Strep throat is caused by the bacteria called Group A beta hemolytic streptococci. All children may get strep throat although babies are felt to be at a very low risk. Typically, but certainly not always, the child gets a fever and sore throat with large tonsils that typically have pus on them. Some children will only have symptoms consisting of headache or stomach ache.
Some children develop a rash about the body which is red and has fine bumps.
The skin appears sunburned and may look like sandpaper. This rash usually appers around 24 hours after the fever. When this occurs, it is called scarlet fever. While strep throat, itself, is not dangerous, there are complications of this infection which can cause significant problems. These complications include acute rheumatic fever which may cause problems with heart and acute glomerulonephritis which can cause problems with the kidneys.
