective antiretroviral therapy. The conversation covers the science behind ultra-sensitive viral load assays, the real meaning of U=U (undetectable = untransmittable), why lab handling and patient illness can cause a temporary blip, and why so many patients are blindsided by results in their MyChart before their doctor has a chance to explain. Ben and Daniel also discuss “prebunking” — preparing patients in advance — and the underused role of community health workers in HIV education. Topics: HIV, viral load, U=U, undetectable, antiretroviral therapy, infectious disease, diagnostics, patient communication, global health. 00:00 Welcome and Setup 00:13 The Viral Blip Riddle 01:20 Meet the Guests 04:02 Why Blips Matter Now 05:54 Assay Sensitivity and LOD 06:22 What Undetectable Means 08:36 U Equals U Confusion 12:50 MyChart Panic and Context 17:09 Prebunking Patient Fear 18:21 Why Blips Happen 20:59 Tech Problem Analog Fix 22:26 Testing Noise Sources 23:28 RNA Fragments Explained 25:16 Sample Handling Pitfalls 26:46 Reporting Low Copy Results 29:02 Managing Patient Anxiety 33:14 When a Blip Matters 36:12 Changing the Landscape 40:48 Community Outreach Ideas 43:12 Key Takeaways Check Out Ben’s Substack: https://substack.com/@benplumley1 Join the Conversation!

  • AIDS 2060 Ep 02 - African-Led Research for an African Epidemic

    AIDS 2060 Ep 02 - African-Led Research for an African Epidemic
    Jun 26 2026
    In this second episode of AIDS2060, Ben sits down with Dr Andrew Kambugu, Executive Director of the Infectious Disease Institute at Makere University in Kampala Uganda. They discuss the state of the clinical response to HIV in Africa, and Andrew sets out a research and implementation agenda that gives equal weight to HIV prevention, treatment and diagnosis. He compares it to floor cleaning: you have to switch the water off at its source and not rely exclusively on mopping water up on the floor. In other words, African solutions for African problems of an epidemic that we know how to treat but can’t control rates of infection across the continent. 00:00 AIDS 2060 episode 2 intro 02:20 Three pillar overview 02:58 Prevention breakthroughs 04:19 Treatment momentum risks 06:00 Injectables and dual therapy 08:24 Integrating chronic care 10:12 Circumcision and ownership 14:07 Rethinking optimization 20:03 Africa led R & D 26:02 Africa CDC and AMA 27:42 Building Regulatory Capacity 28:21 Private Sector Momentum 29:37 Uganda Manufacturing Model 31:55 Academia Industry R&D 33:35 Africa Research Priorities 36:44 Biotech and Diagnostics 44:55 Funding and Innovation 49:51 Closing Thanks and Outro Check Out Ben’s Substack: https://substack.com/@benplumley1 Join the Conversation!

  • Redefining Global Health in the 21st Century, Chapter 1: The End of the Old Order – and What Comes Next

    Redefining Global Health in the 21st Century, Chapter 1: The End of the Old Order – and What Comes Next
    Jun 23 2026
    A Shot in the Arm Media in partnership with UCSF Institute for Global Health launched a nine-part series to explore the future of global health built around the book Redefining Global Health in the 21st Century, co-authored by Dr. mike Reid (UCSF Institute for Global Health Sciences) and Ambassador Eric Goosby (former U.S. Global AIDS Coordinator and former PEPFAR Chief Medical Officer). In this episode, what if the greatest threat to global health isn't a new virus — it's us? Our funding fatigue, our outdated playbook, our addiction to replication over adaptation. We've saved millions of lives. But are we sleepwalking inexorably into decline, into the enshittocene. Eric and mike don’t think so. And they’ve written a book, “Redefining Global Health in the 21st Century, that sets out an alternative, optimistic future. In this episode, they reflect on the end of the old order, and the implications for innovation and scale up into a new era in global health. mike and Eric are hosted by Ben Plumley from A Shot In The Arm Media. 00:00 Series Kickoff Recap 01:25 Early Wins Foundations 02:07 Global Fund and PEPFAR Tensions 04:40 What Worked Best 06:29 Malawi Dependency Shock 08:48 Why Systems Collapsed 12:50 Donor Ecosystem Incentives 18:30 Designing Better Partnerships 23:25 New Players Multipolar Era 27:21 Philanthropy Promise and Peril 31:44 Limits of Philanthropy 32:24 Gates Foundation Lessons 33:41 Sustainability Commitments 35:56 Country Led Coordination 37:45 Innovation Beyond Tech Fixes 39:28 Private Sector as Resource Motor 42:02 Equity Risks and Guardrails 44:24 Indigenous Knowledge in Trials 48:08 From Pilots to Scale 52:19 Access and Global Rollout Rules 54:34 Paradigm Shift Takeaways 55:25 Episode Wrap and Next Steps Learn more about the book: https://bit.ly/redefining-global-health More from UCSF Institute for Global Health Sciences: https://globalhealthsciences.ucsf.edu Check Out mike Reid’s Substack: https://substack.com/@reimaginingglobalhealth Check Out Ben’s Substack: https://substack.com/@benplumley1 Join the Conversation!
