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.

The COVID-19 house fire and the unbearable silence of fire alarms

WHO? The Emergency Committee

The international health regulations (IHR) provide for the Emergency Committee of the World Health Organization (WHO) to declare a Public Health Emergency of International Concern (PHEIC) in appropriate circumstances.

PHEIC is meant to be a signal to all countries that significant actions, aid and cooperation may all be needed. Critics have lambasted the late timing of PHEIC declaration for COVID-19 and also the opaque nature of the acronym.

The long-term health burden of COVID-19: further justification for NZ’s elimination strategy

This blog briefly surveys the emerging scientific evidence on the longer-term burden of symptoms and disease in survivors of the COVID-19 pandemic. Many of these symptoms point to damage in the brain and heart. These long-term harms add to the wide range of other reasons for Aotearoa/New Zealand to persist with its successful COVID-19 elimination strategy.

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.

In this blog, we introduce our modelling approach to estimating the transmissibility of the SARS-CoV-2 virus, the cause of the COVID-19 pandemic. We demonstrate the usefulness of the Wallinga model for the calculation of the effective reproduction number and show the major impact of the lockdown on containing the pandemic in New Zealand.
