Studies have shown that children are faster to remove new coronavirus from their bodies

, Nov. 9 (Xinhua) -- The U.S. website
reported on the 8th that "research shows that the new coronavirus antibodies in children are weak." A new study
published in the British journal Nature Immunology shows that children infected with the new coronavirus produce weaker antibodies than adults and have fewer types of antibodies. This suggests that children remove the virus faster than adults.
previous studies have shown that an overly strong immune response may be the cause of critical illness and even death in some new corona patients. The weak immune response in children means that they have eliminated the new coronavirus before it has a chance to spread, which may help explain why children rarely develop severe illness. This may also explain why children are less likely to transmit the virus.
Researchers at Columbia University and others analyzed new coronavirus antibodies in four groups of patients: 19 adult donors who had recovered without being hospitalized, 13 adults hospitalized with acute respiratory distress syndrome due to the new coronavirus, 16 children hospitalized with multiple inflammatory syndrome, and 31 children without symptoms.
results showed that all groups of infected people produced antibodies. However, there are differences in the types of antibodies in children and adults. IgG antibodies that recognize the new coronavirus prickly protein are produced mainly in children. In contrast, adults produce a variety of antibodies to prickly proteins and other viral proteins, which are also more capable of suppressing viruses.
, who led the study, said: "Children have a lower protective response and a smaller range of antibody responses because children are not severely infected. In
two groups of children did not produce antibodies to the viral nucleoprotein. The nuclear crust protein is located around the virus genetic material, because it is inside the virus, not like the hedgehog protein is located on the surface of the virus, so the body's immune system only when the virus spreads in large numbers will find the nuclear crust protein, and produce corresponding antibodies.
these antibodies in children suggest that children have a shorter course of illness after infection, " explains Mr. Faber. The
may question the detection of antibodies to the nucleoprotein. Many of the antibody tests offered by some companies are specific to nuclear-shell protein antibodies, so children who have successfully removed the virus may be missed.
