COVID cough is characterised by an increase in the intensity of the existing cough or the onset of a new one.
COVID cough is mostly persistent.
A distinct sign of COVID cough is that it is dry in nature. Though several health agencies just say that cough is a symptom of COVID, many of those who have been infected say it is a dry cough mostly without any phlegm.
Dry cough is painful when it lingers in the body for a longer duration. It affects the throat, the voice and also leads to shortness of breath in the individual.
Many people experience frequent episodes of long dry cough.
Frequent coughing or painful loops of periodic coughing leads to fatigue as well.
