To understand the levels and the spread of Coronavirus (COVID-19) in Manchester, we use several different pieces of information. These include:
- The number of people with a newly confirmed diagnosis of COVID-19 based on a laboratory test (‘incidence’). This is sometimes also presented as a rate per 100,000 population.
- The number of tests for COVID-19 that are conducted (also sometimes presented as a rate per 100,000 population)
- The proportion of tests that have a positive result (‘positivity’)
- The number of deaths where COVID-19 was mentioned somewhere on the death certificate (‘mortality’)
To give a full picture of what the data tells us, we use a full week’s data. Sometimes it takes a few days for test results to be processed, and this can affect figures for the most recent days, so we don’t include data for the most recent four days in our analysis.
Saturday 10 July to Friday 16 July 2021
The most up-to-date and complete information we have is for Saturday 10 July to Friday 16 July 2021. In this period there were:
- 3,210 people with a newly confirmed diagnosis of COVID-19 living in Manchester (a rate of 580.6 per 100,000 population). In the previous 7-day period there were 2,752 people with a newly confirmed diagnosis of COVID-19 living in Manchester (a rate of 497.8 per 100,000)
- 25,411 laboratory confirmed PCR tests for COVID-19 carried out on Manchester residents - a rate of 4,596.3 tests per 100,000 population. In the previous week, 26,347 tests were conducted - a rate of 4,765.6 per 100,000 population.
- 25,824 tests for COVID-19 carried out on people without symptoms (‘asymptomatic tests’) - a rate of 4,671.0 per 100,000 population. In the previous week, 27,347 tests of this type were carried out (a rate of 4,946.5 per 100,000 population).
- Of the 25,411 PCR tests conducted, 13.0% resulted in a positive diagnosis. This compares with 10.9% of tests conducted in the previous weeks.
In the week ending 9 July 2021, there were 6 registered deaths among Manchester resident that involved COVID-19. Since the beginning of the pandemic, there have been 1,065 deaths involving COVID-19 among people living in Manchester

About this data
On 16 November, Public Health England (PHE) updated the way it records the location of people who test positive or negative for COVID-19. Cases are now allocated to a local authority based on the address given at the point of testing rather than using the address recorded on a patient’s NHS Summary Care Record. This better reflects the true distribution of cases and testing. However, this change may give rise to differences in the number and rate of cases in Manchester previously reported on this website.
Data on the number of confirmed cases of COVID-19 now includes lateral flow device (LFD) tests that test for the presence of SARS-CoV-2 virus in people without symptoms. These are swab tests that give results in less than an hour, without needing to go to a laboratory. However, only PCR (i.e. laboratory confirmed) tests are included in testing rates and positivity. This is because the introduction of large numbers of LFD tests severely skews testing and positivity rates and prevents consistent comparison over time.
As a result of the decreasing prevalence of COVID-19, the government has re-introduced the requirement for people to take a confirmatory PCR test following a positive LFD test. As a result of this change, people who have tested positive following an initial LFD test but have subsequently tested negative following a later PCR test are now counted as ‘false positives’ and are no longer reported as confirmed cases. These cases are then removed from the published figures. People who have had a positive LFD test but have not taken a follow-up PCR test are still counted as cases to minimise the risk of under-reporting.
In order to be consistent, we are using figures from the same sources as those used by the Greater Manchester Combined Authority (GMCA) in their GM COVID-19 Situation Report Dashboard.
Central government also releases a range of key statistics relating to COVID-19 in Manchester, including data on testing, newly identified cases, healthcare and deaths. This information is published on the Coronavirus (COVID-19) in the UK website. This website also includes an interactive map showing the number of cases of COVID-19 by Middle Super Output Area (MSOA). MSOAs are small geographical areas with a population of around 7,200 people living in them. There are 57 of these MSOAs in Manchester. The data in the map is updated each weekday and shows the latest 7 days for which a complete set of data are available.
