A secondary school year group has been sent home to isolate after a number of Covid cases were confirmed.
Dartford Science and Technology College in Health Lane has told its year 10 pupils to work from home for the rest of the week.
It comes after the school confirmed three members of its school community had tested positive for the virus.
In a letter sent to parents it said: "We know you may find this concerning but we are continuing to monitor the situation and are working closely with Public Health England.
"This letter is to inform you of the current situation and provide advice on how to support your child. Please be reassured that for most people, Coronavirus will be a mild illness."
The Easter break starts tomorrow and ends on Friday April 16.
But pupils at the foundation school for girls with mixed sixth form entry are understood to be expected back a day early to catch up on school work missed following the disruption.
Principal Anne Davis said: "Year 10 are working from home for the remainder of this week due to a number of Covid cases within the year group.
"All students return to school for the summer term from April 15."
The school remains open for other year groups and says children should attend as normal if they remain well.
Analysis of Covid data by KentOnline shows while cases have crept up since the mass return of schools figure are still lower than they were before children went back.
So far the only other secondary school to have reported sending children home after a positive test result was Wilmington Academy, also in Dartford. A primary school in Minister had also sent year groups home.
