More than a million people in the UK are thought to be living with long covid - symptoms that last weeks or even months after the virus has gone.
Symptoms of long covid, the NHS says, can include extreme fatigue, sleep problems and memory or concentration issues.
There have been reports of people developing the condition, despite having had no symptoms when they tested positive for coronavirus.

Many of us take supplements on a regular basis, to feel better and boost vitamin levels.
One of these, a probiotic, has now been identified as likely to help treat long covid, according to research from a number of NHS Trusts.
A year-long investigation was undertaken by experts at Cambridge University Hospitals (CUH) NHS Foundation Trust, Bedfordshire Hospitals NHS Foundation Trust, the University of Bedfordshire, and volunteer patients across both counties.
It found treating the gut to a blend of five different friendly bacteria called lactobacillus probiotics, combined with a chicory-rich ingredient known as an inulin, could help with acute and long-term covid symptoms.
The study involved 126 people, a third of whom had an acute Covid infection with the majority reporting a wide variety of longer term symptoms lasting over 100 days.
Results, analysed by university statisticians showed that cough, fatigue, gut and well-being scores improved.
Many said gut symptoms suffered for years were also resolved.
Probiotics can be purchased in pill form from a number of health stores and pharmacies.
