How common is fatigue in COVID-19?

Viral illness can affect sleep, appetite, concentration, muscles, and the body’s energy demands. Fatigue may feel like heavy limbs, reduced stamina, or difficulty concentrating, even after fever or other symptoms settle. Its intensity and duration vary. Fatigue alone does not establish COVID-19, because infections, stress, medication effects, and other health problems can feel similar.

Rest when needed, drink regularly, eat simple nourishing meals, and return to activity in small steps as your energy allows. Avoid pushing through a marked crash. Follow current local advice about testing, staying home, and reducing contact when you are unwell. Record symptoms and medicines, particularly if fatigue continues after the acute illness, so a clinician can review recovery and other possible causes.

Contact a clinician if fatigue is worsening, lasts beyond expected recovery, or prevents basic activities. Get urgent help for difficulty breathing, chest pressure, new confusion, inability to stay awake, fainting, or blue or grey lips or skin.

Could another illness or medicine be adding to my fatigue? How should I pace activity? What symptoms would mean I need assessment for a complication or prolonged recovery?
