COVID-19 Suffolk Weekly Briefing

18 November 2020

Summary

  • 4 week national restrictions in England will be in place from 5 November until 2 December; during this period the national alert levels have been suspended.

  • In the 7 days up to 17 November, there have been a net 340 new cases of COVID-19 in Suffolk. This is a decrease on the numbers in the previous week HOWEVER please note that some of this decrease is due to the reallocation by Public Health England of historic Suffolk cases to other areas of England. This change has made the reporting of cases in students more accurate overall, but has artificially depressed figures in Suffolk in the current week.
  • The underlying rate of new weekly cases in Suffolk has risen slightly and is now, at 89.45 cases per 100,000 people. This is below the rates for the East of England region (154.33/ 100,000) and for England as a whole (274.25 / 100,000).
  • In total, up to the 6 November, there have been 582 deaths in Suffolk where COVID-19 was recorded on the death certificate. There have been 6 COVID-19 related deaths in the last 7 days.
  • The estimated ‘R’ value for the East of England is between 1.1 and 1.4 which has decreased in the last week, but remains higher than the ‘R’ value for England (1.1 – 1.2).

National alert levels

On 12 October a new three-tier system was introduced, which categorises areas as Medium Risk, High Risk or Very High Risk. All areas of Suffolk are designated Medium Risk as of 14 of October.
The three-tier national alert system is suspended during the period of national restrictions in England and will be reinstated when the national restrictions end.

Weekly cases and rates

COVID-19 cases are identified by taking specimens from people and sending them to laboratories around the UK to be tested. If the test is positive this is referred to as a lab-confirmed case.

In the week 11 November – 17 November (inclusive) there were 340 net new lab-confirmed cases of COVID-19 in Suffolk. This is a decrease on the previous week but this decrease is largely due to changes in the geographical allocation of cases by Public Health England.

It is possible to calculate a case rate by dividing the number of cases by the number of people in a given population – this makes it possible to compare cases across different areas. The most recent underlying weekly case rate in Suffolk was 89.45 cases per 100,000 people. This case rate has risen slightly since the previous week although Suffolk’s rate remains the lowest weekly COVID-19 case rate in the East of England.

Case numbers for the Districts and Boroughs in Suffolk are not being reported this week due to the data changes made by Public Health England.

Total cases and rates

As of 17 November there have been 6,300 total lab-confirmed cases of COVID-19 in Suffolk. In total there have been 828 cases of COVID-19 per 100,000 people. This is the lowest overall COVID-19 case rate in the East of England.

Regional ‘R’ Number and growth rate

What is the R number? R represents the average number of onward infections that will be generated by a single infectious individual. R tells us if the epidemic is getting bigger (>1) or smaller (<1) but now how large the epidemic is overall, and therefore shouldn’t be used as the sole indicator of the threat posed by an epidemic at any single point in time. R cannot be measured directly, and there is always uncertainty about its exact value.

The current estimated regional 'R' numbers are below - the East of England currently has one of the higher rates in England.

Death Registrations to 6 November 2020

In Suffolk, there have been 582 deaths which mention COVID-19 in total. There have been 6 COVID-19 deaths in the most recent week of data. Currently deaths due to causes other than COVID-19 are occurring at similar levels compared to the five year average for Suffolk.

Contact Tracing

The majority of contact tracing as part of test and trace in Suffolk is being done by Public Health England and the NHS Test and Trace Service, with the Suffolk Public Health team involved in some more complex cases. In the data as of 16November, 81.7% of all Suffolk cases had completed the test and trace process, the same as the England average of 81.7%. 61.8% of Suffolk contacts of cases have completed the NHS test and trace process, with the overall percentage of contacts completing the test and trace process rising to 73.0% once the contacts managed by PHE and locally are included. This is currently higher than the England average of 63.9%.
