Why a “mouth and nose” lockdown with masks might help avoid a “full body” lockdown at home

The concepts of an Alert Level system, household “bubbles”, and social event size limits are all valuable pandemic control measures. Nevertheless, better “source control” of COVID-19 at various Alert Levels by requiring masks in public indoor spaces could reduce the risk of outbreaks (should there be border control failures) and reduce the likelihood that we would need to move back to tighter restrictions and lockdowns with the associated adverse economic, social and mental health effects.

The Strong Case for Mask Requirements in Public Transportation and Border Control Settings in NZ’s Current COVID-19 Pandemic Context

In this blog we identify six likely benefits from requiring fabric mask use in public transportation and border control settings in the “peri-elimination” context that New Zealand is currently in. Given these likely benefits and the relatively low costs (especially if the Government provides free masks as per Hong Kong), such a policy should be given very serious consideration by health authorities in the transition to level 2.

The need for a robust scientific definition for the elimination of COVID-19 from New Zealand

New Zealand is making good progress towards its elimination goal for COVID-19 at the country-level. In this blog we present the case for a scientific definition of elimination to help guide our national COVID-19 response. The definition must be objectively verifiable, with appropriate levels of testing and surveillance systems in place. It should ideally be refined in collaboration with Australian health authorities, as part of a strategy of opening up our shared borders for easier travel between the two countries.

What we would like to see on the Ministry of Health’s website to better inform progress on COVID-19 elimination

In this blog we analyse data from the Ministry of Health’s COVID-19 website and display a key graph that we think should be routinely on that website. We also detail a potentially more useful way to categorise case data so that the public and research community can better track progress on the path to COVID-19 elimination. Both the graphical and tabular presentation of case data need to emphasise the critical distinction between imported cases (who should be safely isolated in supervised quarantine facilities) and transmission within NZ that would threaten elimination status.

Why NZ should consider adopting “mass masking” as an additional step to speed elimination of the Covid-19 pandemic

Widespread public mask use is common in some Asian countries as a control measure in the current Covid-19 pandemic. There is some suggestive laboratory and epidemiological evidence of benefit for such mask use. Since the costs of mass masking are relatively low and there are no apparent substantial down-sides, it should be given serious consideration by the NZ Government to speed progress towards the elimination goal.
