The coronavirus infection rate in Barnet has climbed to more than 100 cases per 100,000 people, analysis of the latest figures shows.

There were 421 laboratory-confirmed Covid-19 cases recorded in the borough during the week to October 9, giving a rate of 106 per 100,000 – up from 77.6 the previous week.

The data – based on figures from Public Health England published on the Government’s online coronavirus dashboard – is continually revised, meaning the figures are subject to slight variations. It means the previous week’s infection rate has been revised upwards from 70.

According to the latest statistics from online mapping system ArcGIS, the area of Barnet with the highest number of Covid-19 cases in the week to October 9 was Osidge, near the border with Enfield, with 17.

Hotspots include Edgware Park (16 cases), Friern Barnet (15), Golders Green North (15), Edgware East (14), Hampstead Garden Suburb (14) and Muswell Hill North (14).

Other areas with more than 10 cases were North Finchley, West Finchley, Whetstone East, Mill Hill Park, Copthall and Downage, Colindale, North Hendon and Sunny Hill, Totteridge and Barnet Gate, and Finchley Central.

The areas with the lowest numbers were Hadley Wood and Finchley Church End, which recorded between zero and two cases.

The figures for Barnet show a steady increase in the infection rate since the beginning of August, with particularly sharp rises since mid-September.

According to figures published by Barnet Council, the highest number of cases since July 1 has been recorded in those aged between 20 and 29. The second-highest number has been among those aged between 10 and 19.

Earlier this week, the Government announced a three-tier system of local lockdowns designed to curb the spread of the virus. Tier three represents the toughest restrictions, with indoor mixing between households banned and pubs and bars closed.

London has so far escaped tougher restrictions and remains at tier one, meaning existing measures such as the rule of six and the 10pm curfew continue to apply.

On Tuesday, Labour leader Sir Keir Starmer called for ministers to go further and bring in a so-called “circuit-breaker” lockdown across the whole of England, which could last up to three weeks, after it was revealed the measure had previously been recommended by the Government’s Scientific Advisory Group for Emergencies (Sage).
