摘要: The COVID-19 pandemic caused many governments to impose policies restricting social interactions. A controlled and persistent release of lockdown measures covers potential strategies is subject extensive scenario analyses. Here, we use an individual-based model (STRIDE) simulate interactions between 11 million inhabitants Belgium at different levels including extended household settings, i.e., "household bubbles". burden impacted by both the intensity frequency physical contacts, therefore, bubbles have reduce hospital admissions 90%. In addition, find that it crucial complete contact tracing 4 days after symptom onset. Assumptions on susceptibility children affect impact school reopening, though business leisure-related mixing patterns more associated disease burden. An optimal deployment mitigation under study require timely compliance distancing, testing self-isolation.
