Study shows Delta does not cause more severe childhood Covid – Naveen Bharat

WASHINGTON: US Pediatric Covid hospitalizations have increased since delta became prominent, but a new study that takes a first look at relevant data suggests that this type of fear leads to more severe disease.
by paper Centers for Disease Control and Prevention It also found that between June 20 and July 31, 2021, adolescents who were not vaccinated were 10 times more likely to be hospitalized than those who were vaccinated.
The health agency analyzed field hospital records, covering about 10 percent of the US population, between March 1, 2020 and August 14, 2021.
This covered the period before the emergence of Delta, the most infectious strain ever detected, and after it took effect, June 20.
Weekly hospitalizations for children aged 0-17 were the lowest at 0.3 per 100,000 between June 12 and July 3, rising to 1.4 per 100,000 in the week ending August 14 – a 4.7-fold increase.
Pediatric hospitalizations hit their all-time peak of 1.5 per 100,000 in the week leading up to January 9, when the US experienced its winter wave that was driven by Alpha type.
According to prior research, children in the age group of 12-17 and 0-4 have a higher risk of Covid hospitalization than children in the age group of 5-11 years.
After examining 3,116 hospital records from the pre-delta period and comparing them with 164 records during the delta period, the percentage of children with severe indicators was not found to differ significantly.
Specifically, the percentage of hospitalized patients admitted to intensive care was 26.5. Was pre-delta and 23.2 posts; The percentages placed on ventilators were 6.1 pre-delta and 9.8 post; And the percentage of those who died was 0.7 pre-delta and 1.8 post.
These differences did not rise to the level of statistical significance.
This finding comes with important caveats as the number of hospitalizations after the delta The shorter the period, the more data scientists will need to acquire to gain more confidence about the conclusions.
The study also outlined the vaccine’s effectiveness against pediatric COVID hospitalization during Delta.
Between June 20 and July 31, 68 adolescents were hospitalized with COVID-19 whose immunization status was known, 59 were not vaccinated, five were partially vaccinated, and four were was fully vaccinated.
This meant that people who were not vaccinated were 10.1 times more likely to be hospitalized than those who were not vaccinated.
a second study by CDC Screened childhood COVID cases, hospitalizations and emergency department visits from June to August 2021 and compared them with the level of community immunization at that time.
Compared to the states with the highest quartile, Covid-related pediatric (ages 0-17) emergency department visits and hospitalizations were 3.4 times higher and 3.7 times higher in the states, respectively, falling in the lower quartile of total vaccination per capita. Gaya.
The key message is that, while vaccines for under 12 years of age await clinical trials and subsequent authorizations, high community rates of vaccination prevent COVID transmission and protect children.
