In recent weeks, Australia, Vietnam and New Zealand have all announced that they are moving away from a zero-COVID strategy. In other words, they are moving away from trying to eliminate community transmission of the virus to suppressing it. This led to a number of “I told you so” editorials from people who preferred a more laissez-faire approach to the pandemic.
But Ruairi Brugha, an emeritus professor of public health and epidemiology, says there can be little doubt that countries that adopted a zero-COVID strategy saved thousands – if not hundreds of thousands – of lives. “The most important lesson,” he says, “is not to find and adhere to one strategy, but to steadily follow the science.” And the delta variant has certainly changed the science.
Is Boris Johnson facing his winter of discontent? The polls can tell you, but only if they ask the right question. We also take a look at tree planting and whether it really is a solution to the climate crisis.
