Editorial: COVID is here to stay – countries must decide how to adapt
As we enter the third year of the pandemic, countries need to find ways of living with SARS-CoV-2 while minimizing its harms.From a pandemic perspective, 2022 seemed poised to begin with a hefty dose of déjà vu, with COVID-19 cases on the rise in many countries in the lead-up to the new year.
The emergence of the Omicron variant last November highlighted the ongoing challenges of life with SARS-CoV-2. Some countries were already facing surges in the highly transmissible Delta variant, but vaccines and prior infection conferred relatively high levels of protection against Delta, particularly against severe disease.
With infection rates soaring around the globe and many countries still unable to access adequate vaccine supplies, more SARS-CoV-2 variants of concern will continue to emerge. And, as Omicron has illustrated, the ability to predict what course those variants will take becomes more difficult as the complexities of viral evolution and pre-existing immunity complicate the models that have previously been used to anticipate the course of the pandemic.
