My grandson got Strep constantly, it turned out that a classmate of his kept giving it to him but no one even knew she was sick until she got Scarlett Fever.
One summer I had to take him to the doctor for a school physical because his parents were busy. I just had a hunch that he had it again, something in his voice and when the Dr. pronounced him fine I asked if he would do a strep test. He told me that there was nothing to indicate that test and I asked him if he would just humor me. Thankfully he did and it was positive. The Dr. was flabbergasted.
