Islington Covid cases: Positivity rate explained

Data indicating a high COVID-19 PCR positivity rate in Islington is not a reliable measure of the virus's prevalence in the borough, according to Islington Council. While the UK Health Security Agency (UKHSA) reported a 58.3% PCR positivity rate for Islington on October 9, based on 31 tests yielding 18 positive results, the council has stated that low testing volumes mean such figures can fluctuate significantly and do not reflect the actual picture.

The UKHSA data for October 9 showed Islington with a positivity rate of 58.3%, compared to a London average that peaked at around 12% in early October and had fallen to below 8% by October 19. Neighbouring boroughs also reported higher rates, with Camden at 35% and Barnet at 27% in the same week. By the week ending October 12, Islington's PCR positivity rate had fallen to 39%, with 11 positive results from 28 tests.

Council statement on case numbers

Cllr Ruth Hayes, Islington Council's deputy leader and executive member for health, stated that just under 50 confirmed COVID-19 cases had occurred in the borough over the past month. She noted this number was similar to the cases confirmed during the same period last year. "We have seen a similar position in Islington, with an increase in reported cases over the last few weeks compared with the spring and summer," Cllr Hayes said, as reported by the Local Democracy Reporting Service. "We saw a similar pattern last year, with cases rising with the start of autumn."

Islington's Public Health department has encouraged residents to get any vaccinations they are eligible for and to practice good respiratory hygiene. This includes covering coughs and sneezes with a tissue or elbow, and regular hand washing with soap and water or using hand sanitiser.

National trends and booster uptake

The UKHSA has indicated that rising PCR positive rates and hospital admissions are part of a nationwide trend, not a localized issue. The agency reported on October 8 that positive tests and hospital admissions were increasing consistently across England, Scotland, Wales, and Northern Ireland, as well as in Europe and the United States. The UKHSA attributes this increase to factors such as colder weather leading to more time spent indoors, facilitating the spread of respiratory viruses, and potentially waning immunity from previous infections or vaccinations.

The UKHSA's surveillance report on October 22 showed that 34% of residents in England aged 75 and over had received an autumn booster jab. In comparison, 15% of individuals under 75 with weakened immune systems had received their booster. London has the highest ICU admission rate for COVID-19 in England, though the absolute level remains relatively low.
