Code for modelling combined isolation, tracing and physical distancing measures.

Note: this is working repository, so non-archived code and data are likely to change over time

Quick start guide

First, set local path in R to GitHub directory, e.g.: setwd("~/Documents/GitHub/2020-cov-tracing/") Data loading and main model run script are in scripts/contact_model.r. This calls the following R file:

R/model_functions.R - Function to sample individual contact networks, calculate secondary infections and effect of control measures.
