what happens when a child gets strep
Some kids do get recurrent strep infections, thanks to a combination of bad luck and anatomy. Here's what happens: Having an infection often creates some immunity against the bacteria that caused the illness. But the tonsils of a child who has had strep sometimes seem to attract the bacteria instead. When your child has a strep infection, his tonsils and adenoids enlarge. Instead of getting smaller after the infection has been cleared up, the swelling sometimes remains, leaving the tonsils vulnerable.
