COVID-19 is a novel (new) coronavirus, not previously identified in humans, responsible for an outbreak of respiratory illness that became a global pandemic in 2020. COVID-19 is different from other coronaviruses that cause mild illness, such as the common cold.
Lingering symptoms after COVID-19 are called long COVID, long-haul COVID, post-acute COVID-19, long-term effects of COVID, chronic COVID, or Post-Acute Coronavirus Disease Syndrome (PACS), and people may experience these lingering symptoms for at least four weeks or even a few months after first being infected with the virus that causes COVID-19. In some cases, symptoms will go away and come back.
There are three types of long COVID:
- Those who do not recover completely and have ongoing symptoms
- Those who have symptoms that appear after recovery
- Those whose symptoms are related to chronic hospitalization
Lingering symptoms after COVID-19 are similar to many symptoms of COVID-19 and may include:
- Cough
- Shortness of breath
- Difficulty breathing
- Tiredness/fatigue
- Symptoms that worsen after physical or mental activities
- Difficulty thinking or concentrating (“brain fog”)
- Stomach pain
- Loss of appetite
- Headache
- Chest pain
- Heart palpitations
- Joint or muscle pain
- Change in smell or taste
- Numbness and tingling or “pins and needles” feeling
- Diarrhea
- Sleep problems/insomnia
- Fever
- Dizziness on standing
- Rash
- Mood changes
- Changes in menstrual period cycles
- Anxiety
- Depression
In people who had severe illness with COVID-19, lingering symptoms may include:
- Multiorgan effects
- Autoimmune conditions
- The immune system mistakenly attacks healthy cells in the body causing inflammation or tissue damage
- Multisystem inflammatory syndrome (MIS) (rare)
- Affects children more often than adults
- Different body parts can become inflamed
Lingering symptoms after COVID-19 that can occur in patients who are hospitalized or who had severe illness may include:
- Severe weakness and exhaustion during the recovery period
- Post-intensive care syndrome (PICS)
- Health effects that start when a person is in an intensive care unit (ICU) and continue after a person goes home
- Severe weakness, problems with thinking and judgment, and post-traumatic stress disorder (PTSD)
What Causes Lingering COVID Symptoms?
Lingering symptoms after COVID-19 (long COVID) are caused by previous infection with the coronavirus that causes COVID-19.
Factors that may contribute to development of long COVID may include:
- Cell damage from the virus
- Chronic hospitalization due to the illness
How Are Long Hauler Symptoms After COVID-19 Diagnosed?
There are no specific criteria to diagnose lingering symptoms after COVID-19 (long COVID) but in general, the condition is diagnosed based on signs and symptoms that:
- Develop during or following an infection consistent with COVID-19
- Continue for more than 12 weeks and are not explained by an alternative diagnosis
How Are Long-Term Effects of COVID Treated?
There is no specific treatment for lingering symptoms after COVID-19 (long COVID). The goal of home treatment is to relieve symptoms.
Home treatment for lingering fatigue and breathlessness due to long COVID may include:
- Pacing yourself
- Breaking down tasks into smaller chunks
- Taking frequent short rests, resting before you become exhausted.
- Gradually increasing exercise if possible
Home treatment for lingering mood problems such as depression or anxiety due to long COVID may include:
- Being compassionate to yourself during recovery
- Connecting with others and keeping in touch with loved ones
- Keeping up a daily routine to maintain stability
- Staying active to help release endorphins and improve mood
Home treatment for lingering thinking or memory problems due to long COVID may include:
- Taking notes to help remember things
- Reducing distractions when possible
- Planning before attempting things and breaking things down into steps
Home treatment for lingering joint or muscle pain due to long COVID may include:
