In one study, it has been discovered that one in ten people experience at least one moderate to severe symptom that has a negative impact on their work, social or personal life.
The study, published in the Journal of the American Medical Association, found that the most common long-term symptoms are loss of smell and taste and fatigue.
Researchers at Sweden’s Dandrid Hospital and Karolinska Institute have been conducting so-called communication studies since the spring of last year, with the main aim to investigate immunity after COVID-19.
“We investigated the presence of long-term symptoms after mild COVID-19 in a relatively young and healthy working group, and we found that the major long-term symptoms are loss of smell and taste,” Charlotte Terryn The principal researcher for community studies at said Dandried Hospital and Karolinska Institute.
“Fatigue and respiratory problems are more common in participants who have COVID-19, but not to the same extent,” Thalin said.
In the first phase of the study, blood samples were collected from 2,149 employees at Dandrid’s Hospital, about 19 percent of whom had antibodies against SARS-CoV-2.
Researchers collected blood samples every four months, and study participants responded to questionnaires about long-term symptoms and their effect on quality of life.
He said that the most common long-term symptoms were loss of smell and taste, fatigue and respiratory problems.
