The rate of genetic material of the coronavirus detected in the nose of children under five years of age is 10 to 100 times higher than that found in older children and adults, according to a us study published Thursday.

Very young children could therefore be significant propagators of the virus in the population, according to the study published in the medical journal JAMA Pediatrics, an assumption contrary to the current discourse.
The administration of Donald Trump pushes as well for weeks, and schools and child care centres of the different States to the reopening to revive the country’s economy.
Between 23 march and 27 April, researchers led Chicago screening tests with nasal swab on 145 patients, with a mild to moderate form of the disease COVID-19, a week after the onset of their first symptoms.
The patients were divided into three groups: 46 children under five years of age, 51 children aged 5 to 17 years) and 48 adults between 18 and 65 years of age.
The team observed the presence of SARS-CoV-2 in the amount of “10 to 100 times superior” to the other in the respiratory tract of young children.
The authors of the study have indicated that a laboratory study had shown that there were genetic material of the virus, the more this could become contagious.
“Therefore, young children can potentially be important factors of contagion of the SARS-CoV-2 in the population”, according to the scientists.
“The normal behavior of young children and confined areas in schools and day care centers raise the question of the spread of the SARS-CoV-2 in this population, as the health measures are relaxed,” they concluded.
These results do not go in the direction of what is stated in the health authorities, who believe that young children do not transmit many of the viruses, since it has been established that they have less risk of contracting a severe form of the disease.
However, little research has been done on this subject until now.
According to a study in South Korea, children aged 10 to 19 years of age to transmit the virus as much as the adults within a household, but children under nine years of age pass it on less.
