Long COVID FAQs: common questions answered

When you or someone you love is first diagnosed with long COVID, it is normal to have a lot of questions. Because the condition is new, fast-moving, and often politicised, clear answers can be hard to find.

Yes. Long COVID is a recognised long-term condition, covered in UK clinical guidance under NICE NG188. The NHS, the World Health Organization, and major international research bodies have all formally recognised it.

Research has identified measurable physical changes in many people with long COVID. These include persistent viral material in tissue, altered immune markers, autonomic dysfunction, and vascular changes.

The condition is heterogeneous and not all the mechanisms are understood. But the idea that long COVID is ‘in your head’ reflects a political or personal position rather than the current evidence.

There is no cure for long COVID yet. Individual symptoms can often be eased through targeted treatment, pacing, and adjustments to daily life.

Some people recover fully, many improve to some degree, and others remain unwell long-term. Trajectories vary widely and cannot be predicted at diagnosis.

They overlap a great deal, and a significant proportion of people with long COVID also meet the ME/CFS criteria.

The main difference is that ME/CFS is defined by post-exertional malaise, while long COVID may or may not involve it. Long COVID also affects a wider range of body systems.

Where long COVID symptoms map onto ME/CFS, ME/CFS management approaches generally apply, particularly pacing.

Our what is long COVID guide sets out the distinctions in full.

Most people who have COVID-19 recover within a few weeks. Long COVID is distinguished by symptoms that persist well beyond the usual recovery period, typically beyond twelve weeks under NICE NG188. They must also not be better explained by another condition.

Three months is a useful marker. If your symptoms are still affecting daily life that long after a COVID-19 infection, it is reasonable to ask your GP about an assessment.

Long COVID is sometimes mistaken for depression or burnout because all three can involve profound fatigue and reduced function. They are not the same.

Depression involves persistent low mood and loss of interest in things the person used to enjoy. People with long COVID typically retain that interest, but their bodies do not cooperate with it.

Depression is more common among people with long COVID than in the general population. That reflects the weight of living with persistent symptoms and an uncertain recovery, not a psychological cause of the condition.

Research published by major health bodies suggests that vaccination before infection reduces, but does not eliminate, the likelihood of developing long COVID. People who are vaccinated can still develop long COVID, and reinfection carries renewed risk even for those who recovered from earlier infections.

This is an area where research continues and where findings are sometimes contested in public debate. The organisations listed on our resources page are the most reliable sources for current evidence.

Not reliably. Mild and even asymptomatic infections can be followed by significant long COVID, and some people hospitalised with severe acute illness recover fully.

Our what is long COVID guide covers this alongside the other risk patterns research has identified.

Yes. Long COVID affects children and young people, though it is less commonly recognised than in adults. Symptoms in children can include fatigue, cognitive difficulties, headaches, and digestive problems.

Long COVID in children is particularly underserved in mainstream coverage and research. Long Covid Kids is the main UK-based charity focused on this area and a reliable starting point for families.

This depends on whether your long COVID includes post-exertional malaise (PEM).

For people with PEM, structured exercise programmes, including graded exercise approaches, have been associated with documented harm. If activity reliably causes symptoms to worsen 12 to 48 hours later, structured exercise is not safe, and pacing is the appropriate approach instead.

Without PEM, gentle activity kept within your tolerance may help. Starting low, going slow, and stopping if things get worse is more reliable than any prescribed programme.

If you are unsure, it is safer to assume you might have PEM and pace until you know more.

In the UK, long COVID diagnosis usually starts with your GP. They will take a history and rule out other conditions with similar symptoms. Where appropriate, they can refer you to a specialised NHS long COVID clinic, though provision has narrowed a great deal since 2024.

There is no single test for long COVID. Diagnosis is clinical, based on the pattern and persistence of symptoms following a COVID-19 infection. Keeping a symptom diary before your appointment helps significantly.

There is no single answer. Most effective approaches combine several strategies rather than relying on one. Those are pacing to stay within your energy envelope, targeted treatment of specific symptoms, adjustments to work and daily life, and emotional support.
