Breathlessness
Breathlessness is not such a subtle sign of COVID-19, that is if it is accompanied by a fever and a sore throat. However, if breathlessness is all you had for a short time, it is possible that you had the virus. You may have thought it was also allergies since it seemed atypical and you did not feel it was necessary to visit the hospital. You just got off lucky if you had the virus.
