The malaria model

An individual-based malaria model that added Plasmodium vivax, hypnozoites and all

epidemiologymalariasimulationr-packagereproducibility
◆Current state
malariasimulation is an individual-based malaria transmission model. The visible history is short but consequential: v2.0.2 extended the model beyond its original parasite species to Plasmodium vivax, and the most recent tag is not a code release at all but a coordinated snapshot freezing the whole malariaverse suite at a known state.
◆Where it's heading
The direction is toward being a multi-species platform rather than a single-parasite simulator, and toward being usable as a reproducible research artefact. The P. vivax work was not a wrapper over the existing model — it added hypnozoites, competing hazards, an equilibrium solution and species-specific immunity behaviour, while deliberately removing blood and severe immunity components that do not apply. The snapshot tag addresses the other half of that: analyses built on a fast-moving suite need a version set they can return to.
◆Prediction
The snapshot being tagged immediately before an announced update suggests the next release changes enough to break existing analyses, which is why the freeze was published first. The entries do not say what that update contains.

    malariaverse suite frozen at a reproducible snapshot tag

    Not a feature release but a coordinated snapshot: every package in the malariaverse suite carries the same `malariaverse_01_2025` tag, freezing the suite immediately before an upcoming update so existing analyses can be reproduced against this exact version set. It ships no behaviour change, but it gives users a pinnable install target for the whole suite.

    Plasmodium vivax model with hypnozoites and relapse dynamics

    ⚡ SPARK

    The release that makes malariasimulation a two-species model, adding Plasmodium vivax across roughly a dozen coordinated changes rather than as a variant of the existing parasite. It reshapes immunity, infectivity and drug handling specifically for P. vivax and supplies an equilibrium solution for the new model.
