Lancet study says long Covid has more than 200 symptoms
London, Jul 15: Patients who experience long Covid can report more than 200 symptoms across 10 organ systems, according to a study published in the Lancet’s journal EClinicalMedicine on Thursday.
The study, led by University College London (UCL) scientists together with a patient-led research collaborative, found the most common symptoms of long-term COVID effects as fatigue, post-exertional malaise (the worsening of symptoms after physical or mental exertion), and cognitive dysfunction, often called brain fog.
Of the diverse range of symptoms, others included: visual hallucinations, tremors, itchy skin, changes to the menstrual cycle, sexual dysfunction, heart palpitations, bladder control issues, shingles, memory loss, blurred vision, diarrhoea, and tinnitus.
While there has been a lot of public discussion around long COVID, there are few systematic studies investigating this population; hence relatively little is known about its range of symptoms, and their progression over time, the severity, and expected clinical course (longevity), its impact on daily functioning, and expected return to baseline health, said Dr Athena Akrami, neuroscientist at the Sainsbury Wellcome Centre at UCL and senior of the study published in the Lancet's EClinicalMedicine'.
In this unique approach, we have gone directly to long haulers' around the world in order to establish a foundation of evidence for medical investigation, improvement of care, and advocacy for the long COVID population. This is the most comprehensive characterisation of long COVID symptoms, so far, she said.
For the study, patient researchers connected through the Body Politic online COVID-19 support group and created a web-based survey designed to characterise the symptom profile and time course in patients with confirmed or suspected long COVID, along with the impact on daily life, work, and return to health.
With responses from 3,762 eligible participants from 56 countries, the researchers identified a total of 203 symptoms in 10 organ systems; of these, 66 symptoms were tracked for seven months.
The research team, who have all had or continue to have long COVID, are now calling for clinical guidelines on assessing long COVID to be significantly widened beyond currently advised cardiovascular and respiratory function tests to include neuropsychiatric, neurological, and activity intolerance symptoms.
The authors also advocate that a national screening programme, accessible to anyone who thinks they have long COVID, should be undertaken.
Given the heterogeneous and diverse make-up of symptoms that affect multiple organ systems, it is only by detecting the root cause that patients will receive the correct treatment, they note.
Dr Akrami added: 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.
Memory and cognitive dysfunction, experienced by over 85 per cent of respondents, were the most pervasive and persisting neurologic symptoms, equally common across all ages, and with substantial impact on work. Headaches, insomnia, vertigo, neuralgia, neuropsychiatric changes, tremors, sensitivity to noise and light, hallucinations (olfactory and other), tinnitus, and other sensorimotor symptoms were also all common, and may point to larger neurological issues involving both the central and peripheral nervous system.
The survey was open to those aged 18 or over who had experienced symptoms consistent with COVID-19, including those with and without a positive SARS-CoV-2 test. It consisted of 257 questions.
In order to characterise long COVID symptoms over an extended duration, analysis of survey data was limited to respondents with illnesses lasting longer than 28 days and whose onset of symptoms occurred between December 2019 and May 2020, allowing analysis of symptoms from week one to month seven.

Congress using hijab issue to pacify minority anger, alleges Karnataka LoP R Ashoka
Bengaluru: Leader of Opposition in the Assembly R. Ashoka has accused the Congress government of using the hijab issue to placate what he described as discontent among minority voters after the Davanagere by-election.
In a post on X on Wednesday, Ashoka alleged that the state government, instead of addressing issues such as price rise, corruption, farmers’ distress and law and order, was attempting to retain its minority vote base by reviving the hijab issue.
Referring to the 2022 dress code introduced by the BJP government, which prohibited hijab in schools and colleges, Ashoka said the Karnataka High Court had upheld the policy and emphasised the importance of discipline in educational institutions.
He questioned the Congress government’s move to revisit the issue and asked whether setting aside the court-backed policy to benefit one community could be described as secularism.
Ashoka further alleged that while the government was willing to permit hijab, it continued to prohibit saffron shawls.
He accused the government of dividing students on religious lines rather than treating schools and colleges as spaces of equality.
Drawing a comparison with Mamata Banerjee’s government in West Bengal, Ashoka claimed that excessive appeasement politics had harmed the state and warned that the Congress in Karnataka could face a similar political response.
He said voters in Karnataka would teach the Congress a lesson for what he termed “vote-bank politics” and for compromising constitutional and judicial principles.
