What is long COVID?

Long COVID is a condition affects some people who have been infected with COVID-19 and experience long-term symptoms

from their infection for more than one month.

CDC U.S. has estimated the proportion of people who had COVID-19 that go on to experience long covid by:

  • 13.3% at one month or longer after infection
  • 2.5% at three months or longer, based on self-reporting
  • More than 30% at 6 months among patients who were hospitalized


People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again.

People with post-COVID conditions may develop or continue to have symptoms that are hard to explain and manage.

People who experience post-COVID conditions most commonly report:

  • Tiredness or fatigue that interferes with daily life
  • Difficulty breathing or shortness of breath
  • Cough
  • Chest pain
  • Fever
  • Fast-beating or pounding heart
  • Difficulty thinking or concentrating
  • Headache
  • Dizziness when you stand up
  • Depression or anxiety
  • Diarrhea and Stomach pain
  • Joint or muscle pain

People More Likely to Develop Long COVID

Some people may be more at risk for developing post-COVID conditions (or long COVID).

Studies have shown that some groups of people may be affected more by post-COVID conditions. These are examples people who might be more at risk for developing post-COVID conditions:

  • People who have experienced more severe COVID-19 illness, especially those who were hospitalized or needed intensive care.
  • People who had underlying health conditions prior to COVID-19.
  • People who did not get a COVID-19 vaccine.
  • People who experience multisystem inflammatory syndrome (MIS) during or after COVID-19 illness.

Preventing Long COVID

  • Research suggests that people who are vaccinated but experience a breakthrough infection are less likely to report post-COVID conditions, compared to people who are unvaccinated.
  • People who are not vaccinated against COVID-19 and become infected may also be at higher risk of developing post-COVID conditions compared to people who were vaccinated and had breakthrough infections.
