Blackpool Coronavirus Weekly Summary

Last Modified 21/04/2021 12:16:19 Share this page


The trend in deaths of Blackpool residents is shown in the chart below.  The yellow bars show the deaths identified as Covid-19 on death certificates.  The number of deaths quickly came to a peak in mid-April 2020 with a slower fall over summer before increasing again from mid-October. Deaths from Covid-19 are once again decreasing. The black line allows a comparison of the total number of deaths currently being recorded each week with the average number we have seen in the last five years.  This gap between the current number of deaths and what we would expect based on the pattern from previous years is often described as the number of ‘excess deaths’.

    • In the period up to 17 April, 470 residents of Blackpool have COVID-19 recorded on their death certificate.

Comparing the numbers of deaths in different areas is more meaningful if we take account of their population sizes and their age and sex distributions.  This is particularly important for COVID-19, as we know that it disproportionately impacts older people and to some extent males.  The chart below takes these factors into account. All regions recorded increases in mortality rates involving COVID-19 between March and April, followed by decreases in summer 2020. Further spikes occurred over the winter and now mortality from COVID-19 is decreasing across all areas. While Blackpool’s death rate is higher than the England rate, it is similar to the average death rate across the North West as a whole.

Testing for COVID-19 allows the diagnosis of an individual, but also allows us to track the progress of the epidemic.  Testing has been undertaken in two ‘pillars’:

    • Pillar 1: swab testing in Public Health England (PHE) labs and NHS hospitals for those with a clinical need, and health and care workers
    • Pillar 2: swab testing for the wider population, as set out in government guidance

Pillar 1 testing has been undertaken since very early in the epidemic, whereas pillar 2 testing was introduced gradually from mid-April.  The chart below tracks pillar 1 and pillar 2 confirmed cases, for Blackpool residents over time.

    • To date (18 April 2021) there have been 9,193 confirmed cases in Blackpool since the outbreak began.
    • This is roughly equal to 66 people out of every 1,000 that live in the town.
    • In the 7 days to the 15 April, 21 residents tested positive for COVID-19, which represents a weekly rate of 15.1 per 100,000 residents.
    • In the week ending 15 April, 0.3% of tests taken by residents in Blackpool were positive.

Coronavirus (COVID-19) Infection Survey pilot

COVID-19 can present as a mild illness in many people and can be totally asymptomatic in others.  This means that many people who have COVID-19 will not be tested for the virus, and therefore testing cannot give us a complete picture of what is happening.  The Office for National Statistics (ONS) and the University of Oxford are conducting the Coronavirus Infection Survey Pilot to assess the incidence (the number of new cases per week) and the prevalence (the number of people who have the virus at any one time) of COVID-19, as well as to gain further insight into what factors influence catching the virus.

    • Prevalence: An estimated 112,600 people (95% credible interval: 96,700 to 130,100) within the community population in England had COVID-19 in the week ending 10 April 2021, equating to around 1 in 480 individuals.

Modelling suggests that in England, the percentage of people testing positive for the coronavirus (COVID-19) decreased in the week ending 10 April 2021.

The highest percentage of people testing positive was observed in the North West. The percentage of people testing positive decreased in Yorkshire and The Humber and the South East. The trend over the most recent week is uncertain in the remaining regions.

The percentages of people testing positive for the coronavirus (COVID-19) in England have decreased in most age groups, except school Years 7 to 11 and in those aged 50 to 69 years where the trend is uncertain.

Caution should be taken in over-interpreting small movements in the latest trends.

The chart below present estimates of infection rates over time. The estimate shows the number of infections has decreased in recent weeks.

1.These statistics refer to infections reported in the community, by which is meant private households. These figures exclude infections reported in hospitals, care homes or other institutional settings.
2.It is important to note that the results for the most recent period are provisional, as the CIS is still receiving swab test results. This may result in further revisions to the figure.

R Value

The reproduction number (R) is the average number of secondary infections produced by 1 infected person.

An R number of 1 means that on average every person who is infected will infect 1 other person, meaning the total number of new infections is stable. If R is 2, on average, each infected person infects 2 more people. If R is 0.5 then on average for each 2 infected people, there will be only 1 new infection. If R is greater than 1 the epidemic is generally seen to be growing, if R is less than 1 the epidemic is shrinking.

R is not the only important measure of the epidemic. R indicates whether the epidemic is getting bigger or smaller but not how large it is. The number of people currently infected with coronavirus (COVID-19) – and so able to pass it on – is very important. 

The R value cannot be measured or calculated directly but must be inferred from the trend observed in epidemiological data such as hospital admissions, ICU admissions and deaths. 

The estimated R values for areas with smaller populations are much less certain, as there is less information available to produce a model.  A number of models have been created to estimate an R value for the North West of England.  These models currently suggest the R value for the North West is similar to the value for the United Kingdom as a whole.

Range for the UK                  0.7 - 1.0





Range for the North West  0.6 - 0.9

Growth Rate

The growth rate reflects how quickly the number of infections are changing day by day and it is an approximation of the change in number infections each day. If the growth rate is greater than zero (+ positive), then the disease will grow. If the growth rate is less than zero (- negative) then the disease will shrink.

The size of the growth rate indicates the speed of change. A growth rate of +5% will grow faster than one with a growth rate of +1%. Likewise, a disease with a growth rate of -4% will be shrinking faster than a disease with growth rate of -1%.

Latest growth rates (percentage per day)

Range for the UK                        -6% to -1%            



Range for the North West        -7% to -2%

Vaccination coverage

The NHS started administering vaccinations for COVID-19 in England on 8 December 2020

JCVI priority groups 1 to 9 are:

  1. Residents in a care home for older adults and their carers
  2. All those 80 years of age and over and frontline health and social care workers
  3. All those 75 years of age and over
  4. All those 70 years of age and over and clinically extremely vulnerable individuals
  5. All those 65 years of age and over
  6. All individuals aged 16 to 64 years with underlying health conditions which put them at higher risk of serious disease and mortality, unpaid carers and residents in a care home for younger adults
  7. All those 60 years of age and over
  8. All those 55 years of age and over
  9. All those 50 years of age and over
