My daughter has had a high temperature (around 37 degrees), sore throat and headaches for 2 days. she is responding to medication. should i have her tested for covid19?

Maybe. Do video w/Dr: 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.
