said Athena Akrami, a neuroscientist at University College London in the UK, and senior author of the study.
People who seem to have these complications are the ones older than 50 years of age and individuals with pre-existing co-morbidities like

The most commonly reported
The researchers have designed a web-based survey that helps analyze the symptom profile and time frame of post-covid health complications for the new study.
To characterize the cases more accurately, they restricted the survey only to the 3,762 eligible participants from 56 countries who had clinically confirmed or suspected COVID-19. All of them experienced post-covid health issues for more than 28 days.
The survey was made possible by COVID-19 support groups like Body Politic, Long COVID Support Group, Long Haul COVID Fighters, and socialmedia like Twitter and Facebook. The data were collected from September 6, 2020, to November 25, 2020.
Highlights of the Case
Based on the responses received, the researchers reported that
- The probability of post-covid complications lasting beyond seven months was 91.8%
- Around 96% of the respondents had health issues beyond three months, 65% had them for about six months
- People who recovered in less than three months showed a peak in the average number of symptoms at week two, whereas those who did not recover within three months showed the same peak at the second month
- More than 200 symptoms were associated with the post-covid syndrome. The participants experienced an average of 56 symptoms
- An average of about 14 symptoms was experienced by respondents who had health issues for over six months
- The most prevalent symptoms were fatigue, post-exertional malaise (which worsens after physical or mental exertion), and cognitive dysfunction.
- Other symptoms experienced by the participants were visual hallucinations, tremors, itchy skin, heart palpitations, shingles, memory loss, blurred vision, diarrhea, tinnitus, changes to the bladder control issues, menstrual cycle, and sexual dysfunction
“For the first time, this study shines a light on the vast spectrum of symptoms, particularly neurological, prevalent and persistent in patients with long Covid,” highlighted Akrami.
The study has some limitations, including its retrospective nature and the risk of bias as the survey was distributed in online support groups. Yet, based on the significant findings, the researchers now emphasize the need for clinical guidelines to assess long covid cases.
The complete research report of this study was published in the Lancet journal EClinicalMedicine.
