A new U.S. study suggests that children who are younger than five and are infected with the COVID-19 Omicron variant have less risk of severe health outcomes than kids infected with the Delta variant.
Researchers analyzed the electronic health records of more than 651,640 children in the United States who had a "medical encounter with health-care organizations" between September 2021 and January 2022. According to the study, this included more than 22,772 children infected with Omicron in late December and late January, as well as more than 66,000 children infected with the Delta variant in the fall.
According to the study, the Omicron variant is six to eight times more infectious than the Delta variant. However, in children under the age of five, less than two per cent of children infected with Omicron were hospitalized, compared to 3.3 per cent of children with Delta. "We saw the number of hospitalizations within this age group skyrocket in January of this year because the infection rate of Omicron is about 10 to 15 times compared to that of the Delta variant," said CWRU professor Rong Xu in the release.
