The health problems faced by Long Covid sufferers need to be addressed urgently, say six women in Britain who have just published an open letter drawing attention to the plight of those experiencing persistent symptoms long after being infected by SARS-CoV-2.
The six women, who are themselves Covid long haulers, and are from diverse professional disciplines, say that the persistent symptoms following SARS-CoV-2 infection “are now one of the most pressing clinical and public health phenomena to address”.
The new open letter is yet another attempt by long haulers to raise awareness about Long Covid and spark action.
About 300,000 people in Britain have reported Covid symptoms lasting for more than a month, and 60,000 say they have been ill for more than three months.
Long haulers have formed support groups and have launched grassroots campaigns to bring #LongCovid to visibility.
The authors of the new open letter are calling for a “nuanced, patient-focused approach” – one that incorporates wide-ranging investigations of potential post-viral conditions and also recognises the pathogenesis of SARS-CoV-2 as specific in its own right.
“We need to avoid the severity or prevalence of ‘Long Covid’ being downplayed – whether for political purposes, privileging the claims that the economy is at odds with reducing levels of infection, or for fear of inadequately resourced healthcare systems,” Elisa Perego et al. write.
“We need to ensure the public knows about the potential ‘Long Covid’ consequences of infection when they are balancing the risks of exposure to SARS-CoV-2.”
The causes of Long Covid are unknown, the effects can be debilitating, and the percentage of patients affected is unclear, though likely significant, the letter’s authors say.
Doubts and imprecision about the meaning of the term Long Covid remain and an epidemiological definition is needed, they add.
The main symptoms reported over eight weeks were shortness of breath, tightness in the chest, fatigue, chills or sweats, body aches, a dry cough, an elevated temperature (98.8–100), headaches, gastrointestinal issues, and brain fog.
About 91% of respondents said they hadn’t fully recovered. They had, on average, suffered symptoms for forty days.
The list of symptoms suffered by long haulers is lengthy. They range from extreme thirst, swollen lymph nodes, weight loss, hair loss, exhaustion, and joint pain to neurological problems such as numbness and muscle spasms.
People also suffer hallucinations and delusions, personality changes, panic attacks, dizziness, sensitivity to light and sound, eczema, blurred vision, stuttering, slurred speech, sleep disorders, and an increased heart rate.
Other problems include fevers that last for months, impaired short-term memory, a poor sense of body movement and position, heat intolerance, difficulty standing, menstrual changes, tinnitus, persistent nausea, and newfound food sensitivities.
Loss of the sense of taste and/or smell is very common and the disorder that has become known as Covid toe (painful red or purple lesions) has been much publicised.
The ZOE Covid Symptom Study, conducted in the UK and instigated by doctors and scientists working in partnership with the health science company ZOE, has produced figures suggesting that 12% of people in the country who contracted Covid-19 are still unwell after a month. One in 200 people said they had been suffering symptoms for more than 90 days.
According to information gathered on the Covid Symptom Study app, which tracks sufferers regardless of whether they have had a test for SARS-CoV-2, about 300,000 people in Britain have reported symptoms lasting for more than a month, and 60,000 have been ill for more than three months.
Stephen Davis from PlanetEarth HD Documentaries tweeted recently – six months after he contracted Covid-19 – that he was suffering the symptoms of postural orthostatic tachycardia syndrome (POTS) along with skin flushing, headaches, tachycardia, and numbness.
One of the co-authors of the open letter, Rachel Pope, tweeted about the severe pain in her heart and kidneys:
In an opinion piece published in the Los Angeles Times on July 9 David Lat, who is the founding editor of the legal news website Above the Law, talks about his “near-death experience with Covid-19”.
Lat spent 17 days in hospital, including six days on a ventilator. He had a lingering cough for two months.
“Recovering from a severe case of Covid-19 is not like switching a light on or off,” Lat wrote. “It’s more like a dimmer switch, where the light gets brighter, then darker, then brighter again …
“Before I came down with Covid-19, I could run for miles. After returning from the hospital, I needed a wheelchair to go even half a block.”
Lat wrote that he had improved dramatically since then, and many of his issues had resolved themselves.
