What Is Strep Throat? Strep throat is a disease caused by a tiny ball-shaped type of bacteria (say: bak-TEER-ee-uh) called group A streptococcus (say: strep-tuh-KAH-kus). If a kid has strep throat, the doctor will give him or her medicine called an antibiotic (say: an-tye-bye-AH-tik) to kill the strep bacteria. That's good news because sometimes strep throat can get worse and cause problems with other parts of a kid's body. For example, untreated strep can cause arthritis (say: ar-THRY-tis), kidney problems, or heart problems from a disease called rheumatic (say: roo-MA-tick) fever. Most of the time kids get the medicine they need and recover from strep throat very quickly. After taking the medicine for 24 hours, you will feel a lot better and will no longer be contagious.
