The seven-day coronavirus infection rate in Barnet jumped by a third shortly before London was placed under Tier 3 restrictions.

The increase took the borough’s infection rate to 231.3 new cases per 100,000 people in the week to December 11.

It is the second successive week in which the infection rate has risen, following a short period of decline.

Despite the rise, the borough’s rate remains below those of neighbouring Enfield and Haringey, where they climbed to 424.4 and 279.7 new cases per 100,000 people respectively.

The latest infection rate data is based on figures from Public Health England published on the Government’s online coronavirus dashboard. It is subject to slight variations, as the figures are continually revised.

Friern Barnet saw the highest number of new cases in the week to December 10 at 47, according to a Government map of ‘middle layer super output areas’.

Colindale (45 cases), Brunswick Park (33), North Finchley (32) and Colney Hatch (32) also recorded relatively high case numbers.

Golders Green South (seven cases) and New Barnet Town and East Barnet (11) saw the lowest case numbers.

According to the latest information published by Barnet Council, most age groups are seeing an increase in Covid-19 cases, apart from those aged 10 to 19.

There are currently five outbreaks in care homes, with others reporting single cases.

In addition, around 5,000 pupils attending Barnet schools are self-isolating because of Covid-19 cases, according to the council’s latest weekly coronavirus report.

Health Secretary Matt Hancock announced on Monday that the capital would be placed in Tier 3 – the highest level of Covid restrictions – from Wednesday.

It means pubs, bars and restaurants will have to close their doors once again and can only offer takeaways, drive-throughs and deliveries. Shops can remain open but must follow guidelines to prevent the spread of infection.

Mixing between households is banned indoors and in private gardens unless they are in a support bubble. Groups of up to six people can meet in some outdoor public spaces, such as parks and public gardens.
