We’re all used to the concept of a diary as a record – but adding in extra details of where you have been or who you may have come into contact with - could help the NHS track and trace effort.
The message comes after so-called Super Saturday which saw some pubs, bars and restaurants reopen after lockdown across the city.
“It’s vital that we come out of lockdown in the safest way possible,” says David Regan, Manchester’s Director of Public Health.
“That means taking every precaution and following the rules on social distancing, hand-washing and face coverings where needed. But, it also means that we all have an even greater part to play with NHS Test and Trace.
“If we all keep a diary - or a note on our phones - of where we have been and at what time, or who we may have come into close contact with, it can give an accurate record if needed. This would then help the NHS teams who are either testing for the disease, or, are tracing people who may have been in close range of someone who has a confirmed case.
“We all know it can be difficult to remember the exact details of events from a week ago, but just a simple memo in a diary entry can give the clarity needed to make sure that you and others are all kept safe.
"I'd also like to say a big thank you to all the effort the people of this city have already made to look after one another."
