With the onset of the return to normal life and the elimination of restrictions imposed during the Corona virus pandemic, increased attention is being paid to how children are affected by the virus, which raises many questions and concerns:
■ Do children face fewer risks than Covid-19?
■ ■ The US Centers for Disease Control and Prevention says the number of coronavirus-19 cases caused by coronavirus is lower among children than among adults. The center states that about 2% of confirmed cases of infection in the United States were owners under the age of eighteen, and this rate in China is 2.2%, in Italy 1.2%, and in Spain 0.8%.
But epidemiologists say that these rates do not likely include children who do not show symptoms of the disease as is the case for the general population, because checks are rarely performed for those who do not show symptoms.
■ Do children transmit infections like adults?
■ ■ A recent study observed a group of family infection foci at the international level with Covid-19, and found that children are the primary source of infection in less than 10% of cases.
The University of Queensland study report was published on the SSRN unpublished research platform in April and submitted to the Lancet medical journal for review by professionals.
■ Do children carry the virus to the same extent?
■ ■ At least one study of the amount of coronaviruses in the bodies of Covid-19 patients to measure what is known as “viral pregnancy” has found that the amount is not age-related.
Researchers at the Institute of Virology Science at the Charité University in Berlin said that an analysis conducted earlier this year for about 4000 positive samples concluded that the viral load is not much different in young people than in adults, which prompted them to warn against the expansion of the reopening of schools .
However, a separate analysis of that study conducted by the University of Zurich warned against the difficulty of interpreting the results because of the statistical methods used in it and the small number of cases that were identified in children and teenagers. "The reanalysis of the data summary with a trend determination test indicates that there is medium, if not overwhelming, evidence of an increased viral load with increasing age," wrote Dr. Leonard Heald, professor of biological statistics at the University of Zurich and head of the team conducting the analysis.
