Long COVID-19's myriad risk factors and symptoms have been a key focus for study as experts aim to learn more about the effects and duration in humans. Now, emerging research may have narrowed the swath of symptoms to seven prominent conditions.
"We identify that some diagnoses commonly described as 'long COVID' do not appear significantly more frequent post-COVID-19 infection compared with other common [viral respiratory infections]," researchers wrote.
The team of researchers from the University of Missouri in Columbia looked at 17,487 patients who were diagnosed with COVID-19 before April 14 and found that coronavirus was directly associated with diagnoses of the following seven long COVID symptoms:
- Palpitations
- Hair loss
- Fatigue
- Chest pain
- Dyspnea
- Joint pain
- Obesity
