Rise in Covid-19 cases among Borehamwood teens attributed to 'friendship groups' of Jews

The warning followed last week’s confirmation by Yavneh College head Spencer Lewis that some of his pupils were self-isolating.

"There are some Yavneh College pupils who currently need to isolate and who will not be able to start school on time next week," he said. "Most of these pupils were in direct contact with the few who have tested positive and all, I am pleased to say, have only mild symptoms.”

Hertsmere Borough Council leaders Councillor Morris Bright said: "The last thing any of us want to see is the spread of coronavirus in our community.

"We have to continue to act to prevent this current increase in the number of cases in the borough from spiralling further upwards. We do not want more deaths and untold woe for sufferers and their families.

"Wear a face covering; keep your distance; wash your hands more frequently and for longer; and if you are showing symptoms or have been in contact with someone who has tested positive for Covid-19, you must self-isolate for 14 days.

"Thank you to all those who are helping to ram home that message in our town centres and high streets.

"Let's work together to contain this threat and keep our community safe and well."
