We are nowhere near the end of the pandemic. Delta will not be the last highly transmissible variant. Large unvaccinated groups and the unchecked spread of the virus around the world raise the prospect of further mutations, possibly evading today’s vaccines, that will create new waves everywhere. Yet COVID-19 is also a forerunner of more, and possibly worse, pandemics to come. Scientists have repeatedly warned that without greatly strengthened proactive strategies, global health threats will emerge more often, spread more rapidly, and take more lives. Together with the world’s dwindling biodiversity and climate crisis, to which they are inextricably linked, infectious disease threats represent the primary international challenge of our times.
