The return of students to Cambridge has helped fuel a rise in coronavirus cases in the city which last week had the highest infection rate of any area in the Anglia region.
Mass testing of students with or without symptoms is uncovering a relatively large number of cases with more than 130 cases per 100,000 and local health officials says that helps keep track of the illness.
Cases are continuing to rise across the Anglia region with infection rates also particularly high in Luton and Northampton.
The three areas has cases above 120 per 100,000 population in the latest weekly figures from Public Health England which cover the seven days to Friday 16 October.
Northamptonshire has the highest rate of coronavirus cases in the Anglia region with 101.2 per 100,000 across the county. Northampton had 126.9 cases per 100,000 with Wellingborough on 109.1. Health authorities in the area fear the county is on a 'tipping point' which could see a move from Tier 1 (medium) to Tier 2 (high) Covid restrictions.
The Essex County Council area is currently the only part of the Anglia region under Tier 2 measures
