A Lidl supermarket was forced to close after staff members tested positive for coronavirus.
The Middlesbrough store shut its doors yesterday and could not reopen today due to a shortage of staff.
Shoppers who contacted Teesside Live said that they'd been told the supermarket would reopen on Monday.
A Lidl spokeswoman said: "All supermarkets are currently operating under exceptional circumstances, and the safety of our colleagues and customers is critical to us.
"We have been in touch with those members of our team that have tested positive for Covid-19, to offer our support and wish them a speedy recovery.
"We fully understand that this is a concerning and difficult time, not only for our own workforce but for the whole country.
"We have been closely following government advice throughout this period and have stringent measures in place across all of our business areas to protect colleagues and customers."
Lidl said it would reopen the supermarket as soon as it could.
"Our teams are all playing a crucial role in continuing to feed communities across the country," the spokeswoman continued.
"It is therefore vitally important that we reopen the store as soon as we can, to ensure that households have access to the essential food and products they need."
On Thursday, Middlesbrough Council confirmed that the TS3 postcode - home to the Lidl store - had a high mortality rate for coronavirus deaths.
NHS data showed there may be an increased risk of infection and illness in the postcode area.
While it will be some time before all the factors are understood, present figures show a high rate of deaths for patients at James Cook University Hospital from the area.
The postcode covers several areas including Berwick Hills, North Ormesby, Pallister Park, Brambles Farm, Thorntree and Park End.
Those living in the area have been receiving a leaflet reminder of the importance of following the coronavirus lockdown guidelines.