“I graduated from the wheelchair to walking short distances to walking a few miles. My voice, hoarse because of how the ventilator damaged my vocal cords, slowly returned. I regained the 20 pounds I had lost (and then some). My cough, so forceful it made my chest and shoulders ache, finally went away. I can laugh again.
“But I’m still not back to normal, if normal means the way I was before Covid-19. I can’t jog – to say nothing of run – for more than a few minutes. I took a gallon of milk out of the refrigerator the other day for my son, and it felt like a 30-pound barbell. I tried reading a book about fire engines to him, and my voice, while much better than before, can’t make the “whoo-whoo” noise of a fire truck.”
One case referred to in the Body Politic Covid-19 Support Group’s newsletter that was published on August 18 is that of Morgan, a support group member who worked in tech prior to becoming ill.
After more than four months of illness, she was still struggling with a host of debilitating neurological symptoms, including the inability to add simple numbers. “I’m incapable of sustained thinking, which for me means I’m incapable of working,” Morgan wrote.
“Demanding that my brain perform at this point could slow my recovery or leave me with limited capabilities. I have always been a knowledge worker, so thinking about that outcome is frightening.”
The newsletter’s authors state: “Long-term illness alters relationships, shrouds the future in uncertainty, and in too many cases, creates devastating economic hardship.”
They say support group members have been laid off or fired or have had to turn down job offers because of their myriad lingering symptoms.
“Some have resorted to working part-time, but worry about their ability to live off of this limited income for months or years to come. Many members, including healthcare workers, suspect that they contracted the virus while on the job. In quite a few of these cases, eligibility for workers comp is thwarted by false negative test results.”
The new open letter, which was published on the Wellcome Open Research Platform on September 24, and is entitled Why the Patient-Made Term ‘Long Covid’ is needed, was authored by Elisa Perego from the Institute of Archaeology at University College London; Felicity Callard from the School of Geographical and Earth Sciences at the University of Glasgow; Laurie Stras from the School of Music, Humanities and Media at the University of Huddersfield; Barbara Melville-Jóhannesson from the Creative Informatics department at the University of Edinburgh; Rachel Pope from the Archaeology, Classics and Egyptology department at the University of Liverpool; and Nisreen Alwan, a medical doctor and associate professor from the Faculty of Medicine at the University of Southampton.
“We’ve tried here to bring together our expertise from the humanities, interpretive social sciences, arts, medicine and public health, science policy, patient involvement, and ethics in research,” the authors say.
Perego, Callard, Stras, Melville-Jóhannesson, Pope, and Alwan say that the personal, economic, and social costs of Long Covid are unfathomable and include screening; medical, rehabilitative and social care; and the costs associated with long-term disability, including lost productivity.
“Research indicating sequelae, even in asymptomatic/pauci-symptomatic cases, suggests screening and treatment may be needed for millions. The impact on already marginalised/minoritised communities will be particularly profound,” they add.
They say there is a need for greater specificity in measuring symptom duration, fluctuation, overall functionality, and quality of life as compared with pre-infection.
“Understanding ‘Long Covid’ is also crucial for prevention, and will help determine pandemic control policies,” they write.
Perego et al. say medical professionals, the media, and the wider community need to be sensitive to the trauma experienced by patients suffering from Long Covid.
“Some were left untended, to die at home; many were misunderstood or had their symptoms reduced to anxiety. Some have been caring for ill – or dying – family and friends, and many have lost jobs or are under threat of losing their livelihoods, medical insurance, or visa status.”
On August 24, Perego participated in a meeting with World Health Organisation officials that was called to address the challenges of long-term Covid-19 effects. About sixty long haulers from numerous countries, led by LongCovidSOS, a patient-led advocacy group in the UK, attended the online meeting.
Pauline Oustric from the French campaigning group #Apresj20 spoke about Long Covid support groups and campaigning initiatives that have emerged across Europe. She called for recognition, research, and rehabilitation, and for better communication about Long Covid. She urged the WHO and national governments to warn populations of the risks of Long Covid as a matter of urgency.
