Lancet study found long-term covid symptoms in 46% of children after infection
London: Children infected with the SARS-CoV-2 virus can experience prolonged COVID symptoms lasting at least two months, according to a study published in The Lancet Child and Adolescent Health journal on Thursday (June 23, 2022). The largest study to date of prolonged COVID symptoms in children aged 0-14 years uses a national-level sample of children in Denmark and matches COVID-19 positive cases with a control group in which there is no evidence of illness. There is no prior history.
“The overall aim of our study was to determine long-lasting symptoms as well as quality of life and absence from school or day care in children and infants,” said Professor Selina Kikenborg Berg from Copenhagen University Hospital in Denmark.
“Our results show that, although positive COVID-19 diagnosis Children with PTSD are more likely to experience longer-lasting symptoms than children with a previous COVID-19 diagnosis, as the pandemic has affected every aspect of the lives of all young people,” Berg said.
The researcher said further research on the long-term consequences of the pandemic on all children would be important.
Long-term COVID in young people Most previous studies in the U.S. have focused on adolescents, with infants and children rarely represented.
In the study, the survey was sent to mothers or guardians of children between the ages of 0-14 who tested positive for COVID-19 between January 2020 and July 2021.
Overall, responses were received for nearly 11,000 children with positive COVID-19 test results, matched by age and gender, for more than 33,000 children who had never tested positive for COVID-19.
The survey asked participants about the 23 most common symptoms of chronic COVID in children and used the World Health Organization’s definition of chronic COVID as symptoms lasting more than two months.
The most commonly reported symptoms in children 0–3 years old were mood swings, rashes, and abdominal pain.
The most commonly reported symptoms at 4–11 years of age were mood swings, trouble remembering or concentrating, and rashes, and at 12–14 years of age, fatigue, mood swings, and trouble remembering or concentrating.
The results of the study found that children diagnosed with COVID-19 in all age groups were more likely to experience at least one symptom for two months or longer than the control group.
40 percent of children in the age group 0-3 years were diagnosed with COVID-19 (478 out of 1,194 children) for more than two months, compared to 27 percent of controls (1049 out of 3,855 children) Symptoms experienced.
For the age group 4–11 years, the proportion of cases was 38 percent (1,912 out of 5,023 children) compared to 34 percent of controls (6,189 out of 18,372 children), and for the age group of 12–14 years, it was 46 percent. . Cases (1,313 out of 2,857 children) experienced longer-lasting symptoms than 41 percent of controls (4,454 out of 10,789 children).
The types of non-specific symptoms associated with prolonged COVID are often experienced by otherwise healthy children; Headaches, mood swings, abdominal pain and fatigue are all symptoms of common illnesses that children experience that are not related to COVID-19.
However, the study showed that children with a positive COVID-19 diagnosis were more likely to experience long-lasting symptoms than children who never had a positive diagnosis, suggesting that these symptoms may last longer. Presentation of COVID.
This is supported by nearly a third of children with positive COVID-19 tests experiencing symptoms that were not present before SARS-CoV-2 infection, the researchers said.
Furthermore, with increasing duration of symptoms, the proportion of children with those symptoms decreased.
He said that generally, children diagnosed with COVID-19 reported fewer psychological and social problems than children in the control group.
According to the researchers, in the older age groups, cases often felt less fearful, had less trouble sleeping, and felt less worried about what would happen to them.
One possible explanation for this is increased epidemic awareness among older age groups, children in the control group fearing an unknown disease and having a more restricted everyday life due to protecting themselves from catching the virus, he said.
