An Analytically Tractable Framework for Multi-Strain Epidemics: Resolving Algebraic Complexity to Map Oscillatory Dynamics
Nir Gavish
Multi-strain epidemiological systems frequently exhibit self-sustained oscillations, yet severe algebraic complexity has long obstructed a complete analytical characterization of t…
Modeling the Impact of Immune Boosting on Population-Level Vaccine Effectiveness
Nir Gavish, Guy Katriel, Zohar Rom-Ramon
We extend the standard susceptible-infected-recovered framework to incorporate natural immune boosting during a short-scale outbreak. By deriving closed-form final size relations,…
A new oscillatory regime in two-strain epidemic models with partial cross-immunity
Nir Gavish
Infectious diseases often involve multiple strains that interact through the immune response generated after an infection. This study investigates the conditions under which a two-…
Revisiting the exclusion principle in epidemiology at its ultimate limit
Nir Gavish
The competitive exclusion principle in epidemiology implies that when competing strains of a pathogen provide complete protection for each other, the strain with the largest reprod…
Dynamics of a two-strain epidemic model with waning immunity -- a perturbative approach
Nir Gavish, Musa Rabiu
Many infectious diseases are comprised of multiple strains with examples including Influenza, tuberculosis, and Dengue virus. The time evolution of such systems is linked to a comp…