One of the long haulers attending the meeting with the WHO was Hannah Davis from the US, who told Brianna Sacks at BuzzFeed News that there were weeks when she couldn’t even remember how to send a text message.
“I feel like I have a brain injury,” Davis told BuzzFeed News. “I have a hard time remembering who I was. It was hard to remember I had to feed myself a couple times a day.”
Perego et al. say Long Covid is “a helpful and capacious term” that is needed to address the key medical, epidemiological, and socio-political challenges posed by diverse symptoms that persist beyond four weeks “after symptom onset that is suggestive of Covid-19”.
They add: “An international movement of patients (which includes all six authors) brought the persistence and heterogeneity of long-term symptoms to widespread visibility.
“The same grassroots movement introduced the term ‘Long Covid’ (and the cognate term ‘long-haulers’) to intervene in relation to widespread assumptions about disease severity and duration.”
The term Long Covid is now used in scientific literature, the media, and in interactions with the WHO, Perego et al. point out.
Perego et al. say that two other definitions, in addition to an epidemiological definition of Long Covid, need to be established: a “clinical case definition of Covid-19, which does not solely rely on laboratory confirmation”, and a “sophisticated definition for recovery that accounts for relapsing illness”.
Patient-led surveys made visible the diversity and persistence of Long Covid symptoms, Perego et al. say.
“Scientists do not yet know what causes long-term symptoms and incidence remains uncertain,” the women write. Case studies, they say, indicate that 10–87% of patients present persistent symptoms or fail to return to their health baseline three weeks after onset.
“These figures, however, derive from heterogeneous study designs and samples.”
There are vastly variable clinical manifestations of Long Covid, Perego et al. say.
“It may incorporate several conditions with different aetiologies and more than one mechanism, even in the same patient. Effects in multiple organs have been documented. On-going fatigue appears common.”
Perego et al. also say that, by deconstructing the current “mild-versus-severe” dichotomy, Long Covid “underlines that hospitalisation is an imperfect indicator of severity, even if has been used as such in studies”.
They add: “To rely on hospitalisation as a demarcation of severity creates skewed samples, including poor representation of younger/paediatric patients.
“In any case, persistent symptoms impairing an individual’s usual function and quality of life should not be called ‘mild’.”
Nature and duration of Covid-19 illness
Perego, Callard, Stras, Melville-Jóhannesson, Pope, and Alwan say that, while Long Covid patients have been provisionally defined as those who have not recovered within four weeks from symptom onset, “the point at which Covid-19 moves out of its acute phase remains unclear, and may vary in different patients”.
Duration and final outcomes of, and recovery from, Long Covid are also unclear, they say.
“Further research needs to address the complex host-pathogen interaction. While similarities between some ‘Long Covid’ symptoms and symptoms from conditions such as myalgic encephalomyelitis/chronic fatigue syndrome and dysautonomia need to be investigated, there is a risk of prematurely framing studies of ‘Long Covid’ through other diseases.
“This might downplay emerging phenomena specifically linked to Covid-19 – such as the range of SARS-CoV-2 action via ACE2 receptors widespread in the body, and the temporally and spatially complex immune response to the virus – thereby missing thresholds for early intervention.”
Lives turned upside down
The Atlantic’s science writer Ed Yong interviewed nine long haulers for an article published in June. One of them was Vonny LeClerc, a Glasgow-based journalist who told Yong that, on day 66 after she first started feeling shivery and flushed, she was still experiencing waves of symptoms.
“Before this, I was a fit, healthy 32-year-old,” LeClerc told Yong. “Now I’ve been reduced to not being able to stand up in the shower without feeling fatigued. I’ve tried going to the supermarket and I’m in bed for days afterwards. It’s like nothing I’ve ever experienced before.”
LeClerc said SARS-CoV-2 had ruined her life. “Even reading a book is challenging and exhausting. What small joys other people are experiencing in lockdown – yoga, bread baking – are beyond the realms of possibility for me,” she told Yong.
Alice Thomson wrote in an article published in The Sunday Times in Britain on September 23 that, six months after her Covid-19 symptoms started, she still can’t recognise smells.
