Agent-Based Simulation for Evaluation of Contact-Tracing Policies Against the Spread of SARS-CoV-2

Topic:

  • Bicher et al. developed an agent-base model of SARS-CoV-2 transmission in Austria that incorporates information about the disease course, contact networks(households, workplaces, schools), and infection control policies (lock down, contact tracing). The authors found that individual contact tracing (compared to household-level or workplace-level contact tracing) was the most effective policy, and could result in an81% reduction in incident cases while quarantining only 28% of the population.
