Strep throat is an infection in the throat and tonsils caused by a type of bacteria called group A Streptococcus (group A strep) . This makes strep throat different from most other cases of sore throat, which occur due to viruses. Group A strep bacteria are very contagious and can be spread through respiratory droplets or direct contact with an infected person. People infected with group A strep may not have symptoms or seem sick, but they can still spread the bacteria to others.

Symptoms of strep throat can include throat pain, painful swallowing, a sore throat that lasts longer than 48 hours, fever, swollen lymph glands, and a sore throat accompanied by a rash. If left untreated, strep throat can cause complications such as kidney inflammation or rheumatic fever.

Strep throat is most common in children, but it can affect people of all ages. If you or your child has signs or symptoms of strep throat, it is important to see a doctor for prompt testing and treatment. Treatment typically involves antibiotics to clear the infection.
