Study highlights a rapidly increasing patient population with long COVID and lack of treatments

A new UK study of more than 2,000 patients after hospitalization with COVID-19 presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon 23-26), and published in The Lancet Respiratory Medicine shows that, one year after having COVID-19, only around one in four patients feel fully well again.
