The most important notations and concepts used in the article.
| Z | transmission tree |
| Γ(·) | proposal distribution for sampling transmission trees, i.e. Z ∼ Γ(·) |
| T | the genealogy of the considered isolates in a transmission cluster; here T is a matrix that describes the time to most recent common ancestor for all the pairs of considered isolates |
| TZ | a matrix describing for two different infectees the time of coalescence along the transmission tree |
| Λ(·) | proposal distribution for sampling the genealogy of the isolates (i.e. T ∼ Λ(·)) we use the posterior distribution of T as Λ(·) |
| SZ(k) | a set all the different sequences of k branches of tree Z, each extant during the follow-up |
| x | a particular combination of branches, i.e. x ∈ SZ(k) |
| Ψ(·) | posterior predictive distribution for the time span of infectiousness for a household; in our application this corresponds to the distribution for the branch lengths for transmission trees Z |
| r | the rate at which infectious households infect each other |
