Effectiveness of Isolation, Testing, Contact Tracing, and Physical Distancing on Reducing Transmission of SARS-CoV-2 in Different Settings
Category: Article Summary
Topic: Modeling and Prediction
- A mathematical model that stratified individual-level transmission by setting (household, work, school, or other) and used BBC pandemic data from over 40,000 UK participants found that a high proportion of cases would need to self-isolate and a high proportion of their contacts would need to be traced to halt the epidemic, in the absence of other measures. These measures would be more likely to achieve control if combined with moderate physical distancing.
