Hi. Hope someone out there has a medical degree pertinent to this question. My 9 year old son has had strep throat 4 times in the past 4 months. It seems to always present itself a couple days after the onset of another illness, such as a common cold or stomach flu. Is it possible he is a carrier and when his immunity is compromised by another active illness, the strep bug rears it's ugly head? Similarly, could it be that one of us family members is a carrier and he is susceptible when his immunity is lowered by another illness. The doc hasn't suggested that we all get tested, but when is that protocol? As a side note, I want to assure you that he has completed each round of antibiotic as prescribed. Thanks. :?: :) :?:
