Why It Matters

Evidence shows that unvaccinated individuals are far more vulnerable to becoming seriously ill and dying from COVID-19 than those who have been vaccinated.

Long COVID” can happen to anyone who has had COVID-19, even if the illness was mild or they had no symptoms.

People with Long COVID report experiencing different combinations of the following symptoms or conditions, which can last for weeks or months following infection:

  • Tiredness or fatigue
  • Difficulty thinking or concentrating (sometimes referred to as “brain fog”)
  • Headache
  • Loss of smell or taste
  • Dizziness on standing
  • Fast-beating or pounding heart
  • Chest pain
  • Difficulty breathing or shortness of breath
  • Cough
  • Joint or muscle pain
  • Depression or anxiety
  • Fever
  • Symptoms that get worse after physical or mental activities

The Centers for Disease Control and Prevention continues to work to identify how common these long-term effects are, who is most likely to get them and whether symptoms eventually resolve. Studies are underway to investigate post-COVID conditions. These studies will help us better understand both post-COVID conditions and how to treat patients with these long-term effects.