“I still can’t tell the difference between the smell of an overripe banana or lavender. I can distinguish petrol but not gas, dog mess but not roses, bacon but not freshly cut grass. Everything else smells of burnt condensed milk,” she wrote.
Thomson still has her sense of taste, but feels slightly breathless when she goes for a run and finds that she bruises more easily than before.
“I have friends who haven’t been so lucky. We discuss symptoms and they vary wildly,” she wrote.
“Several have purple toes, two have hair loss another gets random rashes. A few have fared far worse. One friend, who’s 47, can still barely get out of bed 185 days after catching the virus; she has a constant high temperature, heart palpitations, body aches, chest pains, blue fingers and amnesia; at times she thinks she is going mad.
“A year ago we were running together in Hyde Park; now she can’t stir her soup. Her 75-year-old mother-in-law has moved in to nurse her and look after the children.”
Sandeep Lamba, from Gurgaon in India, is 26 and, before he contracted Covid-19, he was a competitive runner and played cricket and football. Now he cannot run any more. “I tried it once, but my heart started racing,” he told Changing Times.
Lamba is also suffering from severe anxiety, which strikes mostly after 6 p.m., but can occur during the day and last for 24 hours or more. He is now receiving distance reiki sessions, which are helping. He doesn’t want to get caught up in a cycle of coming on and off tranquillisers.
The anxiety, which began after Lamba was declared “recovered” (having had a negative PCR test), has been going on for more than three weeks. His case of Covid-19 was mild, and lasted two weeks. He says he is going through a worse time now than while he was SARS-CoV-2 positive.
Long hauler Talya Varga says she is seeking “rehab, research, and recognition” for those living with Long Covid.
In August, opera singer Lee David Bowen, aged 49, told Rhys Williams, reporting for the Caerphilly Observer in Wales, that he was still suffering the long-term effects of Covid-19 six months after first showing symptoms.
“I had a few days last week where I thought I was over it. It feels like you’re getting better, but then the symptoms come back. It’s crafty,” he said.
“My singing voice is in good shape thankfully, but I’m shattered after I practise,” Bowen told Williams.
Bowen told Williams he had been suffering “punishing fatigue”, a persistent metallic taste in his mouth, and brain fog.
“My mouth tastes like I’ve sucked a bag of two-pence pieces. I’m eating spicier foods to mask the bitter taste,” Bowen said.
Bowen told Williams that everyday tasks such as making breakfast, or just getting out of the shower, were exhausting.
Cherie Antoinette is a nurse, actress, writer, and film producer from Atlanta in the US who produces a blog called Eat Pray Nurse. She tweeted frequently during her time as a Covid patient, which was, on occasion, extremely traumatic, and continues to share her experiences during her recovery.
She has been suffering from some insomnia and daily panic attacks. “I think it’s because my body remembers how scary nights were. Deep breathing has worked wonders. I’m trying to find a happy medium between relaxed and oversedated,” she tweeted.
Ironically, Cherie Antoinette says that she feels better now than she did before Covid. “Adding vitamins and drinking tea daily, decreasing my stress, and eliminating alcohol and caffeine have that effect.”
Although she was healthy, she says, she wasn’t taking care of her mental or spiritual well-being. “That’s not to diminish anyone else’s recovery from Covid. We all have our own journey. For me it was an eye-opening moment that I could do better,” she tweeted.
Paul Garner, who is a professor of infectious diseases at the Liverpool School of Tropical Medicine and director of the Centre for Evidence Synthesis in Global Health, wrote an opinion piece for the BMJ (British Medical Journal), in which he describes the seven-week “roller coaster of ill health, extreme emotions, and utter exhaustion” he suffered after being infected with SARS-CoV-2.
He described how the illness, which began in mid-March, went on and on: “The symptoms changed, it was like an advent calendar, every day there was a surprise, something new. A muggy head; acutely painful calf; upset stomach; tinnitus; pins and needles; aching all over; breathlessness; dizziness; arthritis in my hands; weird sensation in the skin with synthetic materials.
“Gentle exercise or walking made me worse – I would feel absolutely dreadful the next day.”
Garner is still suffering symptoms. He tweeted recently about exercise.
