Recent research based on information from 3,762 Long Covid sufferers shows most still have symptoms after 7 months.
The study uses patient-driven research and is based on a survey created by a team of patients with COVID-19 who are members of the Body Politic online COVID-19 support group. The group conducted its first survey in April 2020 and issued a subsequent report in May 2020. Participants were not randomly selected. They are people suffering Long Covid that volunteered to take part.
The global survey was open to individuals 18 years of age and older who experienced symptoms consistent with Covid-19, including those with and without positive SARS-CoV-2 diagnostic or antibody test results. Respondents first had symptoms between December 2019 and May 2020.
More than half of respondents (57%) did not seek hospital-based care for their initial symptoms. 35% visited an ER or urgent care clinic but were not admitted to a hospital, and 8% of respondents were hospitalised. Unlike critically ill Covid patients, the majority of the patients in this group were young. 60% were aged between 30 and 49, and another 27% were aged between 50 and 59. Only 13% were older than 59.
Overall, the probability of symptoms lasting 35 weeks (8 months) was 91.8% among the survey group. Of the total, 257 (6.8%) recovered after day 28 of illness, and 3,505 (93.2%) were still experiencing symptoms at the time of survey completion.
The most commonly reported long symptoms at 7 months were fatigue (80%), post-exercise malaise (73%), cognitive dysfunction (58%), sensorimotor symptoms (56%), headaches (54%) and memory issues (51%). In addition, between 30%-50% of respondents were experiencing the following symptoms after 6 months of symptoms: insomnia, heart palpitations, muscle aches, shortness of breath, dizziness and balance issues, sleep and language issues, joint pain and tachycardia.
The report said that most had not returned to previous levels of work by 6 months.
