More than 50 students have been forced to self-isolate at a North Somerset school after one pupil tested positive for coronavirus.
A deep clean has been undertaken at Churchill Academy and Sixth Form after a student was diagnosed with the virus.
As a precautionary measure, 57 students, who are members of the same teaching bubble, will be in quarantine for 14 days.
Director of Public Health Matt Lenny at North Somerset Council said it was important people remembered the virus has not gone away over the summer.
He said: “We have been working closely with the school and Public Health England to ensure that effective infection control measures are in place and are confident that the school has acted promptly and efficiently to ensure no onward spread of infection.
“The identification of this case at the start of the new academic year should remind us all that the infection has not gone away over the summer.
“As the number of cases in North Somerset, like other parts of the country, begins to rise we all need to do our bit to halt the spread of the virus.
“Everyone, regardless of their age or state of health, must continue to practise good hand hygiene, maintain social distancing of 2m wherever possible and self-isolate and book a test if they experience any of the symptoms of the virus.”
A total of 17 new cases were confirmed in North Somerset on Tuesday, the biggest daily rise in two months.
Nationally, coronavirus cases have been confirmed at a total of 62 schools last week.
