The researchers also counted Covid-19 hospitalizations among children aged 12 to 17 from March 1, 2020 to April 24, 2021. The data comes from Covid-Net, a population-based surveillance system in 14 states, which accounts for about 10 percent of the Americans occupy. .

The number of teens hospitalized with Covid-19 declined in January and February this year, but rose again in March and April. From January 1, 2021 to March 31, 204 adolescents were likely to be admitted primarily to the hospital in Covid-19. Most children had at least one underlying medical condition, such as obesity, asthma, or a neurological disorder.
The rate may have increased in the spring due to the more contagious variants of the coronavirus in circulation, as well as reopening of the school that brought children together indoors, and the weakening of precautions such as wearing masks and taking social distances, say the researchers.
None of the children died, but about one-third were admitted to the intensive care unit and five percent needed invasive mechanical ventilation. About two-thirds of the surveyed teens were black or Hispanic, reflecting the greater risk to the population.
The researchers compared the numbers for Covid-19 with hospitalizations for influenza in the same age group during the influenza seasons 2017-18, 2018-19 and 2019-20. From October 1, 2020 to April 24, 2021, the hospitalization rates for Covid-19 among adolescents were 2.5 to 3 times the rate for seasonal flu in previous years.
The information is urgently needed to get more teenagers vaccinated, said Dr. Walensky said, adding that she was “deeply concerned” about the numbers.
The Food and Drug Administration approved the Pfizer-BioNTech coronavirus vaccine for children aged 12 to 15 years on May 12. The vaccine was approved for all parents in December.
