China News Service, August 2, According to Singapore's Lianhe Zaobao, researchers recently discovered that the genetic mass of the new coronavirus gene in the nasal cavity of young children under 5 years old is 10 to 100 times that of adults and older children, which means that young children may be the main "driver" of the virus's spread in the community.
In Spain, a little girl is in her online class time.
This study was reportedly published in JAMA Pediatrics. Between March 23 and April 27, researchers took a nasal swab test on 145 patients with mild to moderate disease in Chicago within a week of their symptoms. The patients were divided into three groups: 46 children under 5 years old, 51 children and adolescents aged 5 to 17 years old, and 48 adults aged 18 to 65 years old.
A research team led by Angluri Children's Hospital doctor Sargent observed that "the genetic material of the new coronavirus in the upper respiratory tract of young children is 10 to 100 times that of adults or older children."
The authors added that a recent laboratory study showed that the more viral genetic material appears in a patient, the more infectious viruses will multiply.
Previous studies also showed that if the amount of respiratory fusion virus (RSV) in young children is very high, it is more likely to be transmitted.
Research Group pointed out in this regard: "So, young children may be an important driving force for the spread of the new coronavirus in the population." They believe that "the behavioral habits of young children, coupled with the confined spaces in schools or nurseries, are worrying about the spread of the new coronavirus in the middle of this group."
However, the conclusions of the research group are contrary to the views of the health authorities. It is generally believed that young children have a lower probability of severe illness and are less likely to spread the virus than adults.
