There have been more than 1.6 million confirmed cases of coronavirus in the UK and nearly 60,000 people have died, government figures show.
However, these figures include only people who have died within 28 days of testing positive for coronavirus and other measures suggest the number of deaths is higher.
England's month-long lockdown ends on Wednesday, with a "three-tier system" due to return following a vote in the House of Commons on Tuesday evening.
All areas in the Eastern region were due to be in tier two - high alert, meaning people cannot socialise with other households indoors and the rule-of-six applies outdoors.
In Essex, the case rate in Basildon was the 16th highest in England in the week to 27 November and had risen week on week.
Essex County Council said the district was "a growing concern".
Data from the council suggested up to 40% of cases may be related to schools, but the authority said it did not know whether the infections occurred within school or the wider community.
The county council said testing kits will be offered to parents in neighbourhoods with the greatest number of cases to test their children.
Basildon Council's leader, Labour's Gavin Callaghan, has called for the district's schools to close from 11 December to curb infection rates.
Harlow has also seen its rate rise and it has the 55th highest case rate in England.
Thurrock, Castle Point and Epping Forest, where the rate has fallen, were all also above the England-wide average.
In Norfolk, all districts have seen rates fall, except Broadland and North Norfolk, which previously had one of the lowest in the country.
Ipswich continues to see a week-on-week rise in case rates, but all other districts in Suffolk continue to fall.
