Millions of people who have had COVID-19 find themselves suffering from a host of debilitating symptoms that can persist for weeks or even months after their initial coronavirus infection fades.
This phenomenon, known as long COVID, has puzzled experts since near the start of the pandemic. And while research is starting to shore up some answers, Greg Vanichkachorn, M.D., formerly with Mayo Clinic, says, “we don’t really have [long COVID] nailed down yet.”
A new definition for long COVID
On June 11, 2024, National Academies of Sciences, Engineering, and Medicine suggested a new, universal definition for long COVID. The group defines long COVID as “an infection-associated chronic condition that occurs after COVID-19 infection and is present for at least three months as a continuous, relapsing and remitting, or progressive disease state that affects one or more organ systems.”
A big reason is because “it looks like more and more symptoms can be associated with this condition,” says Vanichkachorn, an occupational and aerospace medicine specialist who was the medical director of Mayo Clinic’s COVID Activity Rehabilitation Program and is now a physician with Delta Air Lines.
In fact, the list of the most commonly reported long COVID symptoms maintained by the Centers for Disease Control and Prevention (CDC) includes nearly 20, ranging from neurological complications to digestive disorders. Some studies have uncovered more than 50 long-term effects of COVID-19, adding issues such as hair loss and vision loss to the mix. Others estimate that number is much higher — closer to 200.
Still, some symptoms seem to be more prevalent.
A study published May 25, 2023, in the journal JAMA identified 12 symptoms that most set apart people with and without long COVID. They are:
- Post-exertional malaise, or the worsening of symptoms following physical or mental exertion — even minor effort.
- Fatigue.
- Brain fog.
- Dizziness.
- Gastrointestinal symptoms.
- Heart palpitations.
- Issues with sexual desire or capacity.
- Loss of smell or taste.
- Thirst.
- Chronic cough.
- Chest pain.
- Abnormal movements.
New research from AARP reflects similar findings, with older adults reporting that their most common long COVID symptoms are fatigue, brain fog, cough, and loss of taste or smell. Results from the survey, published Feb. 6, 2024, show that nearly 1 in 5 adults ages 50 and older have experienced long COVID.
