As overall coronavirus infections decrease with the introduction of COVID-19 vaccines in recent weeks, children make up a larger share of new cases. However, hospitalization and infection rates for children are stable.Children accounted for only 2% of all new infections in March 2020. According to the American Academy of Pediatrics, children accounted for more than 24% of new weekly infections by May, even though they make up only 16% of the population.Experts say it is a sign that more people, both adults and teens, need to be vaccinated. This will prevent the virus from spreading to others and causing further illness.The virus can infect anyone at any age. Dr. Robert Frenck is a professor of pediatrics at Cincinnati Childrens Hospital and director of Center for Vaccine Research. He presented the data Wednesday at a Johns Hopkins University University of Washington symposium called Covid-19 and Children: Impacts. Uncertainties. and the Role of Vaccines.According to the AAP, more than 4 million children in America have been tested positive for COVID-19. 18,500 of these children were admitted to hospital and 336 died. About 4,000 children have been admitted to hospital with multisystem inflammatory disorder children (MIS-C), a rare but serious condition that the CDC has linked with COVID-19.Experts say that 55% of Americans had received at least one dose of vaccines as of Friday. However, vaccination rates in the United States are not uniform and can lead to outbreaks or childhood infections.Frenck stated that there are places where the vaccination rates are as low at 20%. Frenck said that it is not when, but when.Experts in health say it is crucial to boost vaccination rates, as the Delta variant continues spreading throughout the U.S.Continue the storyMayo fires Wisconsin doctor who wrote a book about COVID pandemic.If you have COVID-19 vaccinations, mask guidelines can be confusing. Experts explain the details.Although it is too early to determine if the Delta variant causes more severe illness in children, experts believe that the variant may be causing more symptoms than the original virus.Based on the data that we have so far, this variant is the most contagious. We expect to see more rapid transmission from children and adults to the virus.Scientists are intensifying their efforts to complete clinical trials in order for the Food and Drug Administration to approve the vaccine for younger children as quickly as possible.Moderna and Pfizer are working together with pediatric hospitals to combine Phase 2/3 trials. This will allow them to expedite the process in the summer and submit data by the fall.Versalovic stated that we expect to get emergency authorization for the COVID vaccines in the early part of next school year. This is still a priority, and the rapid spread of the Delta variant has made it even more urgent.Follow Adrianna Rodriguez @AdriannaUSATUSA TODAY's coverage of patient safety and health is possible in part thanks to a grant from Masimo Foundation for Ethics, Innovation and Competition in Healthcare.
