Download Contact Surveys for Use in Infectious Disease Modelling // Download, cache, and manage social contact survey data from the social contact data community on Zenodo (https://zenodo.org/communities/social_contact_data) for use in infectious disease modelling. Provides functions to list available surveys, download survey files with automatic caching, and retrieve citations. Contact survey data describe who contacts whom in a population and are used to parameterise age-structured transmission models, for example via the 'socialmixr' package. The surveys available include those from the POLYMOD study (Mossong et al. (2008) doi:10.1371/journal.pmed.0050074) and other social contact data shared on Zenodo.
