Pediatric hospitalization for Covid-19 has soared during the summer as a very contagious Delta variant throughout the country, according to two new studies from controlling centers and prevention of disease.
From the end of June to mid-August, inpatient levels in the United States for children and adolescents increased almost five times, even though they remained slightly below the peak of January, one new study was found.
But vaccination has made a difference.
During this summer wave, the inpatient level is 10 times higher in adolescents who are not vaccinated as they are vaccinated, the researchers found.
Pediatric hospital receipts are almost four times higher in the state with the lowest level of vaccination such as the highest level, according to the second study.
The study, released on Friday, did not provide a clear answer about whether Delta caused a disease that was more severe in children than the previous virus version.
The rise of pediatric hospitalization can also be due to high infection variations.
Indeed, one study concluded that the proportion of children treated in hospitals with severe diseases has not changed at the end of June and July, when the Delta variant became dominant in the United States.
Rates reported in the CDC study are based on data from two national supervision systems, including hospitals in 49 states and Washington, DC.
In one CDC study, the researchers found that since July, the level of the new Coronavirus case increased for children 17 or younger, as well as the emergency room visit associated with Covid-19.
“We see that ER visits, cases and hospital admissions rose,” said Dr.
David Siegel, Lieutenant Commander in Public Health Services A.S.
and the main paper writer.
“It could be a more severe delta or delta more transmitting, and it can be related to other factors such as masking.” The study also found that the visit of an emergency room related to Covid-19 and hospitals among children more than three times higher in the state with the lowest vaccination coverage compared to the state with a high level of vaccination, underlining the importance of community vaccination for Protect children.
Other important factors that may affect regional differences including masking and social distance measures, research is recorded.
Last month, when Delta surged, the Covid-19 incident in children rose from the beginning of the summer – reaching 16.2 cases per 100,000 children aged 4 or below; 28.5 cases per 100,000 children aged 5 to 11; and 32.7 cases per 100,000 children aged 12 to 17.
The rate represents a sharp surge from June 1.7 per 100,000 children aged 4 years or below; 1.9 cases per 100,000 children aged 5 to 11; and 2.9 per 100,000 children aged between the ages of 12 and 17.
It was still under the incidence of the peak of cases among children last January.
The proportion of Covid-19 patients under 17 recognized for intensive care units ranged from 10% to 25% from August 2020 to June, and drifted at 20% in 2021, according to CDC research.
In the second study, researchers analyzed data from the Covid-Net supervision network, which included information about hospitalization in 99 states in 14 countries.
During the pandemic – or from March 1, 2020, until August 14, 2021 – there were 49.7 inpatients regarding Covid-19 per 100,000 children and adolescents, the researchers found.
But weekly rates have climbed since July.
During the week ended August 14, there was 1.4 in-related hospitalization for every 100,000 children, compared to 0.3 at the end of June and early July.
(It remains a little below the top weekly rate of 1.5 inpatient per 100,000 children, in early January 2021, in post-holiday wave cases.) Inpatient level has increased the sharpest for children aged 4 or younger.
On the week ended August 14, there were 1.9 inpatient per 100,000 children in that age group, almost 10 times more than in the end of June.
But based on the limited data available so far, there seems to be no Delta variant influences the incidence of severe disease or death among children, which is rather stable and relatively low in all pandemics.
Among the children and adolescents were hospitalized from June 20 to July 31, 23.2% were treated on the ICU, 9.8% mechanical ventilation needed and 1.8% died.
The numbers were roughly the same as those for children who were hospitalized before the Delta variant became widespread.
