In Netherlands COVID-19 surveillance (27 Feb 2020–11 Apr 2022), 8.5% of 8,003,008 reported cases (678,482) were linked to a most probable infector.
- Why it matters: Routine case data capture who became infected but not who infected others, limiting direct estimates of transmission timing and mixing patterns.
- What they did: Investigators used routine reporting where infectees named their most probable infector, then evaluated representativeness, serial interval estimates, and vaccination and age-group mixing in linked transmission pairs.
- The result: Linked pairs produced a mean serial interval of 3.6 days (sd 3.4) and showed age-group transfers consistent with contact patterns, plus September 2021 transmissions mostly among not (fully) vaccinated people.
