The number of children hospitalized with COVID-19 in the US has increased since the Delta variant became common, but a new study by the US Centers for Disease Control and Prevention (CDC) has raised concerns. This variant causing severe illness in children is unfounded.

The document also shows that vaccines help reduce the number of children hospitalized with COVID-19.

CDC analyzed hospital data in an area with 10% of the US population for the period 1-3-2020 to August 14, 2021, from before the appearance of the Delta variant until this super infectious variant became the main cause of disease in the US from June 20.

The rate of children aged 0-17 who were hospitalized weekly was at the lowest level between June 12 and July 3 at 0.3 per 100,000 children, then increased to 1.4 per 100,000 in the period from June 12 to July 3. week ending August 14, that is, an increase of 4.7 times.

The peak of this rate was 1.5/100,000, recorded in the week to January 9, when the US witnessed a winter wave of infections caused by the Alpha variant.

After reviewing the data of 3,116 hospitals before the Delta variant appeared and comparing it with the data of 164 hospitals during the period when this variant was prevalent, the proportion of children with severe disease did not differ much.

In particular, the rate of severe hospitalization was 26.5 before the appearance of Delta and 23.2 after the appearance of this variant. The rate of needing a ventilator was 6.1 before Delta appeared, then 9.8. While the infant mortality rate was 0.7 before and 1.8 after the appearance of Delta.

However, the researchers also caution that because the number of patients admitted to hospital after the occurrence of the Delta variant is low, more data is needed to make this conclusion more certain.

The study also highlights the vaccine’s effectiveness in preventing children from being hospitalized with Delta variant infections. During the period from June 20 to July 31, out of 68 children admitted to the hospital, 59 children have not been vaccinated, 5 children have received one dose and 4 children have received two injections. Thus, unvaccinated children are 10.1 times more likely to be hospitalized than vaccinated children.

On September 3, President Joe Biden announced that next week he would announce the next steps in the fight against the Delta variant, and said the recovery process of the world’s largest economy is taking place quickly. sustainable and powerful way.

Meanwhile, the daily newspaper New York Times On the same day it was reported that top US health officials said they do not have enough data to recommend a booster shot at a more widespread level by the end of September as President Biden previously mentioned.
