Topic:

  • This study suggests that early adoption of social distancing is more effective than delayed implementation, even of highly restrictive measures, implying that there may be a threshold of public health interventions after which a decline in death rates begins to occur. 
  • This method may be helpful in planning for and monitoring the relaxation of social distancing and evaluating the effectiveness of implementation in individual countries.
