If feeling lethargic and bodys aches and sore throat on and off and blocked nose - could this be covid?

Can call Dr on video: Throat pain can be from a strep throat infection (antibiotics needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, a person sees the doctor (call first) if the sore throat is bothersome, recurrent, or doesn't go away quickly. COVID-19 infections tend to have cough, whereas strep usually lacks cough but has more throat pain.
