Weekly deaths declined in NZ’s lockdown – but we still don’t know exactly why

The pandemic-related lockdown is possibly the most dramatic public health intervention in NZ history. It helped achieve the elimination of community transmission of the COVID-19 virus in NZ. But it was also associated with 548 fewer total deaths than for the same period in 2019. Death rates (per 100,000 population) were also lower in 2020 than the three preceding years. There are a range of plausible reasons for this reduction (eg, fewer road crashes, fewer circulating respiratory infections) but we still need precise cause of death data (available in the future) to make more informed assessments.

Eliminate the pandemic virus causing COVID-19 or risk an animal reservoir

Prof John Potter*

Elimination has been an effective strategy for New Zealand in the management of the COVID-19 pandemic virus (SARS-CoV-2). Most other countries have not pursued this goal and are ignoring the opportunity even now. SARS-CoV-2 is not manageable by the influenza playbook; its longer incubation period makes tracing and isolation more practicable and puts elimination within reach. There is one additional argument in favour of elimination: the longer the highly infectious SARS-CoV-2 virus circulates in the human population, the greater is the likelihood that it will find a host among other animal species and that these will become a reservoir capable of transmission back to humans.

Pandemic terminology: getting it right matters for effective risk communication and management

Compared with other OECD countries NZ is a stand-out success story by ending community transmission of COVID-19. While there have been some well-publicised recent deficiencies (eg, quarantine organisation), there has still been no evidence of community transmission for many weeks. Nevertheless, further improvements in NZ’s response are possible and in this blog we detail how pandemic terminology could be upgraded. Consistent, accurate terminology could assist effective communication between political leaders, officials, scientists, international collaborators and the NZ public on key COVID-19 risk management issues.
