COVID19 Deaths #2 – Are Public Health England’s Figures Misleading?

July 25, 2020 By Nigel Marriott

During the first wave of the COVID19 epidemic, the daily number of deaths published by Public Health England (PHE) has been the main headline in the news.  On 17th July, Matt Hancock, Secretary of State for Health, called for a review of this time series after a blog published by Yoon Loke & Carl Heneghan of Oxford University questioned whether definition used by this time series was appropriate.  I myself had noticed a change in the PHEr time series in my tracker of COVID19 deaths in England but I hadn’t understood why this might have been the case.  After looking at the data again in more detail, I have concluded that this time series is overestimating the number of deaths by 42 +/- 13 per day since the 23rd May and it needs to be revised otherwise it will create confusion should a second wave come.

Last updated on 25th July 2020 – future updates will be infrequent.

The latest data for deaths due to COVID19 (Coronavirus) in England as of Friday 24th July 2020 show that the first wave of the pandemic is now over when one looks as excess deaths.  People will still be dying of COVID19 for weeks yet but the overall number of excess deaths is now negative.

COVID19 Deaths #2H – Estimated Excess Deaths in England up to 26th June

June 28, 2020 By Nigel Marriott

In many countries across the world, the total effect of the Coronavirus pandemic is now being measured using the concept of Excess Deaths.  However, publication of such data by the Office of National Statistics for England is up to 2 weeks slower than the daily deaths published by Public Health England.  In this post, I update my model which uses the PHE series to estimate what the ONS will publish for excess deaths in England on Tuesday 30th June.
