A Fifth Of Asymptomatic Covid Patients Develop Long Covid: Study

The analysis by non-profit FAIR Health encompassed insurance claims from 1.96 million Americans -- the largest population of patients ever studied for long Covid -- from February 2020 to February 2021.

Almost a fifth of Covid patients without symptoms went on to experience conditions consistent with long Covid a month after their initial diagnosis, according to a huge study published Tuesday. The analysis by non-profit FAIR Health encompassed insurance claims from 1.96 million Americans -- the largest population of patients ever studied for long Covid -- from February 2020 to February 2021. "Even as the Covid-19 pandemic wanes, long-haul Covid persists as a public health issue affecting many Americans," said FAIR Health's president Robin Gelburd. "The findings in our new study shed significant light on this emerging issue for all individuals who have long-haul COVID, as well as for policy makers, providers, payors and researchers."
