Conditions

Reducing frequency and severity of post-exertional malaise in people with long COVID. Infections and Infestations COVID-19 (SARS-CoV-2 infection)

Interventions

250 participants with long COVID will be randomised into intervention and control groups using a secure, independent online trial allocation service. Allocation will be stratified for age and sex.

Inclusion criteria

Inclusion criteria: 1. Adults reporting persistent symptoms which have lasted for at least 8 weeks after initial infection with COVID-19 and which interfere with day-to-day activity. 2. Participants should be recovering at home and have access to an Android (SDK16 or higher) or iPhone (iOS version 10 or higher) mobile phone.

Exclusion criteria

Exclusion criteria: 1. Currently receiving ongoing care for LC via primary or secondary care services. 2. Prior diagnosis with a comorbidity with similar symptoms (e.g. ME/CFS). 3. Currently receiving a therapy known to cause exacerbations. 4. Currently participating in another LC focussed intervention. 5.
