While we have estimates of how many people have died from COVID globally (which currently run at just under 7 million), its broader effects – including mental health deterioration due, for example, to the anxiety of getting infected or the isolation of lockdowns – have received less research attention.

More than three years into the COVID pandemic, both the virus and the measures taken to control its spread have affected people’s lives across the globe. But how can we fully quantify these effects?

While we have estimates of how many people have died from COVID globally (which currently run at just under 7 million), its broader effects – including mental health deterioration due, for example, to the anxiety of getting infected or the isolation of lockdowns – have received less research attention.

In a new study we’ve attempted to quantify how the COVID pandemic has affected global health using an international survey of the general public.

Health economists often quantify health using a metric known as the quality-adjusted life year (QALY). The idea is to assign a value to each year of a person’s life based on their overall health. A person in full health gets a score of one and those who are very ill close to zero.
