Good day i have some flu symptoms like sore throat, headache, body ache and need some advice?

Not an advice forum: 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.
