More than 15 areas of Northampton are seeing Covid-19 cases rise faster than the national average.
Latest figures show one ward reported enough positive tests in a week to give it an infection rate of nearly 600.
Data analysts divide the county into areas with roughly equal population — around 7,200 — to find comparisons on how coronavirus is spreading using figures for new positive tests and calculating the number assuming each 'Middle Layer Super Output Area' had a 100,000 people.
One area, New Duston West, recorded 30 lab-confirmed positive tests in the week to November 11 — six days into the four-week national lockdown.
That gave the area an infection rate of 567.9 per 100,000 — the highest in Northamptonshire.
Abington Vale and Kings Heath were other areas with infection rates over 300.
All those who test positive are told to self-isolate for ten days while close contacts identified by the Test and Trace service must stay at home for two weeks.
