(HealthDay News) — Persistent symptoms at 90 to 150 days after COVID-19 can be attributed to COVID-19 in 12.7% of patients, according to a study published in the Aug. 6 issue of The Lancet.
Aranka V. Ballering, from the University Medical Center Groningen in the Netherlands, and colleagues collected data from a multidisciplinary, prospective, population-based, observational cohort study examining the health and health-related behaviors of people living in the north of the Netherlands to assess the nature, prevalence, and severity of long-term symptoms related to COVID-19. Longitudinal dynamics of 23 somatic symptoms surrounding COVID-19 diagnoses were assessed between March 31, 2020, and Aug. 2, 2021; 76,422 participants completed 883,973 questionnaires. Of these, 4,231 participants with COVID-19 were matched to 8,462 controls.
The researchers found persistent symptoms, including chest pain, difficulties with breathing, pain when breathing, painful muscles, ageusia or anosmia, tingling extremities, lump in throat, feeling hot and cold alternately, heavy arms or legs, and general tiredness, in COVID-19-positive participants at 90 to 150 days after COVID-19 compared with before COVID-19 and compared with matched controls. These symptoms could be attributed to COVID-19 in 12.7% of patients, because 21.4 and 8.7% of COVID-19-positive patients and COVID-19-negative controls, respectively, had at least one of these symptoms, which increased to at least moderate severity at 90 to 150 days after COVID-19 diagnosis or a matched time point.
“We found that about one in every eight patients are affected by persistent symptoms after COVID-19. This finding shows that post-COVID-19 condition is an urgent problem with a mounting human toll,” the authors write.
