The condition has put significant strain on patients and society — at a global economic cost of about $1 trillion a year, a new report estimates.

About 400 million people worldwide have been afflicted with long Covid, according to
a new report by scientists and other researchers who have studied the condition. The team estimated that the economic cost — from factors like health care services and patients unable to return to work — is about $1 trillion worldwide each year, or about 1 percent of the global economy.

About 6 percent of adults globally have had long Covid.
The authors evaluated scores of studies and metrics to estimate that as of the end of 2023, about 6 percent of adults and about 1 percent of children — or about 400 million people — had ever had long Covid since the pandemic began. They said the estimate accounted for the fact that new cases slowed in 2022 and 2023 because of vaccines and the milder Omicron variant.
They suggested that the actual number might be higher because their estimate included only people who developed long Covid after they had symptoms during the infectious stage of the virus, and it did not include people who had more than one Covid infection.

The authors cited studies suggesting that
only 7 percent to 10 percent of long Covid patients fully recovered two years after developing long Covid. They added that “some manifestations of long Covid, including heart disease, diabetes, myalgic encephalomyelitis and dysautonomia are chronic conditions that last a lifetime.”
The consequences are far-reaching, the authors wrote: “Long Covid drastically affects patients’ well-being and sense of self, as well as their ability to work, socialize, care for others, manage chores and engage in community activities — which also affects patients’ families, caregivers and their communities.”
The report cited estimates that between
two million and four million adults were out of work because of long Covid in 2022 and that people with long Covid were
10 percent less likely to be employed than those who were never infected with the virus.
