Just three weeks ago, bosses announced coverings were no longer mandatory at the hospital with ‘immediate effect’ - but with the condition that they may reintroduce measures should there be a resurgence of the virus.
As of June 23, Barnsley’s seven-day average of cases was 61.3, while at its lowest ebb on May 18 there were just 14 new cases and the seven-day average was 21.4.
At its peak in January, the seven-day average was 1,174.9.
As of June 28, there were 24 patients in hospital with Covid - which has increased from four a month earlier.
“We recognise the contribution visiting makes to the wellbeing and the person-centred care of patients, and welcome visitors,” said a hospital spokesperson.
“We ask everyone to wear a face mask at all times during their visit, and to regularly use our hand hygiene stations.
“Please expect staff and volunteers to ask you to wear a mask if they see you without one.”
