Coronavirus infection rates are higher in Liverpool, St Helens and Knowsley compared with other parts of Merseyside, according to new data.
Figures estimated by the Covid Symptom Study App - developed by researchers from King's College London and health science firm ZOE - give an indication of how many people could have the virus at present in the country.
The data is based on information uploaded to the app, which has been downloaded more than four million times, rather than official government testing figures - but it has been seen as a reliable source of data throughout the crisis.
The app data suggests that the number of daily new cases of Covid-19 has stopped dropping in the UK.
The latest prevalence figures estimate that 26,020 people in the UK currently have symptomatic Covid-19, based on the daily new cases and symptoms being logged on the app.
The latest figures from the King's team suggest that the on Merseyside, St Helens has the highest estimated number of active Covid-19 cases per million people with 1,174.
That's followed by Liverpool with 1,083 and then Knowsley on 1,057.
Sefton is the fourth worst affected area for active cases according to the app, with 826 per million people.
Wirral appears to be doing considerably better than other Merseyside boroughs at present, with an estimated 538 active cases per million people.

Further afield in the Liverpool City Region there is a jump up to Halton, which is estimated to have 1,004 active cases per million people.
According to the latest COVID Symptom Study app figures, there are currently 2,103 daily new cases of COVID in the UK on average over the two weeks up to July 1, not including care homes.
This suggests that the number of daily new cases has now stopped dropping, with a definite levelling off of cases since the beginning of July.
Tim Spector, Professor of Genetic Epidemiology at King's College London, says that after months of seeing the number of COVID cases falling in the UK, those numbers are starting to “bottom out”.
He said: “We aren’t surprised to see this happening given the easing of lockdown and more and more people working and socialising.
“The team is keeping a very close eye on the data in order to allow us to spot any potential new hotspots and pick up regions with a significant increase.
“The virus is not going away any time so it is really important that people are adhering to the public health messages around social distancing, washing hands, and wearing masks.
“We were pleased to see the government taking the decision to rule that face masks should be worn in shops and other public places, as all measures are important in stopping an increase in the transmission of the virus.
“We believe the public should be aware of all the many symptoms of the virus, particularly in the early stages, and we have recently highlighted the need to look out for unusual skin rashes.
“Over time and with the help of our loyal loggers we will have a better understanding if the possible increase in cases is significant.”
