Scientists investigate post-Covid-19 fatigue cases | Society

Most people experience Covid-19 as a short-term disease – once the infection has been combated, they return to health. But evidence is emerging for a significant minority – sometimes referred to as “long haul carriers” – who struggle with long-term symptoms for a month or more.

Anecdotal relationships abound with people left with fatigue, muscle pain and difficulty concentrating. Online support groups have sprung up on Facebook and Slack, which already host thousands of members who claim they haven’t improved.

Speaking at the BBC’s Andrew Marr show on Sunday, Matt Hancock said it was difficult to gauge the extent of the problem. This is a really serious problem for a minority of people who crave, “said the health secretary.” Some people have long-term effects that look like post viral fatigue syndrome. “

Scientists are just beginning to study the potential causes of enduring fatigue, but they say there is likely to be a wide variety of reasons why some people face a longer road to recovery.

“Fatigue itself will take many different forms,” ​​said Chris Brightling, a professor of respiratory medicine at the University of Leicester, who is conducting a recently announced £ 8.4 million study on the long-term health impacts of Covid-19. .

A report published in February by the World Health Organization, based on preliminary data, suggested that, in mild cases, the median recovery time from Covid-19 is approximately two weeks from the onset of symptoms and three to six weeks for serious or critical cases. However, some of those who appear to have only mild illness initially also end up struggling with symptoms, including fatigue, that persist for weeks or months.


Those who have suffered from severe illness in the acute phase, including admission to intensive care, typically suffer from muscle loss, which can result in direct physical fatigue. Others remained with lung damage, including scarring that can cause wheezing, leaving people tired. There are other physical effects that are less clear – the disease is known to cause blood clots in the lungs and other parts of the body – and neurological symptoms ranging from stroke to mood disorders such as anxiety and depression.

“How common each of these things is is simply not good information,” said Brightling.

There is previous evidence linking chronic fatigue syndrome (CFS) to infectious outbreaks, including Epstein-Barr virus and Q fever. A study of people infected during the 2003 Sars epidemic revealed that almost a third had reduced exercise tolerance many months later, despite having normal lung function.

Brightling’s study will follow approximately 10,000 patients who have been hospitalized with Covid-19. This will allow scientists to evaluate what percentage of patients end up with what long-term health impacts and what are the risk factors for different symptoms. This could help pave the way for better treatments and medical support for those who have been in difficulty months after initially getting sick.

Understanding how Covid-19 triggers the symptoms of fatigue could also offer new insights into some of the ways in which chronic fatigue can occur more generally. “One of the big challenges is that there is so much we don’t understand yet,” said Brightling. “People who specialize in fatigue see people with multiple reasons why they ended up at that point.”

In this case, he said, since the trigger for fatigue is known, there is a better chance of understanding what is going on in the body. “It gives you a way to try to unravel that puzzle,” said Brightling.
