A recent CDC study says that 1 in 5 of U.S. adults stricken with COVID-19 have developed conditions that could be considered long COVID, which the agency defines as symptoms lasting at least four weeks after infection.

The CDC says the following symptoms are the most common for this complex and poorly understood condition:

  • Tiredness or fatigue that interferes with daily life
  • Difficulty breathing, shortness of breath, chest pain
  • Difficulty thinking or concentrating (sometimes referred to as “brain fog”)
  • Headache
  • Sleep problems
  • Anxiety
  • Digestive issues
  • Joint or muscle pain
