In this episode, Specialty Primary Care Physician Dr Peter Lin takes GPs on a tour from ACE2 to cytokine storms, showing how a virus that doesn’t even move by itself can quietly dismantle multiple organ systems and what that means for your highest-risk patients this winter:  Why COVID-19 is more than a respiratory virus   How ACE2 disruption drives organ damage and clotting   The renin–angiotensin system and long COVID complications   Why COVID differs clinically from influenza and RSV   Identifying high-risk patients using viral load and cellular damage   Practical strategies for testing, vaccines and antivirals  Host: Dr David Lim | Total Time: 33 mins Expert: Dr Peter Lin, Specialty Primary Care Physician

Professor Adrian Esterman joins David to unpack the real state of COVID 19 in older Australians why the virus still hits them hardest, why so few are up to date with boosters, and how atypical presentations can derail timely antiviral treatment. This practical, GP focused discussion offers clear, actionable ideas for improving protection in both community and aged care settings ahead of winter. Understand why COVID-19 has become “quieter” overall, yet remains disproportionately deadly in older people, especially those who are frail or living with multiple comorbidities. The discussion unpacks how atypical presentations in older adults can delay diagnosis, closing the narrow five day window for antivirals. Practical steps for GPs working with aged care facilities, including the value of standing outbreak protocols, proactive consent processes, and streamlined access to antiviral therapy. Explores why COVID-19 vaccination and booster uptake in older Australians remains worryingly low, despite strong safety data and clear reductions in mortality. Consultation strategies to address vaccine fatigue and misinformation.   Host: Dr David Lim | Total Time: 42 mins Experts panel: Prof Adrian Esterman, Epidemiologist and Biostatistician
