The social lives of viruses | Asher Leeks | TEDxNewEngland
TEDx Talks· 2025-10-07 17:01
Core Argument - The traditional view of viruses as solitary particles is incomplete; viruses exist within communities and exhibit social behaviors [2][3] - Understanding viral sociality, including cooperation and cheating, is crucial for predicting and potentially manipulating viral behavior, especially in the context of pandemics [9][32] - Game theory and evolutionary biology provide tools to model and understand viral interactions, offering insights into viral evolution and potential antiviral strategies [18][19] Viral Sociality - Viruses form communities both as particles and within infected cells, engaging in social interactions at the molecular level [11][12] - Viral communities exhibit cooperation, where viruses work together to enhance reproduction, and cheating, where viruses exploit the resources of others without contributing [13][15] - The balance between cooperation and cheating in viral communities is a constant evolutionary tension, influencing viral dynamics and potentially leading to extinction or new forms of viral existence [17][27] Implications for Pandemic Response - Understanding the rules of viral sociality could lead to new antiviral strategies that target viral cooperation, potentially preventing or mitigating future pandemics [31][32] - The tragedy of the commons, where individual cheating undermines the collective good, applies to viral communities and can be exploited for antiviral interventions [23][31] - By manipulating viral social behavior, it may be possible to force viruses to give up their social lives, thereby controlling or eliminating infections [33] Viral Diversity and Evolution - Viruses are incredibly diverse and evolve in complex ways that are not fully understood, posing a significant challenge to pandemic preparedness [5][6] - Studying viral social interactions can provide new evolutionary explanations for puzzling viral phenomena, such as the split genomes observed in approximately 20% of plant viruses [28][29] - Conflict within viral communities can be a creative force, driving the evolution of new viral strategies and forms [30]
'Dangerous time' for public health not just in U.S. but around the globe, warns doctor

Public Health Threats & Challenges - Public health faces a dangerous time due to US pullback on programs like PEPAR and WHO involvement, threatening the public health structure [3] - The world is constantly in a battle with microbes, which still kill more people than wars [5] - Current vaccine production capacity is limited to vaccinating about 25% of the world's population within 12-15 months after an influenza pandemic begins [6] Vaccine Access & Policy - There is confusion regarding vaccine access, particularly for children, with concerns that guidelines could create barriers to vaccination [8][9][10] - Concerns exist that some statements may discourage vaccine use, even though over 160 children in the US died from COVID in the past year, many without known risk factors [9] - Claims that there is only one study on childhood vaccines are false; 511 such studies have been published [11] Future Pandemic Preparedness - The degradation of public health services coincides with the potential for even more serious pandemics than COVID-19 [4] - mRNA technology is crucial for rapidly producing vaccines, potentially enough to vaccinate the entire world in the first year of a pandemic [6][7]

Economic Impact - Pandemics have political and economic effects [1] - Covid-19 had far-reaching and unexpected consequences [1]

Pandemics do not just sicken and kill. They have political and economic effects, too. Two recent books examine the far-reaching and unexpected consequences of covid-19 https://t.co/JvuCPQsOgP ...

Research & Development - The world is missing out on research benefits amid biodiversity pressure and pandemic threats [1] - Biology now possesses tools for significant advancements [1] Policy & Regulation - The Nagoya Protocol is identified as a potential factor hindering research progress [1]

The world at large is forgoing the benefits of research when biodiversity is under huge pressure, the threat of pandemics looms large and biology at last has the tools to make important progress. One reason is the Nagoya protocol https://t.co/wIenJAN5nk ...
