COVID-19 is very similar to the FLU
Influenza (flu) and COVID-19 are very similar illnesses by nature because they are both contagious respiratory illnesses. Both COVID-19 and flu share symptoms such as fever/chills, change in sense of smell/taste, cough, difficulty in breathing, sore throat, headache, vomiting, diarrhea, muscle pain, constant fatigue.
As a result, based on symptoms alone, distinguishing the Covid19 from the flu is difficult.
