Two years group have been sent home after a positive cases of coronavirus at St Michael's School.

Year 9 and Year 11 were told to study from home after the school on High Elms Lane announced to parents that some students and a member of staff tested positive.

The news was confirmed in a letter to parents on Tuesday (November 11) and head teacher Edward Conway suggested that the cases were related to a "significant increase" of coronavirus in the area.

In the letter, he said this has had an "adverse effect" on other schools including St Michael's and that other people are also having to self-isolate as well as the two year groups.

The letter read: "You will probably be aware that there has been a significant increase in coroanvirus cases in Watford over the past 10 days.

"This has had an adverse effect on numerous schools including St Michael's.

"As a result, we have had to ask Year 9 and 11 to study from home. This is due to some students and a member of staff testing positive and others having to self-isolate.

"We know that you may find this concerning but we are continuing to monitor the situation and are working closely with Public Health England."

Mr Conway also said that a number of students who have tested positive have only had mild symptoms such as the common cold.

As a result, he has asked parents to be cautious and if their child displays such symptoms then to keep them at home and get a test.

The letter continued: "If their test is negative they can return to school, providing nobody else in the family has tested positive.

"Please be assured that we're doing everything possible to keep everyone safe within the St Michael's community.

"The safety of students, staff and all of our families is of the upmost important and adherence to the measures outlined is essential in minimising the risk of transmission."
