At the time of writing this briefing, Scotland has the highest rate of Covid-19 infections in Europe,  yet no additional restrictions nor mitigation measures are being considered by the Scottish Government. The Government is justifying this inaction by the fact that far less people are being treated in hospital than during the first two waves of Covid, thanks to the fact that the majority of people over 50 as well as particularly vulnerable younger people are now fully vaccinated.
The age groups with the highest rates of infections since lockdown was lifted have been those between 15 and 24, followed by adults age 25-44 and children under 15. 
Focusing on hospitalisation and deaths only rather than all infections means ignoring the long-term health effects and disability suffered by a significant minority of people of all ages after Covid-19 infections, regardless of how mild or severe the initial symptoms had been.
In England, specialist help for Long Covid is now being provided at 60 sites,  although some sufferers report treatment delays of several months.  15 new hubs for children with Long Covid are being set up.  However, the Scottish Government stated earlier in June 2021 that no specialist Long Covid clinics are being funded or planned in Scotland. People with Long Covid in Scotland are being referred to a range of different services, whereas what they need in relation to their complex needs is a specialist service within which a range of NHS professionals, particularly those in the allied services sector, are coordinated. This means that people with Long Covid are getting even less overall access to help and support in Scotland than in England, as well as less appropriate services.
Finally, people suffering from Long Covid across the UK are routinely experiencing discrimination and disadvantage at work and the Trade Union Congress is calling for Long Covid to be classed as a disability under the Equality Act.  While equality legislation is not devolved in Scotland, far more can and must be done to support people affected by this condition.
The term refers to new symptoms of ill health that people suffer for more than four weeks – but often far longer – after a Covid infection. According to a survey of 2,550 adults with Long Covid, the main persisting symptoms were exhaustion, chest tightness, shortness of breath and headache, with cognitive problems (brain fog, concentration and memory problems) and palpitations becoming more common over time. However there are other symptoms too. 83% reported symptoms which affected at least three organ systems. According to the authors: “Findings from this survey indicate that Long Covid is a debilitating multisystem illness for many of those experiencing it. For most participants, several of their initial symptoms became less prevalent with time, with the stark exception of cognitive dysfunction and palpitations. However, for a minority of participants who had extensive multisystem involvement from the start, many symptoms tended to become more common with time.”
The underlying biology of Long Covid is not yet understood. And, as an article in the science magazine Nature states: “preliminary data suggest that long COVID could be several disorders lumped into one”. 
One recent finding from a preprint (publicly posted prior to peer review) longitudinal study in the UK  is that people who have had Covid-19 infections, compared to ones never infected, have a statistically significant “loss of grey matter” in certain areas of the brain. How far brain damage caused by Covid-19 is responsible for some Long Covid symptoms remains unknown. As long ago as October 2020, a Harvard Medical School neurologist commented: “Particularly troubling is increasing evidence that there may be mild — but very real — brain damage that occurs in many survivors, causing pervasive yet subtle cognitive, behavioural, and psychological problems. 
According to figures by the Office off National Statistics (ONS), in early March 2021, 1.1 million people reported having suffered symptoms for more than four weeks, 697,000 of them for more than 12 weeks, and 70,000 for more than one year. The large majority of them reported that symptoms were severe enough to limit their day-to-day activities.
From an ONS study, 13.7% of people who had tested positive for Covid suffered at least 12 weeks of symptoms. The most affected age group was people age 35-49, i.e. people most of whom are not fully vaccinated at the time of writing this briefing. However, Long Covid affects people of any age, including children. Not surprisingly, frontline workers have been particularly affected. 
It is therefore inevitable that thousands of people who are being infected by Covid-19 in Scotland will go on to suffer health problems for many months. The long-term outlook for those who do not recover within a year remains unknown.
