The last week in May saw 26,115 Scots attend an A&E department, the most since the final week of February 2020.
Of those, 85.7 per cent were seen and admitted, transferred or discharged within four hours – below the Scottish Government target of 95 per cent.
The figures, published by Public Health Scotland, also show 410 patients spent more than eight hours waiting to be seen at an A&E department, while a further 109 patients waited longer than 12 hours.
In the first month of the Covid-19 pandemic, when Scotland was put into lockdown, A&E patient numbers plummeted to a record low of 11,059.
Attendances gradually increased to a summer high of 24,050 in mid-August, before dropping back below 16,000 in January during the second wave of Covid-19 when restrictions were at their strictest.
But with restrictions easing and Scotland returning to some level of normality, numbers at A&E have been steadily rising recently, by around five per cent most weeks.
There were fears that the re-opening of pubs and sale of alcohol in May could produce an influx in A&E admissions, with health boards around the country urging people to take caution.
But the re-opening did not appear to cause a significant increase in emergency admissions, other than the continued steady rise in line with more of the country returning to normal.
The Royal College of Emergency Medicine has warned as A&E departments see numbers returning to pre-pandemic levels, they must assess resources and prepare now for any future waves of the virus.
