Malaria kills over 1 million people every year. Previous attempts to control malaria have failed and for the past 40 years global eradication was thought to be impossible. However, there are now new, more effective, tools available such as insecticide treated bednets and more powerful antimalarial drugs. There is also unprecedented commitment from international bodies such as the WHO and the Roll Back Malaria Partnership. As a result, global malaria eradication is very much back on the international agenda. The difficulty is knowing which intervention strategies to use and how best to combine them to achieve maximum impact in a variety of different settings. Mathematical modelling has great potential as a tool to help guide and inform these decisions by predicting the impact of various strategies before funds are committed. Although many models of malaria exist, very little modelling of malaria elimination has thus far been attempted.
A user-friendly web-based mathematical model is being developed to examine the elimination potential of all the current major malaria control interventions, alone and in combination, in a variety of settings. The first version of this model can now be accessed via the link at the bottom of this page. It is a deterministic population dynamic model and is coded in Microsoft Silverlight. The model structure is based on a previously published framework which can be accessed in the publication The role of simple mathematical models in malaria elimination strategy design. Users can enter their own data and run the model themselves over the internet. This model will be refined and developed in collaboration with users with the ultimate aim of developing it into a tool to help plan local elimination strategies. Users can make suggestions and help develop refinements and additions via the online forum or by email. We will share the model code on request so specialists, programmers and other modellers can review it and see how it is constructed. Our team will work in collaboration with these users to continuously update and refine the model to maximise its potential and to assist non-mathematicians with the interpretation of the model results.
We have produced a free, internet-based, user-friendly and interactive mathematical model of malaria elimination as a tool for policy makers. We will develop and refine this model in collaboration with users to maximise its potential as an educational and public health policy planning tool. This will enable optimisation of local malaria elimination strategies before commitment of valuable resources.

The Malaria Elimination website is made up of:
- A mathematical model fully decribed in this publication is made available under the terms of the Creative Commons Attribution Non-commercial License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited; and
- The modelling code, which is in Berkeley Madonna format. This is available on request via a forum so that specialists, programmers and other modellers can download it, see how it is constructed and make suggestions for its development. The modelling code is not generally available during this prototype phase, other than on request through the forum.
Users should carefully note the following:
- The model is intended to allow policy makers and public health specialists to enter their own data specific to their location and run the model themselves using it as a tool to explore the possible relative impact of different local elimination strategies
- By definition, this simple model does not include every available consideration relating to malaria prevention: the model requires very little data input and can be run quickly for a range of scenarios to understand the more general behaviour of malaria transmission
- It is therefore suitable to be used as a first step by policy makers and only for investigation of the relative effects of different elimination strategies in the short- to medium-term: note that, for longer term planning, more complex and detailed models will be required
