The proportion of infants hospitalized with Covid-19 in the UK has risen with the spread of Omicron, figures suggest, although the researchers urged calm, noting that most cases are very mild.
The number of Covid-positive admissions from any cause is expected to rise when there is more infection, but the latest figures suggest there has been a shift in the proportion of children hospitalized with a coronavirus who are infants.
Data from the Isaric/Co-CIN study, released by the Scientific Advisory Group for Emergencies (Sage) on Friday and based on a broadly representative subset of NHS hospitals, reveals that in previous waves of Covid around 30% of children hospitalized with the virus were under the age of one.
Between mid-December and mid-January, however, when Omicron spread rapidly across the country, the proportion was just over 42%, with children in the most deprived areas most affected. .
Calum Semple, professor of child health and outbreak medicine at the University of Liverpool, said infants usually had very mild symptoms.
