On May 11, 2023, a National Institutes of Health supported long-term study reported that among people who have had COVID-19, adults with obstructive sleep apnea were more likely to experience long-term symptoms suggestive of long COVID than those without the sleep disorder.

The research, which came from EHR data of more than 2.2 million Americans with COVID-19, suggests close monitoring after a COVID-19 infection may help adults with sleep apnea. The findings may also strengthen understanding of why some people are more likely to develop the post-viral syndrome after acute infection. The study was published in the journal SLEEP.
