My pregnant daughter just found out that she has streptococcus B. It sounds like it can be very serious to her and the baby. She is being treated with antibiotics and will be treated during her labor. She was diagnosed with CFS about a year ago and I was wondering if the streptococcus B could have attributed to that? I am so ignorant when it comes to viruses and bacteria. The streptococcus B is a bacteria? She is evidently a carrier. I had never heard of it until yesterday. Could anyone enlighten me on this.
