Interactive explainers
A collection of short, interactive, explainers on how malaria transmission behaves and how control interventions reshape it. Each one pairs a plain-language walkthrough with a toy model you can play with.
Work in progress — pages may changeWhy a modest change in mosquito survival or bed-net coverage can produce a much larger (or surprisingly small) change in prevalence and clinical cases. Trace a bed-net effect through the EIR → prevalence → incidence cascade.
Open explainer →When transmission-reducing control is withdrawn, naturally-acquired immunity has waned underneath it, so total protection can fall below where it started. Explore the three drivers of rebound with a toy protection-over-time model.
Open explainer →Where transmission is seasonal, malaria arrives in a short window and preventive treatment protects for only a short time. Explore how the impact of seasonal malaria chemoprevention depends on when its rounds land and on who they reach, with a toy model of cases through the year.
Open explainer →Malaria is a disease of young children only where transmission is intense. See how rising transmission concentrates clinical cases in the very young, through acquired immunity, with a live implementation of the Griffin model.
Open explainer →These explainers are my take on the Feynman technique: you only really understand a topic once you can explain it in plain language and build a working toy model of it. Each one works through an idea in malaria transmission and control that way.
