Abstract
Methods: We present a sophisticated extension of a classical SEIR model. The simulation tool CovidSIM Version 1.0 is an openly accessible web interface to interactively conduct simulations of this model. The simulation tool is used to assess the effects of various interventions, assuming parameters that reflect the situation in Austria as an example. Findings: Strict contact-reduction including isolation of infected persons in quarantine wards and at home can substantially delay the peak of the pandemic. Home isolation of infected individuals effectively reduces the height of the peak. Contract reduction by social distancing, e.g., by curfews, sanitary behavior, etc. are also effective in delaying the pandemic peak. Interpretation: Contact-reduction mechanisms are efficient to delay the peak of the pandemic. They might also be effectively decreasing the peak number of infections depending on seasonal fluctuations in the transmissibility of the disease.
