December 11th that many media mention that since the outbreak of the epidemic, children have accounted for only a small proportion of COVID-19 cases, and this trend has always puzzled scientists.
Now there is a growing amount of evidence to reveal why: children’s immune systems seem to be more capable of clearing the novel coronavirus than adults.
According to Melanie Nylan, an immunologist at the Murdoch Children’s Institute in Melbourne, Australia, the children’s immune system will produce a rapid and effective immune response when it finds the virus, and the virus has the opportunity to self-replicate so that the virus test results are positive. Before sex, remove these viruses.
Researchers at Columbia University published a report pointing to the current scientific evidence that children and adults produce different types and quantities of antibodies in response to COVID-19 infection.
The difference in antibodies indicates that the infection process and immune response of children are different, and most children are more likely to clear the virus from the body.
“The infection process in children is much shorter and likely not as broad as adults,” said Matteo Poloto, one of the authors of the study. He also said: “Children can eliminate the virus more effectively than adults, and it is likely that it does not require a strong antibody immune response.”
According to the report, one of the most prominent manifestations of the COVID-19 pandemic is that most children are better able to cope with the virus, while the elderly have to fight a fierce battle with the virus.
“This is a new virus for everyone, but children can respond to the pathogen in a unique adaptive way for the first time,” said Columbia University immunologist Donna Faber. This is unique to its immune system.
Children have many naive T cells that can recognize various new pathogens, while the elderly mainly rely on immune memory. Adults are far less able to respond to new pathogens than children.”
