More than 2/3 of London Covid cases are now Delta variant


ore than two thirds of Covid-19 cases in London are now believed to be the Delta variant, first identified in India, The Standard understands.

Latest weekly figures show that in the capital up to May 31 there had been 1,526 cases of the B1.617.2 variant detected– 247 of them individuals who had travelled into the UK.

The total was up from 991 for the previous week.

Hillingdon has had the highest number of cases, 148, according to data up to June 2, followed by Croydon on 137, Hounslow 118, Ealing 113, Brent 108 and Greenwich 100.

However, these figures are around two weeks out-of-date as it takes this length of time for genomic sequencing to identify variants.

So given that the Delta B1.617.2 variant is now dominant in London, a truer picture of the Covid and mutation situation is revealed by the figures for all cases.

The three boroughs with the highest seven-day rates per 100,000 people in the week to May 29 were:

  • Kingston at 81.1, with 144 confirmed infections in that week, up 74 (105.7%) on the previous week.
  • Lambeth at 55.2, with 180 cases, up 31 (20.8%)
  • Hounslow on 55.2, with 150 cases, up six (4.2%)

Professor Kevin Fenton, London Regional Director for Public Health England, said: “We are continuing to see gradual increases in cases across London, including of the Delta variant.

“Despite these increases, the number of people being admitted to hospital remains stable.

He also explained: “To prevent the spread, we are continuously reviewing our targeted response in areas where variants have been identified, including surge testing, enhanced contact tracing and increasing vaccine availability.

“Everyone must play their part.

“Be on the lookout for the tell-tale symptoms of coronavirus infection and get tested as soon as possible if you or close contacts feel unwell. If you are in contact with others, get tested regularly, whether you have symptoms or not. Free, quicker easy to use lateral flow tests are now available for everyone to check for infection.

“Vaccines remain your best and most effective protection against hospitalisation and death from the coronavirus, so please take up both doses of the vaccine when offered, encouraging friends and family to do the same.”
