Following the pandemic of COVID-19, in December 2021, 862,000 people living in private households in the UK were experiencing self-reported post COVID symptoms (also known as long COVID) where COVID-19 was confirmed or suspected at least 12 weeks prior. If you have experienced fatigue (the most commonly reported symptom), followed by shortness of breath, muscle ache and difficulty concentrating 12 weeks after symptoms first presented you may have Post COVID Syndrome.
