With the emergence of novel coronavirus vaccine, this thought that the epidemic will be better, but did not think that the mutant novel coronavirus is coming again, the United States a newborn body detected a new variant of the virus.
According to foreign media reports, a new variant novel coronavirus was found in a newborn with severe COVID-19 received by Children’s National Medical Center in Washington, US, and its viral load was much higher than that of other patients.
Researchers said the new strain of the virus came from a severely ill newborn born in September last year at Children’s National Medical Center in Washington, the United States, after sequencing the virus genome of the sample recently discovered the new strain.
Astonishingly, the viral load of the sample was 51,418 times higher than the other samples.
It is unclear how high the risk of transmission of the new variant is, but other studies of the novel coronavirus variant in children have found eight additional cases of the variant in the mid-Atlantic region of the United States.
Roberta Debiasi, chief of the division of infectious diseases at Children’s National Medical Center in Washington, noted that the mutated virus has an entirely new structure of the spike protein, which may make it more infectious.
It is not clear whether the new mutation is related to the high viral load in newborn samples, but it is presumed that they are closely related.
Of course, this could also be a coincidence, so further study of the mutated virus is needed.
Children with CoviD-19 had a lower incidence of severe illness, and these younger children were less likely to be infected with novel coronavirus, according to the data.
At present, the mechanism of the effect of novel coronavirus on children and infants remains to be further studied.
But in the past five months, according to the American Academy of Pediatrics and the Association of Children’s Hospitals, there has been a “dramatic increase” in the number of children infected with novel coronavirus. Severe cases in children are rare but persist, and there are serious and long-term side effects, including brain damage.
