<s>[INST] My daughter is 2 years old, almost 3 and she was told by her doctor that she has group b strep. How did she get this? I do not have step b. I was tested when I was pregnant with her and it was negative. Also, she was delivered c-section. Will she have any complications through life? And will she always have step b? [/INST] group b streptococci are usually not harmful at this age group. they live normally on body surface and certain body cavities. these sometime cause disease such as pneumonia, meningitis which needs treatment. so u need not to worry. </s>
