Modelling studies analyzing preventive measures often assume that the intervention will be available for a large part or the whole population [6, 8, 16] . E.g. Carrat et al. analysed the effect of combined interventions targeting up to 70% of households in their ''small-world-like'' model [17] . In contrast, our model focuses on the initial stage and the first few thousand cases in Germany, and on the delay that can be achieved. We have restricted the analysis of maintaining the less intensive CCM2 strategy for 10,000 courses. The maximum amount of antivirals used in this approach corresponds to treatment courses for less than 0.1% of the German population and 5% of the amount available for seasonal influenza in the winter season. After the end of isolation, the treated contacts were assumed to remain susceptible to the infection. However, these conservative assumptions result only in a shift (depending on R0 significant) of the epidemic curve and virtually no reduction of the overall attack rate.