Garner was one of the long haulers who, on September 3, participated in an online webinar hosted by the BMJ about the diagnosis, management, and prognosis of Long Covid. Nikki Nabavi reports on the webinar in an article for the BMJ, published on September 7.
GPs and patients need multidisciplinary guidance, Garner says. “There is a desperate need for good guidelines and advice right now.
“We need specialists working together in networks getting good guidance out about how to investigate heart conditions … Who should be having echos [echocardiograms], for example.”
Garner says people need to be realistic about the time needed for convalescence. “If you’ve got someone who’s 33, still in bed after six months with cardiac symptoms, they are not going to be back at work for at least six months.”
Tim Spector (pictured left), who is a professor of genetic epidemiology at King’s College London, and is leading the Covid Symptoms Study said: “If you’ve got a persistent cough, hoarse voice, headache, diarrhoea, skipping meals, and shortness of breath in the first week, you are two to three times more likely to get longer term symptoms.”
He said that patterns in the data suggested that Long Covid was about twice as common in women as in men.
He added: “We do seem to be getting different symptom clusters in different ages, so it could be that there is a different type in younger people compared with the over 65s.”
Nick Peters, who is a professor of cardiology at Imperial College London and a consultant cardiologist, talked about responses to a questionnaire launched in March.
“Out of the 20,000 or so patients in total who have variously dipped in and out of the questionnaire about 3,000 report thinking that they have had Covid-19.”
Of the 3,000, about 1,600 patients gave information about symptom longevity. “Out of those 1,600 about 300 report symptoms lasting longer than two months,” Peters said.
Garner said during the webinar that dealing with Long Covid was a full-time job: “This is a very bizarre disease and it affects you in waves; it’s like being battered, and you are repeatedly battered over a period of time. That was my first two months and the subsequent four months really has been lesser episodes, but still very fatigued.
“Navigating help is really difficult. Partly you are muddled in our own head; you can’t read things very well. There are multiple sources. The NHS [National Health Service] is pretty appalling in its advice around managing fatigue.”
Nisreen Alwan, whose symptoms started on March 20, also participated in the webinar. She said that profound fatigue was a very common Long Covid symptom. The other symptoms she cites include coughing, breathlessness, muscle and body aches, heaviness in the chest, skin rashes, palpitations, fever, headache, diarrhoea, and pins and needles.
Alwan did feel better after several weeks and did go back to work full-time for a few weeks “then crashed again”.
She says that a very common feature is the fluctuating or relapsing nature of the illness. “You feel you’ve recovered … and then it hits you back, and it’s a constant cycle of disappointment, not just to you, but to the people around you.”
For months, Alwan said, she was struggling to open the freezer or load the dishwasher.
Alwan said that, as someone with Long Covid, “you learn your patterns, and you learn what actually brings on this utter exhaustion, and you learn what brings on the other symptoms as well, and you try and avoid these things”.
She added: “I’m fairly driven, and I thought I could beat this virus. A friend told me to stop dominating the virus and start accommodating it. Once you start accepting that, it becomes a bit easier. You have to drop your baseline by 90%; you are a different person.”
Alwan says Long Covid cases should be incorporated into Covid-19 statistics.
“By the end of June, so more than three months into me not going back to my normal health, I was very frustrated by the fact that no one was counting us,” she said.
“There was no quantification, no surveillance, of people who have not recovered from Covid.”
The experiences of thousands of people were not being validated and believed, Alwan said.
Alwan is one of a group of doctors who wrote ‘From doctors as patients: a manifesto for tackling persisting symptoms of covid-19’, which was published in the BMJ on September 15.
The doctors said that tackling Long Covid would involve collaboration between politicians, healthcare services, public health professionals, scientists, and society.
They called for action on four fronts:
- research and surveillance,
- clinical services,
- patient involvement, and
- access to services.
The doctors said that persisting Covid-19 symptoms should be dealt with using a scientific methodology, without bias. Services need to be timely, and tailored to individuals, “and involve investigating and treating pathology, as well as the functional recovery of individuals”, they say.
They also said that patients must be involved in the commissioning of clinical services and the design of research studies. Clinical services should not unfairly discriminate against those with negative tests and a clinical diagnosis should be adequate for accessing any appropriate services, they added.
