Some of the 35 million people infected with the virus will suffer from persistent effects.
COVID-19 patients who suffer from the mildest illness are at risk of suffering symptoms for months, French researchers have found.
Two-thirds of patients who had a mild to moderate case of Covid-19 reported symptoms 60 days after becoming ill, while more than a third felt still sick or in a worse condition than when their coronavirus infection took hold. start. Prolonged symptoms were more likely in patients aged 40 to 60 and in those who had to be hospitalized, according to staff at the Tours University Hospital, who followed 150 non-critical patients from March to June.
Their study, published Monday in the journal Clinical Microbiology and Infection, adds to the evidence that a proportion of the 35 million people known to have been infected with the SARS-CoV-2 virus worldwide will suffer from lingering effects for weeks or months later. Post-Covid clinics are opening in the wake of the pandemic to respond to a growing population of so-called long-haulers – survivors with scarred lungs, chronic heart damage, post-viral fatigue and other conditions persistent and debilitating.
“We were able to assess the course of the disease and demonstrate that even the mildest presentation was associated with mid-term symptoms requiring follow-up,” wrote Claudia Carvalho-Schneider and colleagues. “Thus, the Covid-19 pandemic will result in a burden of care long after its end.”
Two months after developing symptoms of Covid-19, 66% of adult patients reported suffering from at least one of 62 complaints, mainly loss of smell and taste, shortness of breath and fatigue, the researchers found. . The study aimed to identify the risk of a longer duration of symptoms in patients with non-critical Covid-19, as much of the existing international research was based on survivors admitted to intensive care units. they declared.
Longer-lasting studies and clinical trials will be essential to elucidate the durability and depth of the health consequences attributable to Covid-19 and how these may compare to other serious illnesses, Carlos del Rio, associate dean executive at Emory University School of Medicine, and colleagues wrote in an editorial in the Journal of the American Medical Association on Monday that reviewed the lingering effects of the coronavirus.
