Long COVID symptoms are not common in the pediatric population, according to a Swiss study published in the Journal of the American Medical Association (JAMA) on July 15.
Long-distance COVID, also known as long-distance COVID or post-acute COVID-19, is a condition in which you experience ongoing or new symptoms more than four weeks after your first infection with the CCP (Chinese Communist Party) virus. COVID-19 (Coronavirus infection. This condition can occur in people with severe or mild COVID-19 disease, or after vaccination with the COVID-19 vaccine.
Chao Corona, Longitudinal cohort study, Six months after SARS-CoV-2 antibody or serology testing, “low prevalence of symptoms compatible with long COVID in a cohort of randomly selected children” was found in Switzerland.
“This study reports a distribution of symptoms compatible with long COVID at the population level. Severe SARS-CoV-2 infection was not captured because it is rare in children,” the authors said. Is writing. SARS-CoV-2 is the scientific name for the CCP virus.
Thousands of students aged 6 to 16 from 55 schools in the Zurich district volunteered to draw blood for serological testing in three stages from June 2020 to April 2021. The online survey lasted for more than 12 weeks from October 2020.
Switzerland remains open during last year’s pandemic, except from March 16th to May 10th, when the country was blocked to curb the first wave of increasing cases of the CCP virus. Did. Swiss authorities did not consider children the main cause of the virus and only took precautions such as hand hygiene, physical distance and wearing masks for children over the age of 12.
Of the 2,503 students with a median age of 11 and who underwent serological testing in October or November, only 1,355 were included in the study. Excluded from the study were 238 students who were negative for the antibody but later became positive, 292 who were not retested by March or April 2021, and did not provide information about their symptoms. It consisted of 618 people.
Next, the researchers compared students with a positive (seropositive) SARS-CoV-2 antibody test to those with a negative (seronegative) test.
Of the 109 seropositive children, 9% experienced at least one symptomatology for more than 4 weeks and 4% experienced at least one symptomatology for more than 12 weeks, whereas they were seronegative. It was 10% and 2% of 1,246 people, respectively.
Among seropositive children, fatigue, poor concentration, and the need for more sleep were “the most frequently reported symptoms lasting more than 12 weeks.” “Since October 2020, seropositive children have not reported hospitalization.”
Some of the limitations of this study are the small number of children tested positive for antibodies, parental reports of childhood symptoms, and the possibility of misclassification of some children with false seropositive results. “Sex” was included.
The results of previous studies were “mainly limited to selected populations without controls, so it is not possible to estimate general overall prevalence and burden. Child population.”
so Another study A researcher tracking the COVID-19 infection rate of students in grades 8-12 in East Saxony, Germany, posted as a preprint in May, included 1,560 students in March and April 2021. We conducted a survey in Germany. -19 in adolescence, to distinguish between infectious disease-related symptoms and pandemic-related symptoms. “
They found that “there are no statistical differences comparing reported symptoms” between 188 sero-positive and 1,365 sero-negative students, and the long COVID was “more than previously thought.” Uncommon, it emphasizes the effects of pandemic-related symptoms on well-being and mental health. ” “
Recent studies suggest that long COVIDs are rare on average for children, but there is still much to learn about the condition of the affected people. Currently, there is no clear clinical definition of long COVID in children, making it difficult for doctors to distinguish long COVID from other conditions and distinguishing who is most at risk.
According to the Centers for Disease Control and Prevention, Symptoms are generally reported Individuals with long COVID: dyspnea, malaise, brain fog, cough, worsening symptoms after physical or mental activity, chest or stomach pain, headache, palpitation, fever, mood swings, smells and taste Changes, sleep disorders, lightheadedness, mood swings, rashes, changes in the menstrual cycle, muscle and joint pain, diarrhea, or pins and needles.
