Correlates of symptomatic remission among individuals with post-COVID-19 condition 2023 Perlis et al

Abstract

Importance
Post-COVID-19 condition (PCC), or long COVID, has become prevalent. The course of this syndrome, and likelihood of remission, has not been characterized.

Objective
To quantify the rates of remission of PCC, and the sociodemographic features associated with remission.

Design
16 waves of a 50-state U.S. non-probability internet survey conducted between August 2020 and November 2022

Setting
Population-based

Participants
Survey respondents age 18 and older

Main
Outcome and Measure PCC remission, defined as reporting full recovery from COVID-19 symptoms among individuals who on a prior survey wave reported experiencing continued COVID-19 symptoms beyond 2 months after the initial month of symptoms.

Results
Among 423 survey respondents reporting continued symptoms more than 2 months after acute test-confirmed COVID-19 illness, who then completed at least 1 subsequent survey, mean age was 53.7 (SD 13.6) years; 293 (69%) identified as women, and 130 (31%) as men; 9 (2%) identified as Asian, 29 (7%) as Black, 13 (3%) as Hispanic, 15 (4%) as another category including Native American or Pacific Islander, and the remaining 357 (84%) as White. Overall, 131/423 (31%) of those who completed a subsequent survey reported no longer being symptomatic. In Cox regression models, male gender, younger age, lesser impact of PCC symptoms at initial visit, and infection when the Omicron strain predominated were all statistically significantly associated with greater likelihood of remission; presence of ‘brain fog’ or shortness of breath were associated with lesser likelihood of remission.

Conclusions and Relevance
A minority of individuals reported remission of PCC symptoms, highlighting the importance of efforts to identify treatments for this syndrome or means of preventing it.
