Thanks. Very interesting. As a clinician in, so far, lucky New Zealand, I was interested in how increasing number of degrees of association in networks might affect transmission. I'm watching how Denmark reopening schools will, to my mind, likely create a very large network of associations very quickly.
Also found this paper, which appears to introduce heterogeneity of transmission as a concept. I suspect this is tautologous to how one might model death likelihoods in differing age/risk groups.
Maths so far a bit beyond my weekend explorer level, but the concepts seem useful.
