Coronavirus -- symptoms of Covid

Sure Signs You've Already Had COVID, According to New Study

1. Amnosia - loss of smell
2. Ageusia - loss of taste
3. Difficulty concentrating
4. Dyspnea - shortness of breath
5. Memory loss
6. Confusion
7. Headache
8. Heart palpitations
9. Chest pain
10. Pain with deep breaths
11. Dizziness
12. Tachycardia fast heart rate
13. Fatigue

I assume the more symptoms you have, the stronger the sign. Some singly, e.g. headache, chest pain, dizziness, fatigue seems more likely a sign of something else.

Happy New Year and take care.
