The third and final symptom shown in the above picture from the US Center for Disease Control (CDC) is shortness of breath. Take a deep breath and breathe in. Then, breathe out. If you can take a deep breath, then you are not suffering this symptom from the coronavirus. If you are wheezing and if you are not a smoker, then you could potentially have Covid-19.
The combination of the three symptoms (fever, cough, shortness of breath) is a clear indication that a person has the coronavirus. This combination of symptoms are completely different from a common cold, which includes fever and a cough. However a cold does not bring about shortness of breath because a common cold attacks the upper respiratory system, while the coronavirus attacks the lower part of the lungs in your midsection.
As a result, other symptoms of a common cold are a runny nose, chest congestion, and headaches. These symptoms are not symptoms of the coronavirus.
