According to a follow-up study published by the medical journal the Lancet has said that two years after getting infected with coronavirus half of people hospitalized with the virus have at least one symptom.
The Lancet Respiratory Medicine in a study said proofs shows that a considerable proportion of people who have recovered from COVID-19 have long-term effects on multiple organs and systems.
“Regardless of initial disease severity, COVID-19 survivors had longitudinal improvements in physical and mental health, with most returning to their original work within 2 years; however, the burden of symptomatic sequelae remained fairly high,” the Lancet said in the summary of its study.
“COVID-19 survivors had a remarkably lower health status than the general population at 2 years. The study findings indicate that there is an urgent need to explore the pathogenesis of long COVID and develop effective interventions to reduce the risk of long COVID,” it said.
It stated that long Covid could persist for up to two years after acute infection, indicating that ongoing longitudinal follow-up is critical to better characterize the natural history of long Covid and to determine when Covid survivors will fully recover.
The Lancet said, “Future studies should further explore the pathogenesis of long COVID and develop effective intervention strategies to reduce the risk of long COVID.”
According to the medical journal, given the large number of people who have recovered from COVID-19 to date, the sequelae after recovery from acute COVID-19 are undoubtedly a major health concern and may result in a significant medical and socioeconomic burden.
A UK study published in late April found that only one in every four people had fully recovered from Covid a year after being hospitalised with the disease, raising concerns that Covid could become a common condition in the future.
“The limited recovery from five months to one year after hospitalisation in our study across symptoms, mental health, exercise capacity, organ impairment and quality-of-life is striking,” study co-leader Rachel Evans of the National Institute for Health and Care Research had said.
The most common long-Covid symptoms were fatigue, muscle pain, poor sleep, slowing down physically and breathlessness.
“Without effective treatments, long Covid could become a highly prevalent new long-term condition,” said study co-lead Christopher Brightling of the University of Leicester.
