Sumary of Key to controlling COVID-19 is early intervention:

  • New Zealand has experienced one of the lowest mortality rates among all countries during the coronavirus disease 2019 (COVID-19) pandemic.
  • To date, the country has reported 10,790 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and 41 deaths in total.
  • Study design A study published in the journal Royal Society Open Science demonstrates the critical role of timely intervention in New Zealand’s success story.
  • The researchers used a stochastic branching process model to simulate the trajectory of COVID-19 transmission and control during New Zealand’s 2020 outbreak.
  • Study: Early intervention is the key to success in COVID-19 control.
  • Image Credit: mustafaclk / Shutterstock Three classes of interventions chosen for the study were as follows: (i) self-isolation/home quarantine, (ii) government-managed isolation (MIQ) and quarantine, (iii) population-wide control.
  • Due to restrictions under each of the four ALs, the population-wide control intervention simulated a reduction in transmission rate by a factor C (t) at time t.
  • While the relative transmission rate C (t) was equal to one in the absence of population-wide control, it had smaller values at higher ALs.
