A secondary school has decided to partially close after a pupil tested positive for the Covid-19 coronavirus.

In a letter sent to parents today (March 18), Kings Langley School confirmed that a Key Stage 3 pupil had contracted the virus. Key Stage 3 covers years 7 to 9.

The letter by headteacher David Fisher read: "Today like other schools, we have had our first confirmed case of the virus.

"We have a duty to inform you that you and your children may had inadvertently been in contact with someone who has coronavirus.

"We complete a deep clean of the school every day which obviously limits the spread of the virus and have consulted with Public Health England.

"We have a number of staff who fit into the newly defined vulnerable group including those who are pregnant, and other who we feel should not be working in school until told otherwise due to health complications."

As a result of the confirmed case, the school have informed parents that students in years 7, 8 and 9 must work from home this Thursday and Friday.

But students in Years 10, 11, 12 and 13 are expected to be on the site.

In the letter, the school explained it will inform parents this Friday on the school's position moving forward.

The school said it has been working closely with Hertfordshire County Council and Public Health England.

Staff who have partners or children who are not well have been advised to self-isolate.

The school will also no longer have parents or guests visiting the school, and after-school extra-curricular activities have been postponed.

The letter read: "We will do our best to set work for the classes through Show My Homework. As a school please be patient with staff, staff who are in school will most likely be covering for absent colleagues.

"I would also like you to know how proud I am of the way our students are conducting themselves and asking mature, sensible questions about the situation, whilst remaining engaged and focused on their studies."
