The main points from this week’s national influenza and COVID-19 surveillance report are:

Surveillance indicators suggest that at a national level COVID-19 activity decreased in week 14 of 2021.

Case rates have fallen across all age groups.

Case rates continue to be highest in those aged 10 to 19, with a case rate of 42.8 per 100,000 population.

The lowest case rates continue to be in those aged 70 to 79, with a rate of 7.5 per 100,000 population.

Case rates per 100,000 have fallen across all regions and remain highest in Yorkshire and the Humber, at 57.4.

Case rates per 100,000 are lowest in the South West, with a rate of 12.8.

The number of acute respiratory infection incidents (suspected outbreaks) in England was 92 in week 14, compared to 140 in the previous week.

Seroprevalence data indicates that around 53.7% of the population have antibodies to SARS-CoV-2 from either infection or vaccination, compared to 15% from infection alone.

In the 70 to 84 years age group, around 97.7% had antibodies from either infection or vaccination compared to 4.8% from infection alone.

The hospital admission rate for COVID-19 has fallen – it was 1.85 per 100,000 in week 14, compared to 2.11 per 100,000 in the previous week.

Hospital admission rates for COVID-19 are highest in Yorkshire and the Humber, with a rate of 3.36.

The highest hospital admission rates continue to be those aged 85 and above.

Dr Yvonne Doyle, Medical Director at Public Health England said:

“Our efforts over many months have helped to suppress the virus, but I want to stress how even more vital it is to follow guidance as we go back to doing the things we have missed for so long. Many countries, including those on our doorstep, are facing another dangerous wave. Following guidance continues to be a matter of high protection for us all.

About half of us do not yet have protective antibodies from either recent infection or vaccination, so when you are offered the vaccine, do not delay. It has already saved more than 10,000 lives.”
