According to one study, eight months after mild COVID-19, one in ten experienced at least one moderate to severe symptom that could adversely affect work, society, or personal life. To do.

The study, published in the journal JAMA, found that the most common long-term symptoms were olfactory and taste loss, and malaise.

Researchers at the Danderyd Hospital and Karolinska Institute in Sweden have been conducting so-called community studies since last spring, with the main purpose of investigating immunity after COVID-19.

“A study of the presence of long-term symptoms after mild COVID-19 in a group of relatively young and healthy working individuals found that the main long-term symptoms were loss of odor and taste,” said Senior Researcher. Charlotte Tallinn says. For community studies at Danderyd Hospital and Karolinska Institute.

“Fatigue and respiratory problems are more common among participants who have been infected with COVID-19 but not to the same extent,” said Tallinn.

In the first phase of the study, blood samples were collected from 2,149 employees at Danderyd Hospital, of which about 19% had antibodies to SARS-CoV-2.

Researchers collected blood samples every four months, and study participants completed a questionnaire about long-term symptoms and their impact on quality of life.

In a third follow-up in January this year, the team reported the presence of self-reported long-term symptoms of participants who were infected with mild COVID-19 at least eight months ago, which affected work, society, and family life. I investigated the effect.

The group consisted of 323 health care workers (83% of women aged 43 years) and 1,072 health care workers, including 86% of women aged 47 years who did not have COVID-19 throughout the study period. Was compared with.

The results show that 26% of those who previously had COVID-19 had at least one moderate to severe symptom that lasted more than 2 months, compared to 9% of the control group. I will.

Approximately 11% had at least one symptom that adversely affected work, society, or family life, compared to 2% in the control group, according to researchers.

The most common long-term symptoms were loss of smell and taste, malaise, and respiratory problems.

However, researchers did not see an increase in the prevalence of cognitive symptoms such as brain fatigue, memory and concentration problems, muscle and joint pain, palpitation, and disability such as long-term fever. ..

Despite the fact that study participants had a mild COVID-19 infection, they said a relatively large proportion reported long-term symptoms affecting quality of life.

“In light of this, young and healthy individuals, and other groups of society, should pay great respect to viruses that may significantly impair their quality of life, even long after infection. We believe, says Sebastian Havervall, a PhD student in a project at the Karolinska Institute.

Researchers said community studies will continue and the next follow-up will take place in May, when the majority of study participants are expected to be vaccinated.
