February 28 marks three years since COVID was first reported in Aotearoa New Zealand. Since then there have been main advances in our understanding of this an infection and the instruments and methods to fight it.
Here we describe three huge alternatives to enhance our response as we enter the fourth yr of the pandemic.
Strategy is vital to driving down an infection
New Zealand’s response technique began with elimination, which minimised an infection and loss of life from COVID through the first two years of the pandemic.
It additionally allowed time to roll out vaccines and enhance therapies earlier than widespread an infection through the pandemic’s third yr. These measures decreased the case fatality danger from about one in 100 through the first two years to lower than one in a thousand now.
The internet impact was the bottom cumulative extra mortality within the OECD throughout this era.

The world is now transitioning from an emergency pandemic response to treating COVID as one other necessary infectious illness to be managed. The first huge problem is figuring out an optimum technique for managing an infection now that COVID is at all times current.
Elimination will not be presently possible with obtainable and acceptable interventions, so the choice is concerning the optimum degree of management from suppression to mitigation. This is a danger evaluation query based mostly on acute and long-term impacts of COVID infections.
To put together for future pandemics, we will study from the OECD’s high two performers: New Zealand and Iceland
In 2022, COVID turned the second main reason behind loss of life in New Zealand, behind ischaemic coronary heart illness. Globally, it’s prone to have been the third main reason behind loss of life for the previous three years (2020-22).
The immunity ensuing from the cumulative results of vaccination and prior publicity is decreasing the severity of an infection. Unfortunately, the proof from a number of strands of analysis is that COVID an infection is a multi-organ illness with signs generally persisting after three months as lengthy COVID.
Infection might harm the circulatory system, mind and lungs. It additionally will increase the danger of subsequent coronary heart assaults and different circulatory illnesses and seems to be driving a rise in extra mortality in lots of international locations.
COVID will not be influenza, the place symptomatic infections usually happen years aside. With COVID, reinfections are widespread, and every carries a danger of sickness, hospitalisation, loss of life and incapacity from lengthy COVID.
When does COVID change into lengthy COVID? And what’s taking place within the physique when signs persist? Here’s what we have learnt to date
The life-course results of experiencing a number of infections are usually not but recognized.
This proof helps a suppression technique to minimise the frequency of infections and reinfections. Major worldwide opinions describe this as a vaccines-plus strategy which makes use of a mixture of management measures in addition to vaccines.
New Zealand has partially adopted this strategy however might want to do extra and clearly articulate a suppression technique as a unifying aim for choosing interventions.
Effective and equitable supply is vital
It may be argued we must always deal with COVID extra like different infectious illnesses. The converse technique is that we must always deal with different infectious illnesses extra like COVID.
There is a convincing argument for an built-in strategy to respiratory infections that builds on the co-benefits of addressing a number of infections, together with a powerful emphasis on fairness.
In the previous we have now accepted the annual loss of life toll of round 500 from influenza and its huge impression on our hospital system. Yet influenza largely disappeared through the time of COVID, in New Zealand and another international locations, even these with much less stringent management measures. This discovering reveals that the burden of influenza will not be inevitable.
We have to establish the best and cost-effective mixture of respiratory protections. Examples embody focused and common vaccine programmes, improved air flow in public buildings and strategic masks use in enclosed public environments (for instance, public transport).
These interventions must be in contrast with different potential investments in well being to resolve one of the best use of accessible sources.
We know Māori and Pasifika have the best charges of hospitalisation and loss of life from COVID and decrease ranges of vaccination. This is a powerful argument for persevering with to strengthen Māori well being management as exemplified by the brand new Māori Health Authority Te Aka Whai Ora.
An built-in programme addressing respiratory infections could be strengthened by analysis and surveillance. It is necessary to know and deal with limitations to attaining excessive inhabitants protection of key interventions. We additionally want methods to fight disinformation to assist maintain the social license for public well being measures.
High-quality built-in surveillance of respiratory infections would provide information on epidemiology, genomics and well being fairness.
We should study and stop the following pandemic
Given the acute disruption the pandemic has triggered, it’s critical to study from the expertise. The phrases of reference for the Royal Commission of Inquiry into New Zealand’s COVID response have a powerful deal with managing future pandemics.
This aim is necessary as there are a number of infectious brokers with pandemic potential. Avian influenza is a rising concern at current.
In our view, the best lesson from COVID is that elimination must be the default selection for future pandemics. A key precedence is fast elimination at supply, adopted by interrupting the unfold to provide time to develop efficient vaccines and different prevention measures.
The expensive lesson from COVID: why elimination must be the default world technique for future pandemics
As we enter the fourth yr of the pandemic, there’s trigger for optimism.
Evidence helps a suppression technique that minimises the frequency of infections and their dangerous penalties. Delivering such a method is prone to be more practical, equitable and sustainable if mixed with a broad programme which treats all critical respiratory infections extra like COVID.
While the specter of future pandemics could also be growing, we now have the flexibility to get rid of them. This is a big advance in world well being safety.
