New Zealand’s zero Covid strategy is becoming unsustainable

New Zealand has done remarkably well over the past 18 months at protecting its citizens from the worst of the Covid pandemic – better than almost any other country in the world. Only 26 people have died of Covid in the country, after it has aggressively locked down at the first sign of a case and closed off its borders to the rest of the world. But as we have recently learned in Afghanistan, an exit strategy can easily undermine all your previous achievements. New Zealand is now in a very difficult situation. It is currently facing its first outbreak of the Delta variant, but only a small proportion of its population is immunised. This week the country announced that its latest lockdown would be extended again.

Will Covid turn into the common cold?

Many experts and modellers thought that the 19 July reopening would be a disaster. So far, that has not been the case. Daily case numbers actually started falling within days after 19 July, although that was far too soon to have been caused by anything to do with ‘freedom day’. The question now is how the pandemic will play out for the rest of this year and the next? In trying to understand this, we need to understand some important things about the biology of coronaviruses and their interaction with their hosts: us. Sars-CoV-2, the virus that causes Covid, is not going away. Like other coronaviruses, it will likely infect us all repeatedly throughout the rest of our lives, probably about once every five years.

How concerned should we be by the Indian variant?

In recent weeks there has been a lot of new-found optimism in Britain with regards to Covid: case numbers, hospitalisations and deaths have dramatically fallen and the vaccine roll out continues at pace. The virus has now been overtaken as the main cause of death in England and Wales for the first time since autumn. But the pandemic continues to grow, and nowhere more so is this the case than India. Its hospitals are overrun. Crematoriums are overwhelmed and the first of nine planes from Britain set off on Sunday night to provide oxygen, ventilators and aid. Why should it be surging now? One of the theories behind this explosion is a new variant of coronavirus (B.1.617).
