Why some people suffer from persistent symptoms long after COVID-19 is one of the most difficult questions facing doctors and scientists about a pandemic. – If it were related to the severe course of COVID-19, it would be easier. But that’s not the case, because we know that people who have had the disease mildly have long struggles with complications, say Australian researchers.
- “Long COVID” is a term for a prolonged recovery after an infection
- It is estimated that the problem affects 10-30 percent. patients, although there are reports that more than half of patients do not fully recover for many months after infection
- Long-term discomfort is common in people who have had COVID-19 mildly
- Scientists are looking for answers to why the body reacts this way, and whether a vaccine can help

Most people with COVID-19 have common symptoms such as fever, cough, muscle aches, headaches, and recover within a week or two.

«Long COVID» – the most common symptoms
The most common symptoms of “long COVID” are fatigue, shortness of breath, chest pains, palpitations, headaches, “brain fog”, muscle aches and sleep disturbances. There are other symptoms as well, such as loss of sense of smell and taste, restlessness, depression and being unable to work.
The phenomenon is being watched by doctors and scientists from WEHI in Melbourne (Walter and Eliza Hall Institute), the oldest medical research center in Australia and the University of Melbourne. For now, it is difficult to pinpoint precisely how many people experience the long-term effects of the infection, but 34% in the Australian center. patients who stayed in the clinic after their illness experienced symptoms for as long as 45 weeks after diagnosis.
The World Health Organization (WHO) says it’s 10 percent. patients, a study from Great Britain says about 30 percent. patients. Many cases go unrecognized as “long COVID”, which affects statistics, but most of all can lead to misdiagnosis.

The question of “long COVID” has not yet been answered
«There seems to be an important discrepancy between the severity of the initial COVID-19 disease and the development of significant and persistent symptoms during recovery. Most of our patients are young people with mild disease »emphasize Australian doctors. “Long-term symptoms are likely to be related to the complex interaction of physical and mental processes that developed after sudden inflammation from infection.”
Among the theories that may answer the question of why some people grapple with “long COVID” is the notion that COVID-19 may be a consequence of a malfunction of the immune system. “It is also possible that in the bodies of people with” long COVID “there is a” virus reservoir “or remnants of virus fragments that the body has not dealt with. These tanks are not contagious, but they can consistently activate the immune system »- according to the observations of scientists.

Can the vaccine help with “long COVID”?
Some patients report that their symptoms improve significantly after receiving the COVID-19 vaccine. As Australian researchers say, it is possible that the vaccine is diverting the immune system back on track by directly activating certain immune cells, such as T cells, which help stimulate antibody production and kill virus-infected cells, or the first-line innate immune cells that correct it malfunction of the immune system.
