The parasitic roundworm, Ascaris lumbricoides infects humans when eggs excreted in faeces are ingested. The eggs pass through the body and develop into mature worms in the intestine. It is estimated that up to a quarter of the world's population is infected in areas where there is poor sanitation.

Model code

We are committed to making our model code available for use by other modellers. Below are links to code used in a recent publication:

Coffeng, Truscott et al. Comparison and validation of two mathematical models for the impact of mass drug administration on Ascaris lumbricoides and hookworm infection. Epidemics 2017. The code for the Imperial College model is available here. The code for the Erasmus MC model was published with:

Coffeng et al. Feasibility of controlling hookworm infection through preventive chemotherapy: a simulation study using the individual-based WORMSIM modelling framework. Parasites and Vectors 2015.  The code is available under Additional Files.
