The World Health Organization (WHO) has developed a definition of the so-called “long-term coronavirus”, which has been seen in some patients who have contracted coronavirus and “recovered” from COVID-19 but still suffer from many post-viral illnesses. According to specialists, this problem is more common in people who need hospitalization, but it also affects those who have had a mild illness. It usually manifests as fatigue, shortness of breath and cognitive impairment. However, experts note that not everything is recognized yet, and the definition that is currently being developed may change.
Physicians have been aware of the long-term complications of bocoid in some patients for a long time. Guidelines for its medical services were already developed in September by the British NHS – the equivalent of the Polish National Health Fund. Dozens or even hundreds of symptoms have been identified in research and trials.
“Long Covid” – WHO definition. What is long covid disease, what are the symptoms, who is it, how long does it last
Currently, its own definition has been prepared by the World Health Organization (WHO). According to her, we are talking about “Covid-19” when at least one disease is detected within three months of the discovery of SARS-CoV-2 infection or suspicion of infection with this infection. It must last for at least 2 months and cannot be explained by any other disease. Symptoms may appear during the acute form of COVID-19, and then persist, but they are also felt for the first time after recovery.
“Long covid” is often manifested by fatigue, shortness of breath and cognitive impairment. However, there may also be chest pain, changes in taste and smell, muscle weakness, and heart palpitations. It is noted that this disease often impedes daily functioning.
However, experts from the World Health Organization have expressed reservations that the definition has been developed on the basis of previous observations and may change.
Long Covid. Scientists Research
A large study by University College London (UCL) identified 200 symptoms affecting 10 organs or organ systems. According to the research 270,000 patients performed by specialists from Oxford University37 percent of those infected with COVID-19 have at least one symptom. This is more common in patients who have required hospitalization due to the severe course of the disease. However, COVID-19 can also occur in those who have had the disease in a milder form. According to Harvard University researchers who followed 50,000 patients, it’s more common in younger, middle-aged people under the age of 65.
Lung problems are a common problem after infection with COVID-19. According to a Chinese study, the results of which were published by The Lancet, 12 months after leaving the hospital, 20-30% of moderately ill patients and 54% of seriously ill patients suffer from it.
In people with coronavirus, chronic diseases such as diabetes and neurological disorders are often first detected. This is indicated by the observations of specialists from Harvard University.
Most symptoms of the long-term coronavirus go away after some time, no matter how severe the infection. WHO experts, however, warn that some diseases may re-emerge in some people.
According to preliminary studies, bucovidic symptoms can be relieved by the SARS-CoV-2 vaccine. However, the US Centers for Disease Control and Prevention (CDC) reserves that longer observations are necessary on this matter.
