It appears from you description that your daughter had a sore throat with Streptococcus. I believe this germ was identified on throat culture and also the microbiology lab was able to identify the type of Streptococcus. It is not unusual to behave like your daughter is behaving after any severe illness. She would recover with time. Make sure that you check her throat status on follow up i.e. the throat swab culture has become negative, as streptococcoal infections sometimes may have systemic manifestations which may appear after the throat infection has cleared. Give her healthy nutritious diet with lot of liquids, it will help her recover faster.
