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.

- 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.
