Strep throat does exhibit the same symptoms. But there are others so it cannot be said for sure that is what she has. Only a throat culture can confirm what kind of throat infection she has.
You have StrepThroat. i get it sometimes. you get fever,soar throat and in the back of mouth/throat gets whites patches
It usually doesn't show symptoms that soon. You certainly have some kind of serious throat infection with the high fevers. You should get to a doctor for a throat culture so you can get the proper treatment.
