Over 70% of children in United States are infected with COVID-19 Omicron

Over 70% of children in United States are infected with COVID-19 Omicron. 

Nature concerns: Omicron spreads rapidly among children, and over 70% of children in United States are infected. 

 

A newly published preprint paper shows that more than two-thirds of American children have been infected with the COVID-19 virus through antibody testing, and the COVID-19 infection rate among American children has doubled during the Omicron epidemic .

In the U.S., more than two-thirds of children ages 1-4 have contracted the virus, according to an analysis of the national survey.

During the Omicron epidemic, the 1-4 year old age group experienced a greater increase in infection than any other age group, also demonstrating the high transmissibility of the Omicron variant.

 

The study tested the COVID-19 antibody in the blood samples of more than 86,000 children under the age of 18 nationwide, and analyzed the COVID-19 infection of children, including about 6,100 children aged 1-4 years old.

The testing analysis showed that between December 2021 and February 2022, during the Omicron epidemic , the infection rate among young children aged 1-4 more than doubled, from 33% to 68%.

 

Overall, this large-scale testing analysis showed that most children aged 1-17 had been infected with the new coronavirus before February this year, with the highest infection rate among children aged 5-11, reaching 77%, and the overall infection rate of children. rate has surpassed that of adults.

This finding is important, especially for low- and middle-income countries where adult vaccination rates are low and children are not vaccinated for a short period of time.

Immunity from infection with the new coronavirus may help prevent future infections and possible severe illness in children.

But it also reminds us that the COVID-19 pandemic may not end until children around the world have also received enough COVID-19 vaccines.

 

Previously, the United States reported COVID-19 data showing that about 17% of children under the age of 18 were infected with the COVID-19 virus.

 

But the latest study, led by CDC epidemiologist Dr. Kristie Clarke , said this data is just the tip of the iceberg.

Because the number of cases reported based on PCR and antigen testing grossly underestimates the true infection rate, especially in children.

Because children infected with the COVID-19 are mostly asymptomatic or mildly symptomatic, many of them are not tested after they are infected.

 

To assess true Covid-19 infection in children, Dr. Kristie Clarke and her colleagues looked for the presence of anti-coronavirus antibodies in blood samples taken between September 2021 and February 2022. They tested anti-nucleocapsid protein antibodies.

Nucleocapsid protein (N protein) is the protein with the highest content and conservation in the new coronavirus, and the COVID-19 vaccine vaccinated in the United States does not exist or express this protein, so it can be Differentiate the detected antibodies not due to vaccination.

 

The high infection rate among children is also reflected in the hospitalization data. During the Omicron epidemic, the number of children under the age of 5 who were hospitalized due to COVID-19 infections was five times higher than during the Delta epidemic, and 3.5 times the number of children admitted to intensive care.

 

Dr Kristie Clarke believes there are various reasons for this, such as low Covid-19 vaccination rates among children, children under the age of 5 are not eligible for Covid-19 vaccines; and young children are also less likely to wear masks and maintain social distancing.

 

But don’t worry too much, a study recently published in the journal JAMA Pediatrics surveyed more than 650,000 American children under the age of 5 and found that the rate of severe illness during Omicron was only one-third of that during the Delta epidemic, so far So far, the hospitalization rate of children infected with the COVID-19 is much lower than that of adults, especially the elderly.
