Pathogen.jl is a Julia software package for individual level models of infectious diseases (Deardon et al, 2010). It's capabilities include stochastic simulation and Bayesian inference of SEIR, SEI, SIR, and SI individual level models, with fully customizable functions describing individual specific transition rates between disease states (i.e. form of, and relevant risk factors to, susceptibility, transmissibility, latency, removal, and sparks functions). Pathogen.jl is written purely in Julia, which enables this generality without incurring performance costs.
Pathogen.jl infers transmission pathways (i.e. who-infected-who). This inference is completed using a Gibbs step in our specialized MCMC algorithm. This specialized MCMC algorithm also performs event time data augmentation. A detailed overview of this algorithm can be found here.
The current release can be installed from the Julia REPL with:
pkg> add PathogenThe development version (master branch) can be installed with:
pkg> add Pathogen#master
Examples of Pathogen.jl workflow are included in the examples directory as a Jupyter notebooks.
- SIR simulation, inference, and visualization
- Analysis of a Tomato Spotted Wilt Virus experimental epidemic
- Analysis of 1861 Hagelloch Measles outbreak
This package is detailed in Pathogen.jl: Infectious Disease Transmission Network Modeling with Julia, in the Journal of Statistical Software.