“Adherence to positive test results as a criterion for access to medical services or specific Covid-19 sick pay arrangements with employers is unacceptable in the context of a clinical diagnosis of Covid-19,” the doctors said.
In an article published in the BMJ on July 21, Ingrid Torjesen reported on the advice given to doctors by the National Institute for Health and Care Excellence (NICE) that graded exercise therapy might not be appropriate for treating post-viral fatigue in patients recovering from Covid-19.
NICE noted that its previous advice on managing chronic fatigue might not be appropriate for patients recovering from Covid-19 and acknowledged that it could also be out of date for other groups, Torjesen reported.
NICE’s guideline on myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) was published in 2007, many years before the current pandemic, NICE said, “and it should not be assumed that the recommendations apply to people with fatigue following Covid-19”.
Torjesen cites Garner’s case and says that he was “furious” when he read the 2007 NICE advice and the conclusions of the Cochrane review, which also supported exercise therapy and mentioned uncertainty about the side effects of adaptive pacing.
Garner realised early on in his recovery that he was experiencing post-exertional malaise. Every time he did any exercise that increased his heart rate, such as cycling or yoga, he found himself back in bed, Torjesen reported.
“Obviously, I know that if I increase my exercise I will be thrown back to bed,” Garner was quoted as saying. “What I struggle with as a highly driven medic is stopping myself overdoing it. That’s what I need help with – I don’t need help to increase my exercise.”
In an opinion piece published in the BMJ, Garner and three other long haulers wrote about how a self-help pacing group has helped them manage their Long Covid and gives them hope. The group, they say, is a safe space where they can talk about how they are doing and vent any frustrations.
The group members – Garner, general practice trainee Iulia Hammond, trainee anaesthetist Linn Järte, and director of the Gingerhead branding and design agency Helen Calder – meet weekly, online, for twenty minutes, and message each other when necessary.
The group, the long haulers say, has been a game changer. “Given the variety of our symptoms, we were all astounded that the management approaches that worked were so similar,” they wrote.
“We were all getting relapses; we jointly concluded that if we overdid it, these relapses were guaranteed, but the items of expenditure were different.”
The group members guide each other about how much exercise is advisable and how to get enough sleep.
“Managing pacing helps us prioritise our health,” the four wrote. “Two of us with children always put the children first, pushing through the fatigue. One runs her own business and needed to keep doing enough to protect her employees and not let down clients.
“Realising we had to be healthy to look after others assuaged the guilt of being less attentive to the children at home or placing heavier burdens on colleagues at work.”
The four long haulers all thought they were going to get better soon, but gradually became open to the probability that it might take much longer, perhaps twelve months.
“This was an important step and helped us make realistic goals, relieving the anxiety around the slow speed of recovery,” they wrote.
“All of us fear this illness might last for ever, but just saying it helps you feel better. We also witness each other improve, and are able to point this out, which gives a tremendous boost to our collective mood.
“As we learn to recover, we are not so lonely with our illness. We are healing, thanks to a little help from our friends.”
According to the Centers for Disease Control (CDC) in the US, 35% of people who have been diagnosed with Covid-19 are not back to normal after “recovery”.
If the current recorded number of recovered Covid-19 patients in the US is correct (4.48 million), this would mean there are about 1.56 million long haulers in the US alone.
Researchers who carried out a study in Germany found that 78 out of 100 patients studied had heart complications two months after they were diagnosed with Covid-19.
Valentina O. Puntmann MD et al. said that cardiac magnetic resonance (CMR) imaging revealed “cardiac involvement” in 78 patients. The most prevalent abnormality was myocardial inflammation, which was detected in 60 people.
“These findings indicate the need for ongoing investigation of the long-term cardiovascular consequences of Covid-19,” they said.
They added: “Our findings demonstrate that participants with a relative paucity of preexisting cardiovascular condition and with mostly home-based recovery had frequent cardiac inflammatory involvement, which was similar to the hospitalised subgroup with regards to severity and extent.”
The median time gap between the patient testing positive for SARS-CoV-2 and undergoing the CMR examination was 71 days.
