From static thresholds to dynamic waves: How biological memory destabilizes malaria transmission Potential

Steeven Belvinos Affognon, Priscille Barreaux, Shirley Abelman, Antoine M. G. Barreaux

This paper develops a delay-based framework to model malaria transmission dynamics, showing that biological memory from developmental delays can create time-dependent transmission potential and stability fluctuations.
