COVID-19 Health & Wellbeing Board Briefing Southwark’s Outbreak Prevention & Control Plan Knowledge & Intelligence Team Southwark Public Health Division 9 June 2021
Cases have risen sharply across London, but bed occupancy and mortality remain stable KEY MESSAGES Cases are on the rise across London, with most boroughs experiencing significant increases in their incidence rates in the past week. Southwark had 186 confirmed cases of COVID-19 in the week up to 3 June. Across London, most boroughs now have rates above 25 per 100,000; eight boroughs including Southwark have rates above 50 per 100,000. The increasing spread of Variants of Concern (VOC) remain a risk in relation to transmission and immune escape. Across London, there continues to be steep increases of the B.1.617.2 variant (first identified in India). This is known as Delta variant. The number of NHS hospital inpatients with COVID-19 symptoms is still stable. Across the capital, around 250 hospital inpatients have confirmed COVID-19, with around 40 of these occupying mechanical ventilation beds. Coverage of the COVID-19 vaccine continues to increase across priority groups, and is comparable to similar boroughs such as Lambeth. Over 138,000 Southwark GP-registered patients have received their first dose vaccine. Almost 82,000 have received their second dose. Significant inequalities remain between ethnic minority groups, with coverage lowest among those from a Black Caribbean background. Geographically, coverage is lowest in Peckham and highest in Dulwich Village. Slide 2
Confirmed case numbers have risen sharply in the past week, both locally and across London CASES Cases are rising rapidly across London, with most boroughs experiencing significant increases in their incidence rates in the past week. Southwark’s 7-day incidence to 3 June stands at 58 per 100,000, more than doubling (130%) in the past week. This equates to 186 confirmed cases. London’s 7-day incidence stands at 44 per 100,000, increasing by more than half (57%) in the past week; and across London, 28 of the 32 boroughs now have rates above 25 per 100,000; with eight boroughs having rates above 50 per 100,000. Nationally, cases have increased by half (51%) in the past week, with England’s 7 day incidence rate now standing at 43 per 100,000, Figure 1: Weekly incidence rate per 100,000 population Figure 2: Weekly incidence rate per 100,000 population, since 1 April 1200 70 1000 60 58 50 800 44 40 600 43 30 400 20 200 10 0 0 01/04/2021 03/04/2021 05/04/2021 07/04/2021 09/04/2021 11/04/2021 13/04/2021 15/04/2021 17/04/2021 19/04/2021 21/04/2021 23/04/2021 25/04/2021 27/04/2021 29/04/2021 01/05/2021 03/05/2021 05/05/2021 07/05/2021 09/05/2021 11/05/2021 13/05/2021 15/05/2021 17/05/2021 19/05/2021 21/05/2021 23/05/2021 25/05/2021 27/05/2021 29/05/2021 31/05/2021 02/06/2021 01/07/2020 15/07/2020 29/07/2020 12/08/2020 26/08/2020 09/09/2020 23/09/2020 07/10/2020 21/10/2020 04/11/2020 18/11/2020 02/12/2020 16/12/2020 30/12/2020 13/01/2021 27/01/2021 10/02/2021 24/02/2021 10/03/2021 24/03/2021 07/04/2021 21/04/2021 05/05/2021 19/05/2021 Southwark England London Southwark England London References 1.

The overall case completion rate for Southwark remained high throughout May CONTACT TRACING NHS Test & Trace data enables monitoring of COVID-19 spread through the testing of suspected cases and tracing of recent close contacts. The overall case completion rate for Southwark is made up by the follow-up rates of the local and national teams, and the rates of case auto-completion of the online contact tracing form. Contact tracing figures are now being monitored on a monthly basis, due to the volatility of the weekly figures while referrals are very low. Average completion figures for national and local contact tracing throughout May: 85% of cases were completed; compared to 88% for London as a whole.

At our local trusts, the number of NHS hospital inpatients with COVID-19 is declining SECONDARY CARE Data on local hospitals’ confirmed COVID-19 admissions and inpatient diagnoses are provided by NHS situation reports. In the last week, combining new admissions and in-patient diagnoses, there have been: 5 cases at GSTT, and 11 cases at KCH-DH. There are currently 6 confirmed COVID-19 patients at GSTT, and 22 at KCH-DH. Across London, there are 247 patients in hospital with COVID-19, comparable to numbers last seen in late September. Of these patients, 41 are on mechanical ventilation beds in critical care.

PHE use two main classifications for new COVID variants; Variants of Concern and Variants Under Investigation COVID VARIANTS To date over 4,000 variants of SARS-CoV2 have been identified across the world. PHE continue to monitor the emergence of new variants and use two key classifications: Variant of Concern (VOC) Variant Under Investigation (VUI) An increase in transmissibility A variant with mutations in which we have A change in clinical presentation high confidence of significant change, but A decrease in effectiveness of public not yet meeting criteria of VOC health countermeasures Evidence of community transmission in the UK or abroad Alpha B.1.1.7 (UK): >240,000 confirmed Indian (B.1.617): 418 confirmed cases up cases to 3 June. Beta B.1351 (South Africa): >900 Insufficient data to confirm this is a VOC at confirmed cases this point, but remains under investigation Delta B.1.617.2 (India): >3,400 confirmed There are also a number of other VUI cases being reviewed Gamma P.1 (Brazil): 60 confirmed cases References 1.

Delta variant cases are now making up an increasing proportion of the cases seen across Southwark & London CASE NUMBERS AND RATES Delta variant case numbers have rapidly increased both locally and across London, and are making up an increasing proportion of total cases. In the week up to the 2 June, Delta variant numbers doubled in Southwark (103%), and increased by three-quarters (75%) in London, and by 84% across England as a whole. The time between when a case result is sequenced, and the presence of a variant is confirmed, can be a lag of up to 14 days. Therefore, the true proportion of cases made up by the Delta variant may be different than reported. In the week to 1 May, the Delta variant made up just 6% of all cases in Southwark; in comparison, Delta variant cases made up 40% of all cases in the week to 2 June.

Cases are rising sharply across London, with the R number now between 1.0 – 1.2 HORIZON SCANNING Indicators The alert level has been lowered to 3 “the virus is in general circulation”. ONS estimates that 1 in 580 people in London had COVID-19 in the week to 28 May. The national R number is currently 1.0–1.2, the same as London. This means the epidemic could either be flat, or growing slightly, though clusters of new variants mean it is becoming more difficult to interpret R estimates. Variant of Across London, there continues to be steep increases in confirmed cases of the Delta Variant of Concern (B.1.617.2), first identified in India. Public Health England estimate Concern transmission rates for the variant to be roughly two-thirds higher than for the Kent variant, and in many areas of the UK, this variant is replacing the Kent variant and dominating transmission. Separate analysis looking at household infections put the variant at around 50% more transmissible. Analysis by Public Health England has found both the Pfizer and AZ vaccines to be highly effective against symptomatic disease from the Delta variant after two doses. However, after just one dose, both vaccines were found to only be 34% effective against symptomatic disease from the variant. Key Latest ONS figures indicate that disparities similar to that observed in first dose vaccination rates were also seen in second dose vaccination rates. For example, less advantaged socio- Research economic groups were less likely than their counterparts to continue to a second dose; and people without English as their first language also had substantially lower rates of continuing to a second dose, compared to native speakers. COVID-19 Southwark has had 457 deaths related to COVID-19, with 3 deaths in the week up to 28 May. Overall, Southwark had 297 excess deaths in 2020, with an additional 107 Mortality excess deaths in 2021. Slide 10
