New coronavirus may lie in children's nose 'more than 100 times more than adults'
A research result has been announced that 'up to 10-100 times more adult coronaviruses than adults' are present in the upper respiratory tract of children under the age of 5 with a novel coronavirus infection (COVID-19). The research team points out that children may play an important role in the spread of the COVID-19 epidemic.

Children Under 5 May Be Carrying Higher Levels of Coronavirus, New Study Suggests
The research team led by Taylor Heald Sargent, who belongs to the Department of Infectious Diseases at Ann & Robert H. Lurie Children's Hospital, has 145 subjects in a PCR test conducted by the hospital from March 23 to April 27, 2020. We conducted a survey to compare the amount of ' RNA of novel coronavirus' contained in the samples collected from the nose of. The subjects were 46 under 5 years old, 51 from 5 to 17 years old, and 48 from 18 to 65 years old. All samples analyzed were a week after the subject started to develop symptoms. It was collected within.
The analysis showed no difference in the amount of novel coronavirus RNA detected in samples of older children aged 5 to 17 years and adults 18 years of age or older, but from samples of children younger than 5 years. The RNA of the new coronavirus detected was 10 to 100 times higher than that of older children and adults.
According to the latest research result that ``the amount of new coronavirus RNA detected in the nose correlates with the infectivity of infected people'', the research team said that children under 5 years old will have a COVID-19 epidemic I pointed out that it may have contributed to. In addition, a research team at the Massachusetts General Hospital found that the new coronavirus was detected in the respiratory tract of 192 subjects aged 0 to 22 years, and the new coronavirus was more abundant than in adults infected in the intensive care unit. Much more has been announced on August 19, 2020, and attention is focused on the impact of the new coronavirus on children's epidemics.
On the other hand, research results that conflict with the results of this research have been reported so far. According to a South Korean study published in July 2020, teenagers had a similar chance of being infected with COVID-19 as adults, but children under the age of 10 were more likely to get COVID-19 than adults. The result is much lower.

Previous studies have shown that the younger you are, the less likely it is that COVID-19 will become more severe, and thus less likely to spread the virus. AFP, which reported this research, pointed out that 'there is almost no research of the same kind' and says that future research is awaited.
The World Health Organization (WHO) updated its Q&A on children and masks on August 21, 2020, saying, 'Children under the age of 5 do not need a mask. Ages 6 to 11 depend on the epidemic. Should wear masks like adults.”
