Effectiveness of isolation and contact tracing for containment and slowing down a COVID-19 epidemic: a modelling study

Category:

Topic:

  • The analyses from this modeling study showed that transmissibility and the duration of the latent period relative to the duration of the incubation period have a strong impact on how well the disease can be controlled. 
  • While isolation and contact tracing will not fully control the COVID-19 outbreak, the authors emphasize that these are still important aspects of effective containment strategies as they will eventually reduce growth rates and increase epidemic doubling times.
