From: Analysis of timeliness of infectious disease reporting in the Netherlands

  percentage notifications ≤ 1 Ic (%) percentage notifications ≤ 2 Ic (%) m
Measles
(Ic 7 days) n=134
48.5 60.4 71.6 73.9 0
HAV infection (Ic 14 days) n=1518 71.4 78.7 90.3 93.1 65
  1. Ic (interval corrected) = LP (latent period)-× (period of infectiousness in index patient preceding symptom onset)
  2. [ ]= total number of notifications
  3. m = number of missing i.e. excluded notifications
