A total of 1,366.8 infections per 100,000 people aged 10 to 19 were recorded in the seven days to October 17, up week-on-week from 1,134.9. The rate for five to nine-year-olds is 719.2, up week-on-week from 585.0.
For both age groups this is the highest weekly rate since data was first collected in October last year, says the UK Health Security Agency (HSA).
Pupils in England missed nearly 219million days of in-person education in the spring term due to Covid, figures show.
Historically, around five percent of school is missed due to absence in the spring term, but this year 57.5 percent of sessions (half a day) were recorded as missed due to coronavirus-linked reasons.
This represents almost 219million school days, according to the Department for Education (DfE) data.
For the majority of the spring term in England, students ‑ except children of key workers and vulnerable pupils ‑ were told to learn remotely until March 8.
A further 3.3 percent of sessions were missed during the spring term due to absence ‑ the equivalent of an additional 12.5million days on top of the 219million days where pupils did not attend due to Covid-19.
Vulnerable children, which included pupils who have an education, health and care (EHC) plan, could attend school in-person in the lockdown this year.
But the overall absence rate in special schools during the spring term was substantially higher at 25.5 percent, compared with around 10 percent historically.
