Another study, and analysis courtesy of epidemiologist Katelyn Jetelina:

A recent study pooled more then 54 long Covid studies (which included a total of 1.2 million people) and found that 6% of individuals who had symptomatic SARS-CoV-2 infection experienced long Covid in 2020 and 2021. This is consistent with a massive study in Sweden (2020-2021) that found the proportion receiving a long Covid diagnosis was 1% among individuals not hospitalized for their COVID-19 infection, 6% among those hospitalized, and 32% among those treated in the ICU.

Today, the U.K. estimates that 3% of the general population has long Covid. In the U.S., the population-level burden of long Covid has been historically difficult to grasp. But in August 2022, the U.S. Census Bureau added four questions about long Covid to its Household Pulse Survey. What did they find?

• 16 million working-age Americans (aged 18 to 65) have long Covid today. This equates to ~8% prevalence. Of those, 2-4 million are out of work due to long Covid.

• The annual cost of lost wages is ~$170-$230 billion a year.

• The prevalence of severe long Covid is unequally distributed across race/ethnicity and age.
