Child has strep been on antibiotics since yesterday, taken 2 doses. should he still have a fever? its 101.5 plus a mucousy cough. when will fever stop

Treatment failure: Symptoms of an illness that will respond to a particular antibiotic usually start to improve within 3-4 days if the appropriate antibiotic was prescribed, and they were taken as directed. Relapse or persistence of symptoms is generally regarded as a treatment failure or inaccuracy of the original diagnosis (i.e. viral not bacterial). Fever from Strep usually resolves in 2-3 days with antibiotics.

Yes: After tow dose of antibiotic fever could continued ,but because of mucousy cough if it continued he should be re evaluated by his doctor
