A recent study of how COVID-19 appears in schoolchildren shows that children do not play a major role in the spread of the virus, according to Bloomberg Report.
Since mysterious inflammatory syndrome first appeared in children infected with SARS-CoV-2, researchers around the world, but especially in the USA and Europe (where the syndrome was most widely detected), worked on determining the nature of the relationship between this syndrome and the virus,
Of course, there is an important economic factor here: before you can expect that adults will return to work en masse, it is necessary to provide conditions for schoolchildren, since caring for children is prohibitively expensive for most families. Many colleges in the United States decided to resume classroom instruction in the fall, even if students followed the new guidelines regarding sensitivity to COVID-19. And while most expect elementary, middle, and high school students to return to class, most states have yet to make a formal decision.
Scientists from the Pasteur Institute, a large French research institute named after the scientist who invented the process of pasteurization of milk, studied 1,340 people in Crepe-en-Valois, a city northeast of Paris, where an outbreak occurred in February and March. The study involved 510 students from six elementary schools.
Among these students, researchers found three students who became infected with the virus. But in each example, it seems that the children did not transmit the virus to their parents or teachers.
Scientists from the Pasteur Institute studied 1,340 people in Crepe-en-Valois, a city northeast of Paris, where an outbreak occurred in February and March, including 510 students from six elementary schools. They found three likely cases among children that did not result in more infections among other students or teachers.
The study confirms that children appear to have fewer symptoms than adults and are less contagious, suggesting the reopening of schools in countries from Denmark to Switzerland. Researchers found that 61% of parents of infected children had coronavirus, compared with approximately 7% of parents of healthy children, suggesting that it was the parents who infected their children, and not vice versa.
This small study is one of several that suggest that young children do not often spread coronavirus. Although there was at least one study showing the opposite.
But because of this small number of students, scientists believe that they should study in more schools, like this one. However, it still seems that 41% of children infected with the virus did not have any symptoms …
Understanding the pandemic and the new patterns of transmission of the virus is key to determining which parts of society can be reopened – or should be reopened if revived – and mitigate the impact of the outbreak on the economy. Until now, data on children have been contradictory: some reports support Pasteur’s findings, and at least one of them points to the opposite.
Epidemiologist Arno Fontanet and his colleagues said that more research is needed in schools due to the small number of cases that they were able to study. They found that approximately 41% of infected children had no symptoms, compared with approximately 10% of adults.
… for adults it’s only 10%.
