40 deaths due to Covid-19 in 24h in the UK and 2,678 new coronavirus infections. A total of 17,378 new cases in 7 days. With more enhanced testing currently taking place in south London and in Birmingham because of the variants, complacency is our greatest enemy, Dr Joe Pajak writes.


First published in April 2021.


As of today, 11,623,671 people have completed the full course of TWO vaccinations (as required with the vaccines in use in the UK currently) against Covid-19; that is equivalent to 17.40% of the total UK population (or 22.07% of the adult population, 18 years and above). While, 33,388,637 people in total have received one dose of the vaccine: that is equivalent to 49.99% of the total population (or 63.39% of the adult population, 18 years and above).

Note: We must remember that the vaccines currently used in the UK require two doses to complete the course, so there is no cause for complacency.

Vaccines continue to the best way for people to be protected from COVID-19 and have already saved thousands of lives, however there is also little doubt that the recent lockdown has contributed significantly to the downward data trends.

Back to today’s data in the UK, which indicate the sad fact that another 40 deaths have been reported in the last 24 hours due to Covid-19. While, transmission of the virus continues to be at a high level with 2,678 new cases reported in the last 24 hours.


It is also worth noting the average number of new coronavirus infections, and of deaths due to the virus, reported in the last 28 days of Covid-19 data: average (28-day) reported daily numbers of coronavirus infections (3,018) and the average (28-day) reported daily number of coronavirus deaths (31).

Latest health care data indicate that 1,879 patients suffering from Covid-19 are currently occupying hospital beds (as of 21 April), and 261 patients are requiring intensive care support (as of 22 April) – a continuing concern for our NHS.

Additional surge testing and genomic sequencing has been deployed in Lambeth, in Wandsworth, and in Birmingham where confirmed cases of a variant of concern have been identified.


Note: The data for deaths attributed to COVID-19 – each following a reported positive test result for COVID-19 within 28 days of their death.

State of the UK epidemic:
To better understand the state of the epidemic in the UK, the UK government recommend “focusing on indicators for the 4 nations of the UK individually, rather than an average value across the UK.” Estimates of the R value and growth rate for different nations can be found via this link.

New infections and deaths in the last 28 days:

  • 84,504 new cases in total 🦠
  • 873 deaths in total

Days since:

  • 449 days since the first reported UK case
  • 413 days since the first reported UK death

The total number of people whose death certificate mentioned Covid-19 as one of the causes: 150,841 – Registered up to Friday 9 April 2021.


These data, and trends, are shared to focus some light on the situation. We must never forget the data represent real people suffering, real people dying

21 April – Removal of 2 historical deaths in Scotland:
Two previously reported, confirmed COVID-19 deaths have been removed. This was due to further investigation by Public Health Scotland into the length of time between the deaths and the positive COVID-19 test results. Because of this, the cumulative total number of confirmed COVID-19 deaths reported for Scotland is 7,643 instead of 7,645. The UK cumulative total has also been adjusted.