Puntmann et al. said that, on the day of the CMR examination, 17 patients reported atypical chest pain, twenty reported palpitations, and 36 reported ongoing shortness of breath and general exhaustion.
Twenty-five of the 36 said they were suffering symptoms during “less-than-ordinary daily activities”, such as household chores.
Italian researchers found that more than 87% of patients they studied, who had been hospitalised, still had numerous symptoms after two months.
In their study, Angelo Carfì and two other doctors from the geriatrics department at the Gemelli University Hospital in Rome found that, of the 143 patients studied, who ranged in age from 19 to 84 years, 87.4% reported persistence of at least one symptom, particularly fatigue and dyspnea (shortness of breath).
Patients were assessed for an average of two months after the onset of the first Covid-19 symptom. At the time of the evaluation, only 18 patients were completely free of symptoms related to Covid-19, 32% had one or two symptoms, and 55% had three or more. None of the patients had fever or any signs of acute illness.
Worsened quality of life was observed among 44.1% of patients, Carfì et al. say. A high proportion of people still reported fatigue (53.1%), dyspnea (43.4%), joint pain, (27.3%) and chest pain (21.7%).
The doctors said the limitations of the study included the lack of information on symptom history before acute Covid-19 illness and the lack of details about symptom severity.
“Furthermore, this is a single-centre study with a relatively small number of patients and without a control group of patients discharged for other reasons. Patients with community-acquired pneumonia can also have persistent symptoms, suggesting that these findings may not be exclusive to Covid-19,” they added.
Four clinicians working for the Assistance Publique–Hôpitaux de Paris in France published a paper in Clinical Microbiology and Infection on July 22, in which they report seeing an average of thirty long haulers (“patients for whom symptoms have not completely subsided”) every week from mid-May. Most of the women were aged about forty, and women outnumbered men four to one.
During a survey of more than 1,500 patients conducted by by Indiana University Medical School researcher Natalie Lambert and Survivor Corps¹, 98 different long-term symptoms were reported weeks and even months after infection with SARS-CoV-2.
Main survey findings
• The number of symptoms experienced by long haulers is much greater than that given on the CDC’s website.
• The survey results suggest that long haulers frequently experience neurological, eye, and skin symptoms.
• Survivor Corps group members frequently report reaching out to primary care doctors
for help with lesser-known and painful symptoms, but find that some physicians are unable or unwilling to help patients manage these symptoms because of a lack of research.
• A total 26.5% of symptoms experienced by long haulers were described as painful.
In a report about “post-Covid-19 fatigue, post/Long Covid-19 syndromes, and post-Covid myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS)”, the honorary medical adviser to the ME Association, Charles Shepherd, writes that “as happens with ME/CFS”, there appears to be a significant female-to-male bias in people with Long Covid, but the bias is not as large as in the case of ME/CFS.
“Many are also previously fit young adults in their 20s, 30s and 40s,” Shepherd adds. “What is notable is the number who were regularly taking part in regular sporting activities, including running, and/or are health professionals.”
Perego et al. say that Long Covid may, mechanistically, include patients with symptoms variously deriving from direct viral damage, immune response damage, opportunistic bacterial infections, and post-viral/post-sepsis symptoms,
“Additional post-traumatic and mental health symptoms might interact with physiological symptoms in complex ways,” they write.
“‘Long Covid’ accounts for the possibility of persistent viral infection with low levels of viral shedding; protracted immune reaction; latency; or the presence of virus in reservoir organs or tissues.
“SARS-CoV-2 also appears to be able to reinfect, and to have the potential to precipitate new disease.”
Long Covid patients require prompt, multidimensional, diagnostic investigations and treatment – not least to rule out potentially life-threatening developments, Perego et al. say.
“Those who were not hospitalised, and those who were not tested or have negative PCR/antibody tests, must be able to access diagnostic and therapeutic services.”
Trauma and psychological symptoms are reported in both hospitalised and non-hospitalised survivors and need to be addressed sensitively, Perego et al. add.
“Differential diagnosis that does not reduce ‘Long Covid’ to psychological symptoms is crucial.”
