Long Covid is closer to being considered an umbrella descriptor to what may be described as any of several different types of causes: autoimmunity, immune system dysregulation, organ injury, viral persistence, and intestinal microbiome imbalances (dysbiosis). A study recently published in JAMA, the Journal of the American Medical Association, of 9,700 patients, applies weighting to take that list of 200 common symptoms down to twelve.
From the article: "They came to a core list of 12 symptoms and assigned each symptom a score that represented the odds of it being related to COVID-19. The scores for each of the 12 symptoms ranged from 1 to 8, and the researchers added up the symptom points for each person in the trial. Based on the spectrum of score totals seen among uninfected people, the researchers concluded that a score of 12 was a reasonable cutoff for determining if someone had long COVID. And that cutoff was validated when they looked at how it correlated with the participants' reports of quality of life and health."
They are:
Symptoms Score
Loss of smell or taste 8
Post-exertional malaise (feeling tired after minor physical or mental activity) 7
Chronic cough 4
Brain fog 3
Thirst 3
Palpitations 2
Chest pain 2
Fatigue 1
Changes in sexual desire or capacity 1
Dizziness 1
Gastrointestinal symptoms 1
Abnormal movements 1
Hair loss 1
