Table 6 Contagiousness

From: The influenza pandemic preparedness planning tool InfluSim

Basic reproduction number R 0 = 2.5
Relative contagiousness during the early infectious phase b L = 50%
Relative contagiousness of asymptomatic cases b A = 50%
Relative contagiousness of moderately sick cases b M = 100%
Relative contagiousness of very sick cases b V = 100%
Concentration of the cumulative contagiousness during the first half of the symptomatic period x 50 = 90%
  1. Sources: Contagiousness of asymptomatic cases: [11]; degree of contagiousness during the early infectious period and equality of the contagiousness of moderately and severely sick cases: assumed.