The six women urge researchers and clinicians to tread a careful line that does not assume that symptoms are caused by anxiety; acknowledges that Covid-19 is frequently a traumatic experience; and considers many potential mechanisms in explaining mental health symptoms, including inflammatory responses and neurological damage.
Perego et al. also say there needs to be an adequate assessment of morbidity and mortality in ‘Long Covid’ cohorts, including in those who were not tested at the time of infection “or via effective serology screening, since testing is not exempt from pitfalls”.
Patients should be involved in the commissioning of research and clinical services, they add. “Many bring relevant expertise and some convene/own patient-led archives hosting extensive clinical data.”
There is potential for persistent illness to be caught up in political and medical misunderstandings and exploitation, Perego et al. say.
“The definition and treatment of complex phenomena (‘Long Covid’) that emerge in relation to an equally complex, currently not well understood disease (Covid-19), itself of contingent definition, are full of danger,” they write.
“We do not currently know whether all ‘Long Covid’ patients are indeed ‘post-viral’.
“While we acknowledge the importance of investigating comparisons with other diagnostic entities, we argue however against enfolding ‘Long Covid’ within other diagnoses.”
Perego et al. say there is a need for a label that is distinct from other phenomena related to earlier viral and other exposures, e.g. ME/CFS.
“We also question the term ‘Post-Covid Syndrome’. We believe it carries not only risks of misdiagnoses and mismanagement, but also of leaving those with persistent illness behind, especially in a post-vaccine world.”
There need to be collective responses to such questions as “Who will qualify for disability benefits/sick pay?” and “How will funds be allocated for research and treatment?” the six women say.
“Extensive involvement of ‘Long Covid’ patients has the best chance of ensuring that conceptualisation, investigation, and treatment of ‘Long Covid’ are attentive to the cultures, health systems, and discriminatory societies where patients live.
“‘Long Covid’ must not be understood as the outcome of biological processes alone.”
- Survivor Corps describes itself as “a grassroots movement connecting, educating and mobilising Covid-19 survivors with the medical, scientific, and academic research communities to help stem the tide of this pandemic and assist in the national recovery”.

The National Health Service (NHS) in England has announced a five-point package of measures to support Long Covid patients.
The chief executive of the NHS in England, Simon Stevens, announced that £10 million would be invested in helping to “kickstart and designate Long Covid clinics in every area across England”.
Stevens detailed the following measures:
- NHS England has asked NICE to issue new guidelines by the end of October about the “medical case definition” of Long Covid. This will include Covid-19 patients who have not been admitted to hospital or tested positive for SARS-CoV-2. NICE is then set to issue new evidence-based clinical guidelines in November about the support that Long Covid patients should receive. This will enable NHS doctors and other staff to provide clear, personalised treatment plans.
- An online rehabilitation service – ‘Your Covid Recovery’ – will provide personalised support to patients. The service, which was launched in July, gives people general information and advice about living with Long Covid. In Phase 2 of the project, patients will be able to access tailored rehabilitation plans.
- There will be designated Long Covid clinics where patients will be able to receive physical, cognitive, and psychological assessments and be referred to specialists when necessary.
- A team from the National Institute for Health Research will work with 10,000 Long Covid patients to better understand their condition and refine appropriate treatments.
- The NHS’s support services will be overseen by a new NHS England Long Covid task force, which will include Long Covid patients, medical specialists, and researchers.
Commenting about the issuing of new guidelines, the charity Patient Safety Learning said: “We welcome this measure and plans to update guidance so that it includes patients who may not have had a hospital admission or a previous positive test.
“We have heard from patients who have expressed their frustrations around the lack of clinical recognition of their illness, exacerbated by receiving a negative test result.”
The charity welcomed NHS England’s commitment to a one-stop approach to supporting Long Covid patients and said: “It is important that we recognise that patients may need to access a wide range of services and that patients who are unwell should not have to move between different clinical specialities to get diagnosis and treatment related to their personal needs.”
Patient Safety Learning said it appeared that the new measures would only be introduced in England. “We would be keen to clarify what steps are being put in place to support patients in the other three nations of the UK,” the charity said.
