Long COVID-19 and Health-Related Quality of Life of Mild Cases in Korea: 3-Months Follow-up of a Single Community Treatment Center.

Cardiopulmonary symptoms improved over time but constitutional, neurological, neuropsychiatric symptoms remained. Patients with neuropsychiatric symptoms (anxiety and insomnia) reported the worst HRQoL. Female sex, metabolic disease, and anxiety during the acute COVID-19 phase were associated with long COVID. Observations of long-term symptoms of COVID-19 with decline in HRQoL and integrated research in COVID-19 survivors are warranted.
