GOTHAM lab @gotham-lab.bsky.social · 23/09/20264/4 Control strategies do not remain equivalent once the virus evolves. Their relative effectiveness can be reversed. Reducing transmission slows both epidemic spreading and infectivity evolution. Shortening the infectious period suppresses transmission, but does not affect infectivity evolution. 010
GOTHAM lab @gotham-lab.bsky.social · 23/09/20263/4 This has striking consequences for epidemic control. Without evolution, longer interventions monotonically reduce the epidemic peak. But with evolution, the dependence becomes non-monotonic. Lifting control too early can therefore lead to a larger epidemic peak than doing nothing at all. 110
GOTHAM lab @gotham-lab.bsky.social · 23/09/20262/4 Allowing infectivity to evolve yields superexponential early epidemic growth. Then, the epidemic transition becomes abrupt, while the epidemic peak shows a non-monotonic dependence on the initial basic reproduction number: mildly infectious viruses can ultimately produce larger outbreaks. 110

GOTHAM lab @gotham-lab.bsky.social · 10/01/20265/6 But the microscopic organization is also important. Hyperedge overlap promotes polarization, as it reduces exposure to different opinions and reinforces local consensus 🤝 110
GOTHAM lab @gotham-lab.bsky.social · 10/01/20264/6 This effect is structural. As higher-order interactions become denser, agents increasingly participate in heterogeneous groups, which suppress polarization and promote moderation. We also show this analytically! 110
GOTHAM lab @gotham-lab.bsky.social · 10/01/20263/6 The key result is that sparse higher-order interactions promote polarization. When group interactions are sparse, agents are often embedded in homogeneous groups, limiting exposure to dissent and reinforcing extreme views. 110
GOTHAM lab @gotham-lab.bsky.social · 10/01/20262/6 Most opinion-dynamics models rely on pairwise interactions 👭+👬+👫+.... However, opinion formation often happens in groups: 👥👥👥👥👥👥+👥👥👥👥👥👥+👥👥👥👥+... where discussions can reinforce or moderate views. This demands a higher-order framework to explicitly capture group interactions and homophily. 110
GOTHAM lab @gotham-lab.bsky.social · 10/01/20261/6 And another article out in @commsphys.nature.com Sparse group interactions polarize…but dense group interactions moderate!! Polarization emerges as a structural effect of how groups are organized: www.nature.com/articles/s42... 164

GOTHAM lab @gotham-lab.bsky.social · 08/01/20266/7 Strikingly, the model partially reconstructs empirical epidemic trajectories, recovering the temporal ordering of strain emergence observed in genomic surveillance. Overall, epidemic dynamics 📈 depend crucially on the topology of genotype networks, beyond low-dimensional antigenic descriptions. 140
GOTHAM lab @gotham-lab.bsky.social · 08/01/20265/7 We then apply the model to Influenza A (H3N2). Its modular genotype network naturally produces: ☑️ lineage turnover ☑️ competition between multiple strains 120
GOTHAM lab @gotham-lab.bsky.social · 08/01/20264/7 The key result is that network topology alone controls the endemic behavior: ▶️ Homogeneous networks → stable equilibria. ▶️ Modular networks with mutant swarms → recurrent oscillations. No seasonal forcing is required to produce these oscillations!!! 130
GOTHAM lab @gotham-lab.bsky.social · 08/01/20263/7 To study this, we introduce an eco-evolutionary epidemic model coupling: ✔ Contagion ✔ Immune memory & cross-immunity ✔ Mutation as diffusion on genotype networks All within a minimal, analytically tractable framework. 120
GOTHAM lab @gotham-lab.bsky.social · 08/01/20262/7 Classical eco-evolutionary models describe antigenic drift in low-dimensional antigenic spaces. However, genomic data tell a different story: real viruses evolve on heterogeneous, modular genotype networks, with mutant swarms capturing different viral lineages. 130
GOTHAM lab @gotham-lab.bsky.social · 08/01/20261/7 🚨 New article out in @commsphys.nature.com We show that viral 🦠 evolution is best captured through complex genotype networks, whose topology alone can drive oscillatory endemic dynamics and epidemic variability: www.nature.com/articles/s42... 1106
