　　New computational analysis shows that people under the age of 20 are more likely to be infected with COVID-19, half of which are adults, and less likely to be infected with other viruses. Israeli scientists have published their work in the journal PLoS Computional Biology. The results of these findings are shown. In the report. Previous studies have shown that children’s symptoms and the clinical course of COVID-19 are different compared to adults. Others report that the proportion of children diagnosed is lower than that of older children. However, few studies have compared infection patterns between age groups, and the conclusions are uncertain.

　　In order to better understand the susceptibility and transmission of children, the COVID-19 test result data set by Dattner and others in the densely populated Israeli city of Bnei Brak included mathematical and statistical models of household infections. I modified this. The data set covers 637 families whose members have been tested for active infection through PCR in the spring of 2020. Some people have also performed serological tests for SARS-CoV-2 antibodies. By adjusting the model parameters to fit the data, the researchers found that people under the age of 20 are 43% more sensitive than people over the age of 20. It is estimated that the infectivity is about 63% of adults, and children are unlikely to spread COVID-19 to others. The researchers also found that although children are actually infected, they are more likely to have negative PCR results than adults.
