Doctors and scientists are on an urgent quest to understand and treat the puzzling phenomenon of "long Covid", also known as post-Covid syndrome, where people who have had Covid-19 experience lingering symptoms more than a month after recovery.

The latest research by the Mayo Clinic shows that some patients diagnosed with the syndrome experience mood disorders, fatigue and perceived cognitive impairment. These symptoms have negatively affected their return to work and ability to resume normal activities, the study researchers reported.

A worrying fact is that the majority of patients in the study had no pre-existing comorbidities prior to their Covid-19 infection, said Professor Greg Vanichkachorn, medical director of Mayo Clinic's Covid-19 Activity Rehabilitation Program (CARP), and first author of the study.
