(*8*)Eight months after mild COVID-19, one in ten folks nonetheless has at the least one reasonable to extreme symptom that’s perceived as having a detrimental impression on their work, social or residence life. The commonest long-term signs are a lack of scent and style and fatigue. This is in keeping with a research printed in the journal JAMA, performed by researchers at Danderyd Hospital and Karolinska Institutet in Sweden.
Since spring 2020, researchers at Danderyd Hospital and Karolinska Institutet have performed the so-called COMMUNITY research, with the primary goal of inspecting immunity after COVID-19. In the primary part of the research in spring 2020, blood samples had been collected from 2,149 staff at Danderyd Hospital, of whom about 19 p.c had antibodies towards SARS-CoV-2. Blood samples have since then been collected each 4 months, and research individuals have responded to questionnaires relating to long-term signs and their impression on the standard of life.
In the third follow-up in January 2021, the analysis crew examined self-reported presence of long-term signs and their impression on work, social and residential life for individuals who had had mild COVID-19 at the least eight months earlier. This group consisted of 323 healthcare staff (83 p.c girls, median age 43 years) and was in contrast with 1,072 healthcare staff (86 p.c girls, median age 47 years) who didn’t have COVID-19 all through the research interval.
The outcomes present that 26 p.c of those that had COVID-19 beforehand, in comparison with 9 p.c in the management group, had at the least one reasonable to extreme symptom that lasted greater than two months and that 11 p.c, in comparison with 2 p.c in the management group, had a minimal of 1 symptom with detrimental impression on work, social or residence life that lasted at the least eight months. The commonest long-term signs had been lack of scent and style, fatigue, and respiratory issues.
“We investigated the presence of long-term symptoms after mild COVID-19 in a relatively young and healthy group of working individuals, and we found that the predominant long-term symptoms are loss of smell and taste. Fatigue and respiratory problems are also more common among participants who have had COVID-19 but do not occur to the same extent,” says Charlotte Thålin, specialist doctor, Ph.D. and lead researcher for the COMMUNITY research at Danderyd Hospital and Karolinska Institutet. “However, we do not see an increased prevalence of cognitive symptoms such as brain fatigue, memory and concentration problems or physical disorders such as muscle and joint pain, heart palpitations or long-term fever.”
“Despite the fact that the study participants had a mild COVID-19 infection, a relatively large proportion report long-term symptoms with an impact on quality of life. In light of this, we believe that young and healthy individuals, as well as other groups in society, should have great respect for the virus that seems to be able to significantly impair quality of life, even for a long time after the infection,” says Sebastian Havervall, deputy chief doctor at Danderyd Hospital and PhD scholar in the mission at Karolinska Institutet.
The COMMUNITY research will now proceed, with the subsequent follow-up going down in May when a big proportion of research individuals are anticipated to be vaccinated. In addition to monitoring immunity and the prevalence of re-infection, a number of tasks relating to post- COVID are deliberate.
“We will, among other things, be studying COVID-19-associated loss of smell and taste more closely, and investigate whether the immune system, including autoimmunity, plays a role in post-COVID,” says Charlotte Thålin.
