Successful control of the current Covid-19 outbreak in NZ is looking feasible but many challenges remain. Therefore to maximise the chances of returning to elimination status and improve our resilience to future outbreaks, we propose the following potential enhancements: (i) develop a robust system to allow for region-specific Alert Levels; (ii) mandate QR code scanning; (iii) expand mask use requirements to all essential workers; (iv) greatly prioritise vaccination of essential workers; and (v) consider the suspension or minimisation of all incoming international passenger flights during the outbreak.

Australia has generally succeeded in eliminating community transmission of the pandemic virus SARS-CoV-2, but the Greater Sydney region is currently facing a large COVID-19 outbreak, driven by the Delta variant. The New South Wales Government is struggling to control the outbreak and the grim situation holds a number of lessons for NZ.

Particular words and phrases can frame how issues are considered and the extent to which they imply the need for a corrective response to improve system design or delivery. After considering a range of words, we consider that the phrase “border system failure” comes closest to providing a clear, unambiguous description of situations where there are infectious cases in the community and corrective action is needed to protect public health. A typology for describing problems within NZ’s border control system could also include ways of classifying “border system hazards” that may represent “near misses” that should also stimulate corrective actions.

Despite a WHO-led investigation, compelling evidence on the origin of the SARS-CoV-2 virus remains inconclusive. The WHO investigation concluded in favour of a natural origin, being satisfied that ‘asking whatever questions we wanted’ and obtaining answers to these questions ruled out a laboratory leak. Researchers at the Wuhan Institute of Virology stated that they do not keep similar viruses to SARS-CoV-2, and they have appropriate safety training (while not divulging actual laboratory records).

In this blog we briefly consider a new Report from a European think tank that aims to identify an optimal COVID-19 response strategy. It considers mortality data, GDP impacts, and mobility data and suggests that COVID-19 elimination appears to be superior to mitigation/suppression strategies in health and economic terms. Nevertheless, more data and a longer-term perspective is needed, before we can be really certain about the relative benefits and costs of different COVID-19 control strategies.
