The Effect of Restrictive Interactions between Susceptible and Infected Individuals...
summary
Rigorous analysis introduces a contact process with avoidance with infection rate λ and avoidance/deactivation rate α, using Harris-style graphical constructions, block constructions, and eigenvalues of a leaf-generator. On Z and cycles the phase boundary shifts roughly linearly in α (same qualitative super/subcritical regimes), while hubs drop from exponential to polynomial instead of exponential survival with exponent δ = 1/γ given by a generator eigenvalue. A separate pool-testing badging framework (green/orange/red badges, ODEs and agent-based sims) shows non‑monotone costs and sometimes optimal pool sizes >1.
