Dear Sir/Madam I am sorry to hear that your step daughter is ill with sore throat
. Strepto coccus infection should be treated with antibiotics as soon as the diagnosis is done and your doctor has done excellent job. The medications she is taking are all ok.It takes few days for the antibiotics to work. Mouth care is very imoptant while she is ill and I would advise to encourage her to use mouth wash two to three times daily.Make sure she takes adequate fluids. Streptococcus
infections in the past caused complications affeting the heart and used to called rheumatic fever
but that problem almost gone. I do not feel any other problem is there, but I strongly advise to contact your Doctor if you are worried. I wish her complete and speedy recovery. Kindest regards.
