During the COVID-19 pandemic in the Netherlands, transmission pairs were collected by asking reported cases whether they could identify their infector, yielding 678,482 pairs in total. This repository contains a collection of aggregated data sets of these transmission pairs:

summary_infectees: number of infectees in transmission pairs stratified by age group, sex, week, residential province

serial_interval: number of transmission pairs stratified by serial interval, ranging from -10 to +30 days; serial intervals outside this range have the value -11 or +31 days

summary_serial_interval_variant: summary statistics (mean, sd and fraction negative) of serial interval for periods dominated by different SARS-CoV-2 variants

transmission_matrix_settings: number of transmission pairs* stratified by infector age group, infectee age group and transmission setting

transmission_matrix_vaccination: number of transmission pairs* stratified by infector age group, infectee age group, infector vaccination status and infectee vaccination status for September 2021

* groups containing less than 5 transmission pairs are omitted
